Very legit reason.
60-70 grains does make a soft shooting load.
Iirc the original loading for civil war muskets was 60 gr 2f black powder and 525 gr mini ball. I could be mistaken though.
LoL you run a little light on the powder. My brother runs 120fffg with a .570 prb in his Great plains rifle.
It shoots pretty flat to 120 yards.
The load seems pretty well balanced, the snow in front of the muzzle only had a few specks of unburned powder, so it was a complete burn. No waste, but did get me thinking that the path to greater recoil tolerance could be in increasing doses of black powder rather than larger caliber rifles.
