I have shot many called coyotes and seen many more shot by my son and brothers. The vast majority of ours are shot with 223 and usually out of an AR. How ever, the 17 rem, 22 250, and 220 swift also work well. A friend that is a contrast caller uses a 243.
If I was confined to one gun for coyotes, it would be a 223 shooting 40 grain plastic tip bullets, in a bolt rifle. Most of those that call with me would say the same, only in an AR.
