Owerbelts are all I use I shoot 110grs of 777 and a 295gr powerbelt aerotip have killed deer from 50 yards all the way out to 140 yards all 1 shot kills most droped on the spot had one go 30 yards. Your load should work but personally I like heavier bullets lilt 270gr-300gr. I'm sighted in 2in high at 50 yards and at 125 IM right at dead on.
