A Brenneke 28ga slug is a 5/8 ounce, or by my calculation 273gr, moving at 1450fps (Brenneke's number). Hunting with that wouldn't make me weak in the knees. A friend shot a deer with his .54 round ball out of his long rifle and anchored it, and as you point out the two are comparable.
I built this .54 flintlock back in the 80s, have killed about 50 deer with it...A .530 round ball weighs about 220 grains, I use 80grs FFF Goex and have dropped deer out to 125 yards...I see no problem...
