Just picked up a new kimber stainless target, and got it out today with my reloads. 155gr lasercast round nose, over 7gr of unique and 170swc lasercast over 7.9 of aa5. Both were very accurate at 25yds. No issues with the gun or mags. A little fine tuning of the sight was all. The 170's were pitching brass pretty far behind me. Is a change of recoil spring in order? Just have the stock 18.5 in it now. Just under 250 rounds total. Really impressed and will load up some more throughout the week.
