Greetings @
Tim Dicko,
I am rather loath to admit that the rifle has fired barely 50 rounds. The factory 150 grain Corekokt loads chronographed 3,080 fps and handloads with the same projectile and 68 grains of AR2217 (Hodgdons ADI max) produced 2,985 fps. This was with Winchester WLR primers. I have since switched to Federal 215GM primers but have not chronographed that load. Initially I tried AR2213SC powder but couldn't reach 2,900 fps at book max. I have read that AR2209 works well in the SAUM but have not tried it yet.I tried the Hornady Amax projectile briefly but at 74mm oa it is a single load only and shot left of the 150 grain. Much more needs to be done which I must get on to.
Regards Grandpamac.
