Armsel Striker

Tungsten alloy shot is used as the shot for shotgun hunting shells. The pellets spread upon leaving the barrel, and the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is fairly low. Tungsten alloy shot can be used for Armsel Striker.

The Armsel Striker — also known as Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog, and Cobray/SWD Street Sweeper — is a revolver 12-gauge shotgun designed for riot control and combat.

The weapon's action is similar to that of a revolver, using a rotating magazine. Since the Striker uses a more or less conventional double action only trigger, and a very large and heavy cylinder (compared to handguns), Walker added a pre-wound clock-work spring to revolve the magazine. This proved to be a slow and ineffective way to load the weapon. The design was changed so that there is now a cocking lever on the right side of the barrel.
