I once shot a 237 grain .54 cal. patched round ball out of my .54 cal. Leman Trade rifle, with a 1 1/16" barrel, ahead of somewhere around 240 gr. of Goex ffg. Accidentally!! I won't go into how the accidental loading happened, but it did not involve alcohol, I promise.
I have no idea what the foot pounds of energy was on that load, but the tang sight recoiled into the bridge of my nose and laid it open like a knife. In retrospect I believe it would have killed any living thing it was aimed at. It nearly got me.
But, no harm whatsoever to the rifle.
