Bears were hunted with traps or dogs back in the day, and I imagine that a .36 ball fired at point-blank range just behind the ear would be adequate for the job of finishing off a trapped black bear. The bear pistol that was on display at Cade's Cove last year is .34 caliber, and Montreville Plott used a .40, IIRC. I've also run across a reference to a 20th century bear hunter with an impressive kill count that favored a .22 Hornet - the source suggested that he shot quite a number of those while they were in traps. I don't think that the small caliber rules out use to kill bears.
Having said that, is there a history of this one being used as a bear gun? .36 wasn't uncommon as a self-defense round and I'm not seeing anything that would mark this as a "bear pistol" as opposed to a nice, folksy pistol for self defense.
The three other bear pistols of which I am aware are all products of the Appalachians (two, the Matthew Gillespie pistol and the Plott pistol, come from the area around Asheville in western NC). Not sure about this one, even accounting for the fact that brass was occasionally used up here.
Now, that particular pistol, or long barrel and if decent sights, would make a great bunny gun.
Interesting 'take' on it. Yes, a bear could easily - well, maybe not easily killed by a .36 ball behind the ear, or through it, however a trapped bear would not be still in trying to get out of the trap and at the 'trapper' - or - not still due to attempting to escape. In either scenario, I fail to see an opportunity to shoot him/it fairly behind the ear. Not a worth while goal, I would think. In order to have an ear shot, there would need to be 2 people, or 1 person and a dog, etc., with one catching the attention of the bruin, they other to administer the coup'de'gras.
I would prefer something like a 12 bore pistol, thanks very much.
For trapped read "trapped or treed."
You might be right about specifically behind the ear, although a pack of hounds would be plenty of distraction, and there are other kinds of traps besides steel ones - Pen traps made from wooden logs were used up here in the Appalachians, and are described in Foxfire 5. Either of those scenarios might allow for a bullet behind the ear, as opposed to between the eyes or under the muzzle (both mentioned in Foxfire 5).
In any case, all I meant was that, in contrast to modern hunting tactics, period bear hunting methods did allow for very precisely placed shots at very close range, if not behind the ear then in other similarly critical spots. The historical use of small calibers shouldn't be in dispute - Montraville Plott killed 211 bears with a .40 pistol and Foxfire 5 has interviews describing the use of .22s on treed bears. They obviously work just fine, and I was trying to remind folks why.
Incidentally, I grew up and still live very close to the area in which both Matthew Gillespie and Montraville Plott used their bear pistols, and while I don't know the situation in the 19th century, today at least the local bears, while quite numerous, aren't very big at all. A decent sized boar runs to about 350 pounds, I believe, with the sows and young 'uns correspondingly smaller. I've never hunted them (yet!) I but the ones I've seen aren't all that intimidating and I don't think I'd worry unduly about getting close to one if the circumstances were right. If I was used to bears that ran 600-800 pounds or more, like the coastal bears here in NC, I might have a different attitude.
