Thanks for the reply Planetcat. I do reload, but any new gun I get I always run about 500 rounds factory through it before I use any reloads (that gives me brass). I am shooting Fusion & PPU 168 gr fmj's. Their length is 3.340. They both jam after firing, ejecting and jam on the reseat. All my Remington's are soft point, which measure 3.20 and do not jam at all. All my reloads are going thru my ruger American right now. For future reference, what is a better forum to post in. And thanks again. And again. If I take my fmj's to 3.2 overall length, they do not jam.
