I will throw the 155.5 Berger full bore into the mix as well if you cannot get the scenar. I start at 45gr of varget and start adding powder till I get 2900fps, accuracy is usually there all along. Took 47.3gr in a 22" barrel and 46.5gr in a 26" tube.
I tried the 155 amax and had an occassional flier I could not account for, maybe one in 20 shots would be significantly outside my clearly defined wobble pattern.
Recommending the 155.5 just for external ballistics, have yet to smack anything with it and I dont recall if it is recommended by Berger.
