my wifes 10/22 sports the BC 20" barrel and it is very accurate with cci 40gr minimags and many other ammo types - both 36 and 40 grainers. It actually is a tad more consistant than my Green Mountain barrel which is more finicky. I am very pleasantly surprised that it is as good as it is. I had read that they were hit and miss but this one is definately a hit.
Dont have any experience with the shooter ridge barrel.
I have a buddy running a 20" Dlask barrel and it is a shooter as well. good pricing. I will be putting a 16" Dlask fluted on my current rig for comparison against my current 16" GM fluted barrel
