A friend and I shot 2 pups with this bullet two weekends ago. The first one was hit in the guts at about 200 yards and it completely disemboweled him. You could have put a football into the exit wound. It was simply killer and terribly destructive performance.
The second pup was shot around 150 yards in the neck and it dropped him right where he stood. There was no visible exit wound in the offside hide but when we cut his ears off there was massive amounts of internal damage all the way into his brain.
I'm not sure why the shot in the guts split him wide open and the shot through the neck produced no visible exit wound but that's my limited experience with the bullet.
I have used them very effectively out of an ar for coyotes. I have never shot smaller dogs but on the adults the damage to pelts has been very minimal. Very good at putting the coyote down right where you hit them.
I have shot all kinds of game with the smk 69 out of a 223 bolt gun. from yote's, deer, hogs, bobcats, even a cow one time. i never had any trouble out of them. i jut have not shot any out my AR 15 i don't like reloading that much!!!!!!!!!!!!!!!
