I've been reading advice about hunting deer with the old PRB - putting the max range at about 75 yards or so. For whatever reason, my woodsman .50 likes round ball at a small 50 grain powder charge -- which is pretty light for mulies & blacktails (150 - 200 lb). So I've been thinking about going with a conical. However, some of these new big bore air guns on the market are being used at muzzleloader distances (<100 yards) for big game hunting. These only run about 600 fpe at the muzzle and in 45-50 caliber. So we're talking VERY weak muzzleloader ballistics. There isn't the same wide range of use, obviously, but claims of full pass-through on elk, deer & hogs are being reported. There are some key differences, not the least of which are the use of scopes and better triggers that allow shooters to be much more precise with these air guns. However, if rifle of 45 caliber with 600 fpe max at the muzzle is enough to take down an elk, why would a 50 caliber round ball be too weak at 100 yards with 300-400 fpe remaining? Please note, I'm a newbie so I'm just trying to wrap my head around this. I'll also put my cards on the table and say that I'm planning my first muzzleloader hunt this fall and would like to use PRB. I have a few reasons why but I just prefer it. I can still hunt with a conical without giving up a thing in accuracy. I just like PRBs better. All thoughts are appreciated.
