Actually most of the old timers here know that the high point of efficiency is usually close to the high point for accuracy. Pushing a bunch of unburnt or having the powder burn in the air after it leaves the barrel adds only more recoil.With faster burning powder heavier bullets ect. you change that somewhat but for practical use with most powders the peak of efficiency is around 110 grains this includes all the subs and black powder with the exception of Blackhorn 209 which is progressive burning which is a different type. all this is in a 50 caliber as the caliber changes the point of efficiency.My opinion its free so take it for what it is worth to you. I realize there may some controversy here especially from short timers.
