Just fired some 25-45 Sharps loads assembled with aa2200 powder listed on Sharps web site. First loads were 24gr of aa2200 with Speer 87gr SP. accurate 1/2"groups, Vel. was only 2575fps avg. There max of 25gr. also accurate, but vel. was 2675fps avg. much slower than the 2970fps they post on their site. I went up to 25.3gr went up to 2725fps still slow. Suprise was same powder, but with 100gr. Sierra SP flat base 23.5gr of aa2200 vel. was 2565fps avg. also accurate. all loads W-W 223brass and win. #41 primers no singes of pressure rounded primer edges. All loads 2.260 COL all fed well. Going to increase to increase the load to 23.8-24.1gr for the 100gr Sierra will keep you posted. PS barrel is 20" sharps LW SS. Anyone trying a different powder with higher Vel. ?
