4KED Horn,I can see from your post that you have no confidence in a handgun to stop Bears I lived in Alaska for 7 years in the 80's and know of at least one Deer hunter that was killed by a bear. Also I shot a Grizzly Bear and a 53 inch Moose With a 475 revolver and am convinced that the performance is more than adiquate.The bear came in while I was removeing the horns from a moose.Also these revolvers from 45 caliber up work extremely well notice I am not an advocate of the 44 I have used them and seen others use them and contrary to what I have heard some say about their effectivness I donot believe that a 44 is in the same leage as 45, and up ie; heavy loaded 45colt[325grain 1300 plus fps 454 360grain,475 420grain ,500JRH,500Linebaugh with 500to525grain Bullets]
I have tried the 435 grain class bullets in the 500Linebaugh and didnot find them to penetrate and enough and found their effectiveness lacking,also a flat point bullet such as a LBT LFN is the preffered bullet style. If you would care to look at www.BuffaloBore.com.
under field photo,s and story,s their is a photo of A Bison I killed with one shot. bullet exited.Performance was quite impressive.If you don,t believe me about the effectivness of these big bore revolvers ask Fiftydriver as he shoots some big bore revolvers also. I can asure you that you DONOT need to remove the front sight and sooth the barrel.
range it,check the wind, dial in correction, aim and only one shot
