What's wrong with the 270 for killing coyotes? Do people think it's too "cruel"? Don't they realize that "Dead" is dead with the animal not suffering.
I never knew there were "rules" about using too large a caliber. Remember once when I was a kid and my Dad shot a dog that was running out sheep. Had one down and my Dad put one right through the rib cage with a 180 gr 30-06 round @120 yards or so. Dog did a double back flip and didn't move from where it landed. When I went down to dispose of it, I found a dog that weighed about 75 lbs and had a hole the size of a grapefruit as an exit. I considered the '06 to be just right
