.22mag will be quieter than the .22horn but the horn will definitely put the crackdown on a coyote. The only real problem I have found with the hornet is case life. 3 hot loads and they are done. The old man preferred the .220 swift and .22-250 but both of those are ear busters. Even his long barreled, 29 inch, .220 swift is freakishly loud. I just drilled a coyote out back last night with it. Damn ears are still ringing. Guess I should have got more of the barrel outside the door huh.
