This is a very complex 12ga. shotgun slug design. They MIGHT be called Polev-7, though that isn't certain. With a three-piece sabot, and a very small and relatively light projectile, these are fast-moving rounds. We show a few problems, which I believe is due to the snug fit between the gas piston and the projectile, that caused ballistic issues. Luckily this didn't occur on all the shots.
