Poprivit, I sent you a PM. My Alaskan was regulated for the 300gr 45-70Federal factory load, but I handload and worked up a 350grRN Hornady load with Starline brass and 60grs. of Varget powder. It is at 2000fps with about 3000flbs of energy. The pressure is low thanks to the Varget powder. It kicks a little, but is very accurate. I did have to replace the front sight blade since it was shooting high with my handload, but blades are readily available from NEGC and Midway.
