Shot the 220gn round nose the other day. Pushed by 9.6gns of LIL Gun, 3 rounds grouped 0.19" at 50yds off of a bipod and rear bag. I do not have chrono data yet, but will update when I do. They seem to be right on the edge of subsonic. Not quite as quiet as the Silencerco 220 smk sub load, but plenty quiet. For the accuracy they are producing, I will happily trade that for a tiny bit of noise. Still well within the realm of hearing safe with my SAS Arbiter. These are through the Ruger Ranch 16" 7tw.
