Here's the deal. Me and a friend went shooting a month ago. He brought his M44 mosin Nagant and I brought my M1 and my two Enfields. We were shooting and he wanted to shoot my Enfield. So he loaded the magazine and started firing. After the 3rd or 4th round he shot and there was an earringing bang he went to eject the round and the rim with the primer, basically the entire bottom of the case tore off. He then told me when he pushed the bolt forward to lock in the round it took a bit more forcing. So now I have a 1942 Enfield with a Russian brass stuck in it. How (if at all possible) can I remove it?
