The faster they move, of course, the more damage they do, but a round ball loases velocity fast! Yet, within 100 yards, a .54 will make a pretty big hole all the way through a deer, and at least 3/4 of the way through an elk. And naturally, the .58 is even bettedr.

My .58 with a 1/60" twist is accurate at 100 yards with a 570-grain Minie ball as well as a PRB!

The Lyman 570-grain 57730 Minie bullet between two .45/70 rounds. Do you think that bullet will kill elk (or whatever) at 1200 FPS MV??
