CARTRIDGE FOR A SLIPPED SPORTS AND HUNTING WEAPON WITH A LEAD FREE BULLET

摘要

The utility model relates to cartridges for a rifled sport and hunting weapon with a lead-free bullet having a shell and core made of a composite material exhibiting properties similar to those of lead, but not endangering the environment. The objective of the proposed solution is to create a cartridge for a rifled sport and hunting weapon with a lead-free bullet and having ballistic characteristics similar to a lead pool, but not harmful to the environment. In the process of solving the problem, a technical result is achieved, which consists in increasing the manufacturability of the manufacture of the cartridge and reducing its cost in the manufacture. The technical result is achieved by a cartridge for a rifled sports and hunting weapon with a lead-free bullet, consisting of a sleeve with a capsule, a bullet and a propellant powder charge, while the bullet has a bimetallic shell and a core of length (2.6-4.2) d having a head and tail parts , the head part is made in the form of living, with a length of (0.8-2.3) d, with a flat platform with a diameter of (0.1-0.5) d in the upper part, and the tail part consists of a cylindrical part with a diameter of (0.72 -0.86) d, and a truncated cone with a height of (0.1-1.0) d, where d is the bullet caliber, mm, the smaller diameter of the cone and equal to (0.8-0.99) the diameter of the cylindrical part, the core is made of a composite material consisting of spheroids with a diameter of (0.2-2.0) mm and a density in the range of 9.0-13.5 g / cm polyurethane, the basis of the material of the spheroids is the diamond grinding slurry of products from tungsten-cobalt alloys with a cobalt content of (3-15)%. In addition, the mass of sludge in the material of the core spheroids is at least 90%, the rest is carbon, phosphorus and metal impurities from the group of tin, zinc, aluminum, iron, copper, bismuth and their mixtures, the core spheroids are sintered.
