cant find any of th old percussion primed 20mm ammo. this stuff is around korean war vintage but have a use for it. used to be at the gun show but havent seen any inquite some time. if i could locate some for the right price and location, would definitely be a buyer. needs to be in the louisianna, texas, new mexico, arizona area. must verify where you got it before i buy. dont want anything to do with stolen ammo from some guard armory. if i can find some will break out one of my old toys and start blasting.
