With 31.2gr of CFE under the 123gr A-MAX, COL = 2.275", I'm at 2500fps. 31.1gr gives me 2489, 31.4 = 2520, 31.7 = 2532, 32.0 = 2553
I mass produced the 31.2gr load last year before I explored beyond it, but 2500fps from a 16" with a .510 BC makes me pretty happy.
The 20" Lilja gave me 2602fps with factory 123gr SST. I had no issues with the primers on any of these loads-everything was nicely dimpled, although primer signs are unreliable for determining pressure. I mention that because some have reported pierced primers in other guns.
