I'm using a 30-06 for Orxy hynting.I've already sighted my rifle for twohundred yards, using 165 grain Noler Fail safe bullets, I.M.R 4350 powder( 53.3 grains ), and CCI primers. My manual states that this load should leave the muzzle at 2692 fps. What would I gain by loading 54.3 grains of powder.?
