I got a used 10/22, a new Victor stock and GM barrel and got sub .5" for 5 shots at 50 yards w SK rifle match ammo.
Repeatably.
Had less than 500 bucks in that gun.
Was a few years back though.
Wanted .5 for under 500 (not counting scope).
Got it and was bored, as the Victor stock grip angle was NOT comfortable for me off the bench...........and I wanted the gun as a hunter.
My CZ457 is just the American model. And its .22 mag. Trigger is heavy. Haven't done anything to it but put on a scope and shoot maybe a dozen shots to zero it
at 50 yards. It shot well. On the way back from the range I stopped at a bean field, walked to corner and shot a big boar groundhog standing, in the neck.
Shot was 60 yards, offhand, scope set at 6X. Bullet hit right where aimed.
Yeah, guess I gotta keep it. LOL
Ive thought about another CZ sporter in .22lr, get rid of my big heavy Savage.
But I really want an Anschutz 64 as I rarely hunt w .22 lr and had a couple 64s back in the day.
A better than average .22 lr collecting dust is still a better than average .22 lr
