Here's 22 Rounds of federal 180, at 25 yards, after sight in
Completely stock. I got the stock extension, but not in time for the range. My plan it to get the Tacticool three pack and go from there. I often shoot my S2K-40, but always with the stock extension or butt pad.850
With regard to the recoil are you shooting your 2k stock, with buffer, a heavy brass bolt and/or a sumo handle?
