I ran some loads with Hornady 123gr SSTs and CCI 41 primers in Federal brass with A2460. I started with 25gr and went to 28.0 - velocity at 27.0 was 2377 fps with a low SD (4) on a 4-shot group, and 28.0 gr was 2456 fps with the same SD. My PSA 20" grouped best with 27gr, and I plan to go back and do some more tests. It cycled well in the AR. I had a max of 28.2gr listed from the loading data I could find.
