I have also seen bear shot with the ruger 44 mag semi rifle .. And the bear died just as fast as a deer would have .. As long as the bear is in the 200 -250 range you can do OK with a 44 ..As I have said before I hunt over dogs ,, some times the bear trees and a 44 will kill any bear out there`; and sometimes you have a bay up on the ground ,, The bigger the bear the more apt you are to have a bay up and you will be very close too the bear when you shoot it as the bear will bay up in the worst sh&t hole it can find ..I have seen four inches of fat on a large boar in the fall and the bear weighed 500 plus ... A 44 is just not enough gun in this case .. First the gun has too stop the bear ; from hurting dogs ; and in most cases you are very close and your safety in jeopardy also . So I simply do not use a 44 in case I end up on a bigger bear .. I love Ruger 44 mag guns .. They are semi and short .. The gun of choice is a 12 gauge loaded with 1 ounce slugs .. not the sabot ones . they are 50 caliber and the one ounce one are the full 72 caliber
