I am currently using 63 grains retumbo with 140 grain accubonds with a winchester mod 70 26" barrel groups are half inch or less if i do my part at 100 yards. pro chrony says average vel is 3062, but drop test at 500 and 750 put trajectory validation at 3238 ft per sec. this is 1/2 grain below max on hodgens load data but in my rifle it is MAX load.
