I'm not a Trapper, but this was the first coyote I (managed to) save the pelt.
I made a mess of this guy, two entry holes / one 8" exit across the neck&shoulder area and one 1" exit hole / and blew 1 of his back legs off. I even managed to catch the last 3" of his tail, shot it off too !
I sewed his neck up, but initially missed the 2nd exit hole on the opposite side. It's about an inch wide hole.
