Yeah 158 grain, at 1346 fps. It's a butt kicking load for sure. That's 635 ft-lbs of energy from a 4.25" gun. N110 is close to H110 in burn rate, but I never quite got this sort of velocity with H110. I went up to 16.4 grains of H110 (16.7 max according to hodgdon) and only got 1210 fps. N110 produces less flash and concussion than H110 too.
