Yes I know those coyotes are real *******s I have shot 5 over a dead cow (they did not kill it it just died) and you can not tell me they do not have a taste for domestic animals. Anyway at 50 yards a 22lr semi auto works but not the long range shots even if you hit them. They are tough bad shot placement even with a high power don't work so well. I shot at one off hand at about 150yards and I do not know what happend ether he steped forward when i pulled the trigger or my aim was off(243 wincester). anyway i hit him in the spine just in front of the back legs well he took off on his front wile leaving a gigantic blood trail. eventualy I caught up to him thinking he was dead, Nope he tryed to bite me so I shot him again. But they do take calfs before they even drop. you lost more than $500 that day think of the expence for feeding the cows and what they would of brought come fall if you were goin to sell them. Even more if you were going to keep them for breeding. With calfs they tend to not even kill them they just start eating. You should of fired warning shots then you may not of lost the calfs.
