Improved shotgun ammunition providing improved guidance for a large range of different barrel diameters without the use of plastic wads that separate the metal of the projectile from the barrel, while decreasing the stress for the barrel material, providing the greatest possible expansion of the projectile during impact on soft targets.

Improved shotgun ammunition providing improved guidance for a large range of different barrel diameters without the use of plastic wads that separate the metal of the projectile from the barrel, while decreasing the stress for the barrel material, providing the greatest possible expansion of the projectile during impact on soft targets.

Described are spherical projectiles such as used in birdshot, buckshot, or single ball spherical projectiles, including slugs, muzzle loading projectiles, or any close-to-bore diameter projectile, that is auto-segmenting or self-segmenting upon impact with a target. The projectile or shot disclosed herein retains its shape and structure during flight until impact with soft tissue, whereupon its individual sections separate or segment in a controllable manner, each portion of the projectile imparting or depositing a high amount energy to the tissue and target. The auto-segmenting spherical projectiles can be frangible or non-frangible. This disclosure also provides cartridges such as shotshells that are loaded with the projectiles described herein.

The invention relates to ammunition for firearms, as smooth and a rifled barrel. The projectile with rigid attached to the housing stabilizing fletching block, plates of fletching block have a continuation on the housing, centering the projectile in the barrel. In the offered variant, on the friction and heat of the bullet and the barrel takes about 1% of the shot energy, besides low vibration. The rest of energy escapes to destination, and that's good. Erasing minimal of the barrel. Application of the projectile in the shotgun and rifle barrels increases the service life of barrels. Use of such projectiles increases the initial speed, and with the sleeve-nozzle and a second charge, allows to increase the speed and specialization of the projectile. At the expense of the aerodynamic and gyroscopic effects, increases the lethal effect over long distances, due to the greater energy saved, improve the close grouping of shots and flat trajectory.

A .45-70 shotshell is made using a .45-70 shotshell base and a .410 shotshell hull. The hull is received and retained in the shotshell base. The shotshell base may be formed from a .45-70 rifle cartridge.
