Now that Darryl has the ENTIRE shooting world convinced of the effective application of Matchking bullets on big game, I have a question. I am shooting a Sierra 80gr Matchking at >3,600 ft/sec from my 22-243AI. Rich M. from Sierra told me that this would not be a good bullet for shooting varmints because it has a heavy jacket and might drill through vermin like a pencil. Any idea how this bullet would react if I used it for taking whitetails????
