Back in 79/80, coyotes were bringing up to $250/$300.00 here. I sold a nice one to the taxidermist here in town for $100.00 - un-skinned and with a huge hole in one side. .257 AckImp 87gr. @ 3,650fps. 200yards. Bullet blew up on the hide, making a huge hole, removing almost all the ribs on that side and no touching the lungs or heart. Weirdest thing I ever saw. The hole was like 7" or 8" round.
The coyote was laying on his side, still breathing. I got back into the truck and drove up and killed him with the .22LR - one in the melon. This was on a huge 1/4 section field.
