Actual data over my Shooting Chrony with my guns at about 10' from the muzzle. Use this loading data at your own risk.
15.0 gr H110 under Xtreme 158gr PHP yielded 1235 fps and high max spread in a 4" Taurus M66 and 1720 fps and high max spread in a Rossi M92 with 20". I think I should have had a little higher load to reduce max spread. I lost interest in working with that bullet in magnum loads because so many better 158 gr HP bullets are available so I didn't do more load development.
13.1 gr H110 under an MBC 180 gr coated WFN lead bullet yielded 1140 fps and a tight max spread in the Taurus and 1570 fps in the Rossi again with good spread. Incidentally, these numbers were almost identical to the HSM 180 gr GCWFN factory load, which is what I was hoping for. That stays loaded in the Taurus because we have plenty of bears for neighbors.
