I wish I had more 9mm and 38 special. I have what some would consider plenty, but can there ever be too much?
I could probably do with less 7.62x54r. When I noticed prices going up on it I picked it up whenever I found a deal. I have more than I'll ever use, mostly because I never shoot it. I have a few mosins but they've never been brought out. I bet they're fun though.
Grab one of those Mosins, and c'mon out to OKCGC the first Sunday of the month, shoot in the Military Bolt-gun match.
Lots o fun, cheap entertainment.
