The Grendel Kool-aid drinkers will neglect to tell you that once you step away from the 123gr match bullets it's hunting bullet ballistics aren't so hot.
You stack the deck using a tiny (64 grain) bullet with the lousiest BC you can find- .234- to support your position?
How about changing the flavor of your "Kool-Aid" and punch in the 123 grain Hornady SST with a .510
Kinda blows a hole in your "theory", huh?
And it'll blow a hole in a Whitetail at 600 yards, too...
