Wait. What?!?!
From the Hodgdon/IMR site:
.308, 175gr SMK
H4895 Start: 40.0gr, 2489 fps, 39,100cup \ Max: 42.7gr,2647, 49,000 cup
IMR 4895 Start: 41.0gr, 2463 fps, 42,800psi \ Max: 45.0c, 2704fps, 57,800psi
If I ever run into anything even close to that much lot-to-lot varrience I will quit loading ammunition. Period.
If I ever get handed a hand loaded cartridge by someone who says "Sorry, I don't pay attention to IMR vs H" I will most likely run. And I hate running.![]()
