My invention relates to rifles and particularly to rifles having a sliding bolt for moving the cartridge into the receiving chamber.

An object of the invention resides in providing a lever action for operating the bolt.

A still further object of the invention resides in providing a compound lever action in which the leverage on the bolt is greatest during unlocking and locking and in which greater movement and less force is procured after the bolt has been unlocked to move the cartridge into and out of the cartridge chamber.

An object of the invention resides in constructing the lever action with two levers, one

of said levers having a greater leverage than the other and operating upon the bolt during the locking and unlocking thereof.

A feature of the invention resides in pivoting one of said levers to the frame of the rifle and in 9 pivoting the other lever to said first named lever. An object of the invention resides in providing said levers with engaging heads for engaging the bolt housing, the head of one lever becoming disengaged from the bolt housing upon engagement of the other lever head therewith.

A feature of the invention resides in providing guides for guiding the movement of said levers to cause the same to engage and disengage th bolt housing at the proper times. 1 D Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

Through years of constant usage the bolt type gun has found desired favor, particularly with high powered cartridges due to the sturdy construction of the same and due to the ability of such type of gun to resist the shock occasioned through discharge of the gun. The bolt type of gun, however, has one disadvantage and that is that it is slow and awkward to manipulate. The present invention seeks to overcome this difilculty by providing a lever action which may be used in conjunction with the bolt for operating the bolt, said lever action functioning in the customary manner and moving the bolt both during locking movement and movement away from the receiver.

For the purpose of illustrating my invention, I have shown in Fig. l a rifle which is indicated in its entirety by the reference character A. This rifle comprises a stock H) which carries a barrel II. The barrel II has attached to it at the receiver end a. frame I! in which is slidably mounted a bolt mechanism 30 which includes a bolt l3. Through the action of a firing pin l4 a cartridge disposed in the receiver l5 of the barrel H is fired. The bolt mechanism 30 is operated through a compound lever action l6 which constitutes a principal feature of the invention. The firing pin I4 is released through a trigger I1 whereby the said firing pin is caused to engage the percussion cap of the cartridge and to discharge the same. A magazine l8 holds a number of cartridges and serves to feed the cartridges into position to bedelivered to the receiver I5. In conjunction with the bolt l3 an extractor I9 is provided by means of which cartridges are removed from the receiver. Operating in conjunction with the bolt I3 is an ejector 2| which ejects the cartridges from the rifle after the cartridges have been fired and extracted from the receiver. A safety 22 holds the firing pin in cocked position preventing accidental discharge of the rifle. These various parts will now be described in detail.

The stock 10 is best shown in Fig. 1 and is constructed of wood such as walnut or any other suitable kind of wood. This stock comprises a butt 23 which is connected to a grip 24. The forestock 25 extends forwardly of the grip 24 and terminates in the forearm 26. At the end of the butt 23 is a butt plate 21 which serves as a protection for the end of the stock.

The barrel II may be constructed cylindrical in form gradually tapering toward the muzzle 28 thereof. At the opposite end of the barrel is formed the receiver I5 which is integral with the frame I2. The forestock-25 is formed with an opening or slot 29 in which the frame I2 and receiver I5 are disposed. The forearm 26 is constructed with a groove 3| in which the barrel II rests. The barrel II, receiver I5 and frame I2 being all integral, are connected to the stock in a manner to be presently described in details.

Hie bore of the barrel I I is indicated by the reference numeral 35 and extends throughout the length of the same. This bore may be rifled or otherwise constructed in the usual manner.

The receiver I5 consists of an enlargement of the barrel I I which is bored to provide a cartridge chamber 34 forming a continuation of the end of the bore 35 of the barrel II. The said chamber is further formed with a lugwell 36 in which the forward end of the bolt I3 extends and in which the bolt is locked with respect to the barrel after the cartridge has been placed within the cartridge chamber 34.

The frame I2 is disposed at the rear end of the receiver I5 and comprises two side plates 31 and 38 which are connected together at their forward ends through a cross frame member 39 integral with the receiver I5 and at their rearward ends through a yoke 48 and a tang M. This tang projects rearwardly of the frame proper and the opening 29 in the forestock 25 and is received in a recess 42 formed in the grip 24 of the stock. The frame I2 is constructed open at the top and bottom, being closed at the upper portion through the bolt housing to be presently described in detail and at the lowermost portion thereof through the lever action of the rifle. Issuing forwardly from the upper portion of the tang 4i is a forwardly extending bracket 38 which supports the trigger and sear of the invention in a manner to be subsequently described in detail.

The barrel, receiver and frame are attached to the stock III in the following manner: At the forward end of the forestock 25 is provided a screw 44 which extends through said forestock and is screwed into threads 45 formed in the receiver I5 upon the underside thereof. The head 46 of this screw is seated in a bushing 41 which is countersunk in the lower portion of the forestock 25. A similar screw 48 extends through the grip 24 and is screwed into threads 49 formed in the tang M. The head 5| of this screw is disposed within a socket 52 formed in a facing 53 extending along the curved forward portion of the grip 24 and forming a striker plate against which the operating lever of the lever action I6 rests when the various levers are in normal position. This facing is countersunk into the forward portion of the grip 24 and is partially held in position through the screw 48. A wood screw 54 extending through the facing 53 near its lower end assists in further holding the facing attached to the stock. In addition to the two screws 44 and 48 for holding the metal parts of the rifle attached to the stock, a band 55 is employed which encircles the barrel II in proximity to the forward end of the forearm 26. This band is threaded to receive a screw 56 which extends through the forearm of the stock and serves to hold the barrel rigidly attached to the stock.

The barrel II has attached to it the usual front sight 32. On the yoke 48 is mounted the receiver sight 33. These parts forming no particular feature of the invention have not been. shown in detail, though it can be readily comprehended that any suitable construction such as is now well known in the art may be used for the purpose.

v The bolt mechanism 38 of the invention is best shown in Figs. 2, 3 and 4. This bolt includes a bolt housing 58 and the bolt I3 which is of tubular form being constructed with a bore 51 extending partially throughout the length of the same. The bolt I3 is slidably mounted in the bolt housing 58 which is guided for movement in the frame I2. Bolt housing 58 is constructed with a bore 59 in which the bolt I3 is received. Bolt I3 is constructed with a shank 6| which slides within said bore 59. The shank BI is enlarged at the center of the bolt as indicated at 62 to form a shoulder 63 at the rearward end of the same. This enlarged portion slides in an enlargement 68 of the bore 59. By means of this construction axial movement of the bolt I3 in the housing 58 is limited.

The housing 58 18 best shown in Fig. 5, is constructed with two laterally extending wings 69 and I8 which are formed with outwardly projecting tongues 64 and 65 at the sides of the same. These tongues are received in grooves 66 and 6! formed in the upper portions of the side plates 31 and 38 of frame I2. By means of this construction the housing 58 is held from rotation and guided for reciprocating movement in a direction parallel v to the bore 35 of the barrel II For locking the bolt I3 in the receiver I5 a construction best shown in Figs. 2, 3 and 10 is employed. At the forward end of the bolt I3 is formed a head 88 which is constructed with two outwardly extending diam etrally opposed locking lugs II and I2. The bore of the lugwell 36 is of sumcient diameter to receive the head 68 and the two lug's II and I2 and to permit rotation of the same within said chamber. In the end of the receiver I5 is formed a transversely extending opening which is of a height slightly larger than the width of the lugs II and I2 and of a width suflicient to permit of the insertion of the head with the lugs into the lugwell 36. By means of this construction two portions I3 and I4 are formed which serve as cams for engagement with the two locking lugs II and I2. The lugs II and I2 are formed with helical surfaces I5 which cooperate with similar surfaces 16 on the cams I3 and I4. When the bolt I3 is rotated the surfaces 15 and I6 force the bolt inwardly toward the cartridge chamber 34 in a manner to hold the head of the bolt snugly against the end of the cartridge.

Rotation of the bolt I3 for the purpose of locking the same within the receiver I5 is accomplished by sliding of the bolt housing 58. For this purpose the enlarged portion 68 of the bore 59 of said housing is constructed with two helical grooves 11 and I8, Figs. 5 and 9. Two guide lugs I9 formed on the enlarged portion 62 of bolt I3 are received within these grooves and cause rotation of said bolt when the bolt housing is slid relative to the bolt. At the forward ends of the grooves 11 and 18 the same are constructed radial instead of helical, as shown in Fig. 9 and designated at 8|. This is for the purpose of locking the bolt against endwise movement relative to the bolt housing when it is desired to reciprocate the bolt after the same has been unlocked. The bolt I3 is held in a position within the housing 58 by means of a collar 82 which is received in a recess 83 in the end of said bolt housing and held in position therein through a set screw 84.

In order to move the lugs 19 out of the circumferential portions M ofthe slots 11 and 18, the two locking lugs II and 12 are provided with helical edges I16. These helical edges engage corresponding helical edges I11 on the earns 13 and 14. When the lugs are entering into the lug well 36 the bolt is rotated through the said cams and into a position where the said lugs 19 may enter the helical portions of the grooves 11 and 18 to permit of rotation of the bolt as previously described. Further movement of the bolt housing causes rotation of the bolt and the locking of the bolt within the receiver I5.

I said firing pin is a cocking piece 92.

slide along said bore 51.

Discharge of the cartridge is procured through the firing pin I4 which is shown in detail in Fig. 4. This firing pin is of lesser diameter than the bore 51 of bolt I3 and is constructed near its forward end with a collar 86 of proper diameter to The firing pin I4 is further guided for sliding movement within the bore 51 in a bushing 81 which is. screwed into the rear end of bolt I3. A compression coil spring 88 is disposed within the ,bore 51 and encircles the firing pin l4. This coil spring is seated at one end against the bushing 81 and at its other end against the collar 86. This spring serves to urge the firing pin toward the cartridge. On the end of the firing pin is provided the usual striker 89 which is adapted to enter an opening 9| in the end of the head 68 of bolt I3 and to strike the percussion cap-of the cartridge 28.

The firing pin I4 is held cocked through the following construction: Secured to the end of This cocking piece is formed with a catch 93 on the underside thereof adapted to be engaged by a sear 94. gear 94 is disposed within a case 96 attached to the bracket 38. !The case 96 is constructed with side walls 91 and 98, Fig. 6, and with front and rear walls 99 and I88. The two walls 91 and 98 are provided with outwardly extending flanges I 8| and I82 which are secured to the bracket 38 through rivets I83. In this manner the case 96 is attached to the frame of the rifle and mounted with its walls 91 and 98 spaced'from the side plates 31 and 38 of frame I2. The sear 94 is pivoted on a pin 95 which extends through the two walls 91 and 98 of case 96. The trigger I1 is disposed within the case 96 and is pivoted on a pin I84 which passes through said trigger and the two plates 91 and 98 of case 96. This trigger is constructed with a rearwardly extending portion I85 and with a finger piece I86 depending therefrom. A link I81 is pivoted to the portion I85 of trigger I1 through a pin I88. This link extends upwardly and is further pivoted to an arm I89 formed on the sear 94 by means of another pin III. By means of this construction the sear 94 is moved in a direction to disengage from the catch 93 when the finger piece I86 of trigger I1 is moved rearwardly. For the purpose of urging the finger piece I86 of trigger I1 forwardly and the sear 94 upwardly, a compression coil spring H2 is employed. It will be noted that the pin 95 on which the sear 94 is pivoted is disposed rearwardly of the pivot I 84 of trigger I1. Spring H2 is situated forwardly of pin 95 and rearwardly of pin I84 being seated in sockets H3 and. H4 formed in said sear and trigger. By means of this construction the single spring H2 causes both parts to function in the proper manner. The movement of the finger piece I86 of trigger I1 is limited by a pin H5 which extends through the two walls 91 and 98 of the case 96. This pin engages a projecting part H6 on the trigger I1 which terminates the movement thereof when the trigger is in the position shown in Fig. 4. Movement of the finger piece I86 of trigger I1 rearwardly as previously described, swings the sear 98 in a manner to disengage the same from the catch 93 of cocking piece 92, permitting the firing pin I4 to be forced forwardly through spring 88 and to cause the striker 89 to strike the percussion cap of the cartridge 28.

For the purpose of operating the bolt, my improved lever action is employed, which has been indicated in its entirety by the reference numeral I6. This lever action is compound and includes a speed lever H1 and a power lever H8. The power lever H8 is pivoted on a pin H9 which passes through the two plates 31 and 38 of the frame I2. Lever I I8 is constructed with a pair of rearwardly extending spaced arms I2I and I22 (Fig. 5) which are connected together by a bridge I23. The bridge I23 formed at its'forward end with a boss I24 which receives the pin H9. The said lever is further constructed with two spaced upwardly extending arms I25 and I26 which are disposed in the same plane as the arms I2I and I22. The two arms I25 and I26 fit in between the two side plates 31 and 38 of frame I2 lying close to the inner surface thereof. Lever H1 is disposed between the two arms I2I and I22 and is pivoted to the ends thereof through a. pin I21 which extends jointly through said arms and lever. Lever H1 is constructed similar to lever H8 and is formed with two forwardly extending spaced arms I28 and I29 which are connected together by a connecting portion I3 I. The two arms I28 and I29 straddle the .case 96 and are themselves straddled by the two arms I25 and I 26 of lever H8. The lever H1 is further constructed with a rearwardly extending portion I32 which forms a trigger guard for guarding the finger piece I86 of trigger I1. The rearward end of this trigger guard is provided with a loop I33 which serves as a handle for swinging the lever action of the invention. This loop when the lever is in normal position lies along the facing 53 and is .disposed as shown in Fig. l. The free ends of the arms I28 and I29 of lever H1 are constructed with cylindrical heads I34 which are adapted to engage in vertical slots I35 formed in the two wings 69 and 18 of the bolt housing 58. Similar heads I38 are formed on the upper ends of the arms I25 and I26 of lever H8 which are also adapted to engage the same slots I35. These heads slide along the said slots and serve to reciprocate the bolt housing when the lever action is operated. The arms I28 and I29 of lever H1 are guided for movement by pins I38 which are attached thereto and which travel in grooves I31 formed in the side walls 31 and 38 of the frame I2.

The action I6 operates in the following manner: When the levers H1 and H8 are disposed as shown in Fig. 4, bolt I3 is in locked position, the two lugs H and 12 thereof being substantially vertical and locked in front of the earns 13 and 14. In this position the heads I38 of lever H8 are received within the slots I35 and the heads I34 of lever I I1 are considerably below the bolt I3. In cocking the gun, lever H1 is moved downwardly through the loop I33. As the said lever is pivoted to lever H8, lever H8 is swung about the pin H9 as a pivot and moved to the position shown in Fig. 7. Due to the fact that the pin I36 when at the end of the groove I31 is substantially in alignment with the two pins I 21 and H9 the said pin forms a fulcrum for swinging the lever H1, which causes the force imparted to said lever H1 to be transmitted to the lever IIB. Arms I25 and I26 being relatively short as compared to the combined length of the arms I2I and I22 and the trigger guard I32 and loop I33 has appreciable leverage and considerabie force is exerted upon the bolt 38 through such movement of the lever action which causes the bolt housing to slide axially with respect to the bolt proper I3. During such movement the two lugs 19 on the bolt slide in the grooves TI and I8 and cause the bolt to rotate. These grooves being spiralled in the proper direction cause the two lugs II and I2 to become disengaged from the respective cams I4 and 13 and to. occupy the position shown in Fig. 7. When this occurs the two lugs 19 are at the beginning of the portions 8I of said grooves. Further movement of the bolt housing causes rotation of the bolt through the action of the cam surfaces I11 and I I6 which moves the lugs I9 into the portions 8| of grooves 11 and I8. When the said lugs reach such position rotary movement of the bolt ceases and further axial movement of the housing 58 causes a corresponding axial movement of the bolt. While the levers I24 and I25 have moved the housing 58 from the position shown in Fig. 4 to that shown in Fig. 7 for the purpose of unlocking bolt I3, the levers I28 and I29 move upwardly until the heads I34 on said levers are brought into the slots I35. In the position shown in Fig. 7, heads I38 are about to be swung downwardly with respect to the bolt housing 58 and to become disengaged from the slots I35. As this occurs, the heads I34 are brought into engagement with said slots and the movement of the bolt housing 58 continues. When heads I38 are free from the bolt housing, lever III operates solely to move the bolt housing axially. During such movement the arms I2I and I22 of lever .II8 merely serve as links providing a. floating fulcrum for the lever II'I. During further movement of the bolt housing the heads I34 are maintained in proper position in the slots I35 through the grooves I31 and pins I36 so that proper operation of the device results. By inv spection of the drawings it will be found that approximately one to five and one-half lever advantage is procured while the heads I38 are engaged within the slots I35 and that approximately one to one leverage is procured when heads I 34 are in said slots. After the bolt has been unlocked from the lugwell it requires very little force to move the same and the one to one leverage procures rapid movement of the bolt throughout the remainder of the travel thereof. When the bolt and bolt housing, are fully retracted the parts are disposed as shown in Fig. 8. It will be noted that the travel of the bolt is sufllciently short relative to the gun proper so as to keep the bolt housing from striking the marksmans face when the lever is operated.

In addition to the cartridge 28 which isdisposed in the cartridge chamber 34 of the barrel of the rifle a number of other cartridges 20a and 20b may be kept which are contained within the magazine I8 previously referred to and which are fed one at a time into the receiver as the cartridges are fired and ejected. The magazine I8 in which these cartridges are contained, is a rectangular box-like structure having end walls MI and I42 and side walls I43 and I44. These walls are connected together through a floor plate I45 which closes the lowermost portion of the magazine. The magazine is attached to and supported between the two side plates 31 and 38 of the frame I2. For this purpose a rearwardly extending flange I46 is formed on the upper portion of the end wall I4I which flange rests upon and is secured to the bracket 38 by screws I 41. The forward portion of the floor plate I45 of said magazine rests upon a ledge I48 which issues rearwardly from the cross frame member 39. A screw I49 passes through this ledge and is threaded into the floor plate I45. The magazine I 8' is of a width somewhat greater than the width of one cartridge so that the said cartridges may be arranged within said magazine as shown in Fig. 5. In the particular rifle illustrated the magazine is sufliciently large to receive and hold three cartridges, two of which have been shown in the drawings. In the magazine I8 is provided a follower I 5| which is attached to a Z-shaped leaf spring I52. This spring is in turn secured to the floor plate I 45. By means of this spring the follower I5I is urged upwardly and tilted to feed the cartridges upwardly in a manner to permit of inserting the same into the cartridge chamber 34 of the rifle. The follower plate I5I is provided with an abutment I53 against which the lowermost cartridge 20b rests and by means of which cartridge 20b is urged toward the wall I44 of the magazine. At the upper ends of the walls I43 and I44 are formed inwardly turned lips I54 and I55. The cartridge 28a when the bolt clears the same in its retracted position is urged against the lip I54 by the cartridge 2% and is held in such position through said lip. When the third cartridge is in the magazine the same is held against the lip I55 in the same manner. Also cartridge 28b when cartridge 25a has been fired is similarly held against lip I55. When the bolt housing 58 is in the position shown in Fig. 4 the lowermost portion thereof engages the cartridge 20a and holds the same below the lip I54 as shown in Fig. 5. When the bolt housing 58 is in the position shown in Fig. 8, the cartridge is free to raise until the same engages the lip I54. In such position the bullet of the cartridge which is smaller in diameter than the shell tilts upwardly until the same is above a bevel I56 formed on the wall I42 of magazine I8 and the cross member 39 of the frame I2. At the same time the center of the bullet is brought in alignment with the medial plane of the rifle. This is accomplished by the particular construction of the lips I 54 and I55 which slightly converge. At such time the uppermost portion of the base I58 of the cartridge is in line to be engaged by the lowermost comer I58 of head 68 of bolt I3. As the bolt I3 travels forwardly, said head raises the cartridge along the beveled surface I56 anddirects the same through the lugwell 35 and into the cartridge chamber 34 in receiver I5. As the cartridges are drawn from the magazine the bolt housing 58 covers the magazine and holds the succeeding cartridge in position therein. Further operation of the bolt causes repeated action, bringing about the successive feeding of cartridges into the receiver as the same are discharged and extracted.

The extractor I9 is best shown in Figs. 2, 3 and 5. In the bolt housing 58 is formed a T-shaped slot I6I. A T-shaped bar I62 is slidably mounted in this slot. "This bar is formed at the forward end of the same with a finger I63 which is adapted to engage in the groove I64 01' the cartridge 28. When the cartridge is moved upwardly in being transferred from the magazine to the receiver the same automatically is brought into engagement with the finger 63 and so remains during the firing of the cartridge. The bar I62 is held from longitudinal movement with respect to the bolt I3 by means of a radially extending key I65 which is adapted to engage into a circumferential slot I66 in the head 68 of bolt I3, which slot is situated adjacent the locking lug 12. This construction permits of turning the bolt without turning the extractor and at the same time restrains relative longitudinal movement therebetween. When the bolt I3 is retracted, key I65 draws the extractor with it causing the finger I63 to withdraw the empty cartridge through engagement with the base I58 of the same.

The ejector 2I is in the nature of a swinging lever which is received within a slot I61 milled in the side plate 31 of frame I2. This ejector is pivoted, on a pin I1I mounted in the upper portion of the said side plate. Ejector 2| is formed with an engaging finger I68 which is urged toward the position shown in Fig. 2 by a compression coil spring I69. When the bolt I3 is moved rearwardly the rear corner I12 of locking lug 1I engages an arm I13 formed on the rearward end of ejector 2I and forces theejector inwardly toward the cartridge. Said lug is constructed with a cavity I14 into which the finger I68 may extend. Upon continued movement of the bolt I3, said finger is caused to engage the base I58 of the cartridge and to throw the shell laterally out of the rifle through an opening I15 in the side plate 38 of the frame I2. When the bolt is moved in the opposite direction, pressure on the lever I13 is released and the ejector 2I again occupies the position shown in Fig. 2. The position of the bolt and the ejector when the bolt is in its extreme retracted position is shown in Fig. 3. In this position the cartridge has been completely ejected from the rifle.

The rifle A may be provided with a safety by means of which the firing pin I4 is held cocked. This safety consists of a transversely disposed spindle I18, Fig. 6, which is rotatably supported in a bore I19 in a bushing I8I formed at the rearward portion of the bolt housing 58. Spindle I18 terminates at one end in a finger piece I88 by means of which the same may be rotated. The spindle I18 is constructed throughout the major portion thereof semi-circular in cross section and is adapted to engage in two round notches I8I and I82. Notch I8I is formed in part I83 integral with the yoke 40 of frame I2 while the notch I82 is formed in the cocking piece 92. When the safety is in the position shown in Fig. 4 the parts may move with respect to one another and the rifle functions in the ordinary manner. When the safety is turned through an angle of 180 degrees the rounded part of the spindle I18 enters the respective notches I8I and I82 and holds the parts locked, but still permitting operation of bolt and housing with the lever action for the purpose of emptying the magazine.

In order to remove the bolt and bolt housing from the rifle, a construction is employed which is best shown in Figs. 8, 11 and 12. Grooves I31 are formed at their rearward ends with downwardly extending branch grooves I85. In the side plate 38 is formed a T-shaped slot I86 which intersects the groove I31 in said side plate. A T- shaped locking bar I81 is slidably mounted in this slot and is provided at its forward end with a finger I88 which forms a continuation of the lower edge of groove I31 and which holds the pin I36 within said groove. When the bar I81 is slid toward the left as viewed in Fig. 8, the pin I36 is unlatched and may travel up and down in the branch groove I86. When pin I36 is at the bottom of groove I86 and bar I81 disposed at the right hand end of slot I86, the finger I88 holds said pin latched in such position. When the parts are so disposed the heads I34 are disengaged from slots I35 and the bolt housing and bolt may be completely removed from the rifle. When the bar I81 is in-such position and the pin I36 is at the upper end of groove I86, said pin is free to travel along groove I31 and the lever action is free to function normally. The bar I81 is urged toward the branch groove I86 by means of a compression coil spring I99. This spring is retained within a hole I 9| (Fig. 12) drilled in the end of said bar and engages the side plate 38 of frame I2 at the end of the slot I86. Bar I81 is moved against the action of spring I98 by means of a finger piece I92 which is attached to said bar by a machine screw I93. Finger piece I92 operates in a slot in the stock III which is protected by an escutcheon I 94. It will be noted in Fig. 11 that said finger piece does not extend beyond the surface of the stock I0 so that the same cannot be accidentally manipulated.

My invention is highly advantageous in that a simple and practical lever action is provided which may be used in conjunction with bolt locking type rifles. The action is so constructed as to procure maximum power for the purpose of locking and unlocking the bolt and extracting the cartridge from the receiver and maximum movement during ejection of the cartridge and replacement of the next cartridge. My invention gives all of the advantages of both the bolt type and lever action guns permitting the cartridge to be rapidliy ejected and replaced and at the same time giving the rigid backing to the cartridge only possible with the bolt type gun. With my gun any of the highest powered cartridges may be used, which is not possible with previous lever action guns.
