Hey everyone. Only my second post. I recently bought a used Mini 30 and it is very clean and the action works nicely. I also got some 3K 10 rnd mags. I took it out for the first time today and the bolt wasnt feeding the rounds in correctly. The bolt would miss the rim and slide half way up the case and jam up. I thought it might be the mag, but I tried again with the factory 5 rnd mag and had the same problem. Any suggestions as to what the problem might be?
