A 577 cal P53 Enfield Artillery (Rifle) Carbine, a 577 P53 Enfield Rifle Musket and a US M 1863 TII Rifle Musket. Both the British designed and built p53s shoot 57 caliber pure lead Minie's over about 60 gr of FFg BP. They will shoot almost as tight a group as the US rifle muskets I have- particularly the P53 carbine, yet another surprise! The US M 1863 shoots a 58 caliber pure lead Minie' also over about 60 gr of FFg BP. I'll include pics of the P53s and the US M 1863 w/target.
