I plugged some with my one M3 shooting 32gr slugs around 1,040fps. But because of how I hunt them, I switched to a .30 in a completely different gun. Noticeable difference. I prefer every coyote that enters my scope is a dead coyote. The .25 would kill them with a boiler room shot but I lived in fear of the shoulder blade. Now a 60+ grain .30 just delivers more smashing power.
