Depends on EXACTLY what you have, condition, accessories, box, papers, age, etc..
A Ruger Bearcat is listed as $275-$400, depending on exactly which model, condition, box, papers, etc.
50-400 depending on specifics
The Blackhawk was not made in 22 LR. If you have one with "Blackhawk" on the frame, you need to call Ruger. There is an almost astronomical chance that you could have a factory experimental, but, I doubt it. More likely you have a Single Six of some type or maybe a Bear Cat. Any of the 22 revolvers can range from 50-400 depending on specifics.
Go to gunbroker.com look what they are going for...

Rifles: Lowest caliber = .357, highest caliber = .44mag Pistols: Lowest caliber = .38, highest caliber = .454mag or a .50AE
I would suggest, the value of the weapon talked about would be what the market would bear.
A .22 caliber in pistol or long rifle would only have the velocity to preform this shot in a very exact set of circumstances. Being in close proximity to the bear and the specific angle at which the shot was taken. The only tissue soft enough is that of the orbital cavity (eye) then on upwards to the brain. Any further distance and or location you would not have the velocity or penetration power to make the shot. In my opinion it is so unlikely that all the variables would line up, my answer would ultimately have to be no. Although one in a million could defy these odds. YES.!! it can. if you hit it in the eye and you can run faster than it it will die a week later
As said below. Bears have been killed with about every firearm made, HOWEVER, the .45 ACP does not have the energy to insure a quick, clean kill- and would be likely to get the shooter killed- by the bear.
The GP100 is a great revolver, but if you're backpacking in Alaska - where you could be subject to encountering bear - you would definitely much rather have the .454 Casull.
Buffalo. Bear. Cougar. Indian uprisings.
It would cost about $40.00 . Answer two: The value of a care bear depends on what size it is, and how rare it is. Also the value is higher if the bear is in it's original box.
