Got my Mossberg 590 Mariner, went shooting, small problem...

This thread may turn useless now as it turns into a mossy versus remmy debate. AGAIN :banghead:

Not sure on the Mossberg's but I have had similar problems with Remington's and I had to polish the chamber (fired/swollen shells).

I suspect the biggest problem is with rough chambers (from marine coat, dull chrome, applied coatings, etc), tight tolerances and the steel/aluminum head "bargain" shells.

some of the cheap Winchester low base shells visibly expand and like to stick in my chamber sometimes. i dissected a few of the culprit rounds and noticed the plastic hull was noticeably thinner in those, causing them to swell.

Polish the living hell out of the chamber with a dremel and then try it.
