RE: SMOKELESS POWDER COMPARED TO BLACK POWDER?
If you look up what the type of velocities guys are getting out of 150gr loaded muzzleloaders you'll see that its nowhere near a .458WM. (There are alot of online calculators to find ft/lbs for a given weight projectile @ given a speed) I've heard of guys BOWHUNTING cape buffalo!!!! and this topic kinda goes back to the idea that even though you can deer hunt with a .22lr...all the rules change and its different game. We'll leave the wisdom of such actions alone because that dead horse as been beaten and re-beaten a thousand times.
