This is my 1st time shooting this brand. I have a 1:10 twist 20" barrel. I did not have the chrono out but at 96 yards (ranged), I was keeping (.6" groups) consistently except when I pulled a shot and called it. My dad's rifle has a 22" barrel and I believe a 1:12 twist was keeping right around a (.75" group). Very pleased as all shooting was done off a bipod laying prone with a fair amount of wind (14mph with gusts of 22mph).
