I've had this 10/22 for a few years now, and have been relatively happy with it for gophers, offhand mostly. But, I just went out to the range and can't get a decent group at 50 yards, or even 25. Right out of the box I had the trigger components replaced, butler creek composite stock, butler creek fake carbon fibre barrel, and Simmons .22mag scope. I know, I know, the barrel is crap, right? But, my question is, if I change the barrel, will my groups improve a lot? Also, I've always hated the Simmons 3-9 .22mag scope, what do you guys suggest for a decent alternative. (I have a Mueller on my .17 and it seems great so far, but I'm looking for suggestions).
