I have a buddy that asked me if i wanted to buy a rifle from him....its a safe queen. its a marlin bolt action .17 mach 2 , ive heard and read up on it, but i wonder if any real world users shoot it on a regular basis. I have over 1k 22lr left over from when my guns were stolen about 3yrs ago. Is it worth it, or sticking with the tried and true .22 be better?
