Hoplite,
9mm, 38 and 40 and 45 cal are all on sale, the sale circular just said Winchester centerfire. (I don't think 30 30 or 30 06 was listed.) I had problems with the
winchester shotshells. (Aluminum based, made in France, and I broke an extractor hook on my Mossberg 500 forcing the pump back to try to get a stuck one out. Right after that, my friend had one stick the same way so we decided enough clays, on to pistol and rifle.
T and T fixed it free (it was just 6 months old) and I vowed never to buyaluminum based shotshells again. A guy on guntalk.com and another on Numrich arm's website both confirmed they also had Win aluminum shells stick in their shotguns too. Autoloaders might be OK, but be careful once the shotgun gets "warm."
