I think shooting a buff with a 45/70 is pure stunt since the hunt, stalk and shot are all pretty similar to what would happen if the hunter were using a real, legal, DG rifle. Some shot angles might be precluded with a 45/70, but then some are precluded with a 375, some shots possible with , say, Saeeds 404/375, are not possible with a 458wm...

In the end the only difference is the rifle, and the stunt hunter is trumpetting his rifle and cartridge. When the shooter says, "Wow, look at the extraordinary performance of this bullet and load out of this rifle, see, it can be done", you have a stunt hunt, when the shooter says, "Performance was, as expected, just fine", you just have a good hunt.

Switch rifles the minimum, a 9.3x62, or 375H&H, and the hunt would go the same except it would be legal and the hunter would stand a better chance of stopping a charge.

Bow hunting is different. The stalk can't end at 50yds, in tick stuff where your'r sneaking your barrel between branches...The bow hunter needs to get close every time and must end up in a position which allows him to draw the bow, and clear enough to allow for the arrows trajectory.

For this reason, the focus might be on the weapon, but really ought to be on the stalk. I think a fellow who has hunted buff with a rifle, and who goes back with a bow, is not stunt hunting since he knows what he's getting into.

For the fellow who has killed whitetails and maybe an elk or two to go buff hunting with a bow is stunt hunting.
