Far from my first choice but if the 45acp is all ya got, then a 200-230gr+P lead solid with large flat point would be my choice.Buffalo bore +p hard cast lead. I think it would be fairly effective. As a last resort of course.
Remember that bison were hunted to near extinction by guns with rainbow trajectories.
^agreed^ though admittedly, if I were visiting Bear Country, I would borrow a .44 Mag or .454 Casull...if a .45 is the only option, make sure ya have plenty of ammo and that the gun is easily accessible at a moments notice...Far from my first choice but if the 45acp is all ya got, then a 200-230gr+P lead solid with large flat point would be my choice.
I have prop tools for just bout every job. A 3-4" 44ag is preferred forva ber country jamboree. Currently working on a 10mm load that will be up to the task; 220gr fp @ 1100fps. If one handloads the 45acp, a 255gr LFP @ 900fps is no slouch.^agreed^ though admittedly, if I were visiting Bear Country, I would borrow a .44 Mag or .454 Casull...if a .45 is the only option, make sure ya have plenty of ammo and that the gun is easily accessible at a moments notice...
Great advice, JSG!I suppose this would depend on just what kind of bears you might encounter. For black bear which seldom weight over 350lbs Fred's solution with a heavy bullet would be better than a sharp stick if deployed accurately. With bears capsicum compounds are sometimes effective and you might look into "bear spray".
With a Grizz things get serious and I doubt if a 45ACP would do the job quickly enough. He might wander off and die eventually, but you yourself would in the meantime have a brief but violent existence. Only a brain shot would be adequate for a relatively quick stop. Again, bear spray has been relatively effective on some large bears, and if approached, there is some survivor evidence to indicate that playing dead also works if you are not actually being chewed on at the time. Once an attack begins, playing dead seems to go from playing to really dead in a short period of time.
Don't stop to admire some cute cubs you may see. Retreat in the direction you came from and hope the mother is otherwise occupied. If she thinks you are a threat to her cubs excitement will ensue.
It is a myth that bears have poor eyesight. Recent evidence suggests they see about as well as we do. They are extremely alert and have a sense of smell several times greater than a bloodhound, coupled with hearing that a dog would envy. Aside from a sow with cubs, young "bachelor" male Grizzlies who are out seeking a female, are the greatest threat. They will actually stalk you and charge from cover if you enter what they consider to be their territory. They will stay in an area where they may have a carcass too, so if you trip over a dead dear or something it is time to leave.
