Is this barrel going to be a big difference accuracy wise? more so with a match chamber? would a sport chamber offer less accuracy but more reliability? Learning new stuff here....I'm all spongy  |
Good grief... my first thought is "gimme a break!!!".
But then... If you want to shoot expensive match ammo for bench rested groups the match chamber with the ammo it likes best should give best accuracy. Will it in a polymer gun? I dunno.
What I do know is I have (pistols) Ruger 22/45 Lites and and 2 VQ Scorpions. The VQ's are a 6" with a match chamber and a 4 1/2" with a sport chamber. I started shooting the pistol part of rimfire challenge with the Rugers and have switched to the 4 1/2" VQ.
The Rugers have the biggest chamber. They also shoot the worst. With the ammo I usually shoot I'm not sure I can find an accuracy difference between the sport and match chambered VQ LLV (Scorpion) uppers. I can tell a difference in how they run. I have to run different recoil springs to get reliable function. The Rugers with their looser chambers get the stiffest recoil springs. The sport chambered VQ a step lighter and the match chambered VQ upper gets one a further step lighter. You walk a fine line on the pistols getting their bolts to run full cycle distance but not beating up the bolt stop and frame. The tighter chambers are more finicky. If I wanted to use the 6" match chambered VQ upper for speed shooting like steel matches I'd ream the chamber.
How will the trick 15-22 VQ barrel work? We'll see. I certainly expect they'll shoot better but their lighter weight was what I'm after.
