RE: If I could do it over again.
I, like many here, have had a variety. Most just sat in the safe, while I used one or two "favorites" most of the time. When I moved, a while ago, I decided to cull my "collection". I now have just ONE rifle (.308 bolt-action) and ONE shotgun (12 guage). I am happy with this simplified arrangement. I have enjoyed each of my guns - each for slightly different reasons. If I had it to do all over again, though, I would probably not have aquired so many - and used the money for other things. "To each his own", though.
