For whitetail , in both the grendel and the creed, I'm leaning towards doing some testing with the lighter weight hammer bullets. Thinking the 110 hammer hunter at somewhere over 3000 fps in the creed and the 99gr hunter in the grendel , hopefully north of 2700 fps. Light bullets for caliber, in light calibers. Light recoil and I dont think a deer alive could stand either one in the boiler room !
