38 grains of H4895 behind a 125 grain bullet in my daughter’s 308 gave 2500fps with good accuracy. It kicked like a popgun and she killed a dozen or so deer with it. Initially I loaded the Sierra PH and later switched to the Nosler Accubond. I’m not sure a better whitetail load really exists. 4198 may be magic, but I don’t see how it could be any better. I’m sure there’s lots of ways to get it done.
