300 BO is not a tack driver, but you can get decent accuracy. With the 311410 with a gas check I can get under 2 MOA 5 shot groups at 100 yards benched, and under 4 without trying too hard for over 15 rounds. This is at almost 2200 FPS with a 130 grain H/P boolit. Still working on that load to see if I can get it down further. This is with ASBB tumble powder coating.
