same WC: 1133fps

The 800x loads were like heavy .40 loads, nice shooting. 8.2 800x shot the best group at 25yds 1.3" bench rest. All velocities are an avg. of 5 shots over my chrono. The temp was 30f and elevation was 5800ft. OAL was 1.26".
I have info on other loads that I tried if anyone is interested.

WC= West Coast 220, PB= Precision Bullet.

All loads use CCI 350 primers and 1.26" OAL
