Armor piercing shotgun shell. Its a finned lead body with a hardened steel penetrator rod in the middle. Its said these can penetrate 1/4" steel plate? Its been a hobby of mine to slowly collect as many variations of shotgun ammo I can legally buy just for fun. I will never use them. I buy them just as a novelty...unless the SHTF of course because they are so DAMN expensive!!! I have about 8 different rounds so far. If I could just get my hands on those fin stabilized HE rounds I saw on discovery channel!!! Wanna kill these ads? We can help!
