My vote is for the .243 Rifle also....I've shot several coyotes with my .243 and just went out this evening with it again but didn't see any coyotestoday.I mostly hunt Deer with the .243 Browning A-bolt and I have 2 nice Bucks on the wall to prove it and have shot several Does and never lost a deer yet!I'm shooting 100 grain Hornady"Custom" bullets and using a Leupold 3 X9 X 40mm scope.
