My favorite and most accurate load consist of a 168gr SMK over 41.4grs of H-4895 in Lake City brass with a Federal GM 210 M primer. I seat the bullet to obtain a COAL of 2.80". This load, IN MY RIFLE,a SAI NM with a 1 in 11"twist barrel will have an average MV of about 2635fps and print a three quarter inch group at 100yds. To be safe, start with a reduced charge and work up gradually. Also, be sure to seat the primers BELOW the surface of the case.HTH
