Just put 100 Winchester Varmint HE 25 grain rounds (2600 fps) thru my new B-Mag. Before shooting I adjusted the Accu trigger to 2.5 lbs. Just a little creep at take-up; crisp 2.5 lbs after that. Sighted in at 100 yards. Average group size of 1 inch or less. 2 malfunctions - one failure to eject and one light dimple from the firing pin. Rotary magazine loads easily and functioned without a hitch. Good shooting little rifle! I wasn't impressed when I handled the gun at the shot show. I am now... Waiting to get my hands on some of the 3000 fps HV ammo.
