When shooting a wild animal there’s always an unknown factor. I’ve seen bears run off after being shot several times with .30 caliber rifles. A friend had a black bear in a tree next to his cabin. He shot it in the backside with birdshot. Three minutes later it fell down dead. You can never know what it will take to kill an animal. That’s why, in my opinion, it’s best to have more power then you would think. Too bad about all the restrictions now and coming.
