the smooth surface allows projectiles to move quickly down the length of the barrel. Smooth-bore barrels are well-suited for firing multiple projectiles at the same time. On the other hand, rifled-bore weapons fire a single projectile. The interior of the barrel has spiraling grooves...
bore to a depth of a predetermined dimension, the rifled-bore section (12) having a length corresponding substantially to the peak pressure point for the gun barrel, the smooth-bore section (14) comprising a second generally tubular body having a longitudinal bore coaxial with the longitudinal ...
1, comprises a barrel extension 10 having a bore 13 which is rifled at 14 and means for securing the extension 10 on the barrel 11. The securing means includes a collar portion 15 having wings 16, 17 and screws 19, Fig. 2, which extend through the wing 16 into screw-threaded ...

the smooth-bore section comprising a second generally tubular body having a longitudinal bore coaxial with the longitudinal bore of the rifled-bore section, and the longitudinal bore of the smooth-bore section having a diameter greater than the diameter of the bore of the rifled- bore section and...
Disclosed is a bullet shell for hunting guns, preferably those having barrels with "rifled choke" rifling. The shell comprises a bullet made of a solid material and a thin-wall plastic envelope. On its surface, the bullet has a trapezoidal groove delimiting nose and heel portions of the ...

Cartridge for a smooth-bore gun in which the shot is to be replaced by a bullet with a lead body and a steel point includes a non-metallic cylinder with external rifles which impose a rotation to the bullet as it passes the choke near the muzzle end. This cylinder is enclosed in a ...
FIELD: weapons.;SUBSTANCE: invention relates to the field of firearms, in particular to the production of projectiles (bullets) intended for destruction of light armoured targets. Technical result is achieved by the fact that a double-shell armour-piercing bullet for a rifled and smooth-bore ...
