Home Forums Hunting & Shooting Ask The Gunwriters New IMR powders for sale from Hodgdon

Hodgdon has their online "Reloading Data Center" updated with the new powders. Performance with IMR 4451 and 180s in the 30-06 appears to be similar to H4350 and IMR4350, for velocity. They say 55.5 grains should give about 2750 fps out of a 24-inch barrel, at under 60K PSI (SAAMI standard). Not that I would load above a manufacturer's recommendation for the old war horse...
