I’ve only used the 17rem but my results on a few coyotes with 20vmax wasn’t very good. Usually had to shoot them again if possible. Never lost any but only out of luck. Even right behind the shoulder shots and they’d run a good ways. Never shot them “on” the shoulder because I knew the bullets were blowing up. I shot 25vmax after that and they seemed to hit with a lot more authority on coyotes. Shot a few bobcats with the 25vmax. Never had one exit even on broadside shots but they were called in and inside 100 yards where the velocity was still up. I bought a box of woodchuck 25bthp to try. They shoot very well but now I’m playing with the 20 practical and haven’t shot them at game yet.
