Just curious. Looking at the locations of the posters, could it be that the size of the coyotes - western vs eastern - might be a factor with how the bullets perform and why people might be having differing results with the same bullets.
I think you have a valid point there. Ive shot a number of Texas coyotes which seemed to go about 25 pounds apiece and had no issues folding them up with a lightly loaded .222 and 50 gr. soft points.
For our Montana coyotes which average bigger I really like a .223 stoked to the gills, or better yet a .22-250 loaded to its potential...
