In the case of steel core projectiles, as they are mainly used for military purposes, the Attachment of the steel core in the guide jacket of the projectile certain difficulties. It is here required to center the projectile core exactly and at the same time free of play with the outer jacket of the To connect floor.

It is known to store projectiles in the case mouth of the cartridge elastically in that from plastic deformable material, e.g. B. lead, formed shear body can be used. Such bodies are partial on the projectile plug, partly housed in the projectile space of the cartridge case.

In order to fasten the projectile core in the projectile casing, intermediate layers or inlays have been used so far made of lead used. Inlays made of aluminum or brass alloys have also become known. The intermediate layers made of lead ensure a firm fit of the bullet. However, they are in production difficult to handle because of the easy deformability of the lead. Inlays made of aluminum or other metallic materials have the disadvantage that a backlash-free and firm version of the projectile core cannot be achieved with sufficient certainty. With all known deposits, the Position of the core in relation to the cladding not fixed.

The invention consists in that an intermediate layer consists of plastic and from the top of the Steel core is perforated, the point being centered in the throat of the jacket. The liner made of plastic is easier to handle in the loading machines due to its greater elasticity. About that In addition, this intermediate shirt made of plastic has the advantage of low weight, which some Special loads is important.

The intermediate layer can be made of polyethylene, polyvinyl chloride, polystyrene, polyamide, phenolic resin, epoxy resin, Polyester and other plastics are made.

Steel core bullet

Applicant:

Dynamit Nobel Aktiengesellschaft,
Troisdorf (district of Cologne)

Reinhold Rapp, Stadeln near Fürth (Bay.),
has been named as the inventor

Instead of a plastic shirt that envelops the core over its entire length, inserts can also be used can be used with only partial coverage.

The drawing shows an example of such a steel core bullet. The bullet 1 sits in the neck 2 the cartridge case and consists of the steel jacket 3 and the core 4 made of hardened steel. Between core and the sheath is the plastic intermediate layer 5, the tip 6 of the core being the plastic intermediate layer penetrates. The tip is centered in the throat 7 of the jacket 3.
