RE: mosin nagant
I did own one for several years but the bore was not in the best of shape. I think they would be fun to own from the standpoint of having a piece of history, but I would not set my expectations very high unless you find a sniper model. Norma used to make some decent ammo for them. The rifle was at least good enough to help win WWII. Get a late model though, one built for smokeless powder.
