Fish, along your line of thought, the corelock and Hornady Interlock are similar type bullets, and Weatherby loads them in their factory ammo as their lower cost offering. I suspect if I popped a dear with my 240 wby mag loaded with the 87 grain or 100 grain, blacktail, or muley, that deer is in trouble. Sure I now load the premiums, but there never has been anything wrong with the corelok, or interlok in my mind for deer sized game, for sure.
