My Ruger factory 10/22 ss 20"? shoots only a smidge better than the 3 std carbine barrels Ive tried. I expect the generous field chamber is the biggest issue, a CPC barrel job would likely help.
Never tried one of the Ruger hammered barrels, each one Ive looked at is too rough an exterior for my tastes. I know I could fix that but for the prices asked, no.........
Have a Shaw with a better/tighter chamber, it is a bit touchy on keeping clean (not really a big deal) for best function, still carbine length, no sight so scope only, and it doesnt shoot the magic groups.
Looks wise I like the long ss that I dropped the sight and installed a blacked 'flash hider' (lol) just for the extra length and color contrast of the Dragunov style build. I did shoot it before and after the F.H., no dif I could detect. Lucky me.
