Thread: Subsonic project

Pistol powders are typically Shotgun powders, your ADI AP70N, AP100N etc. 44mag is a pistol calibre. Lots of load data for those powders from manufacturers. Also , for supersonic, there is H110 aka W296 aka Belmont Action Pistol. A Goto powder for 44 Magnum and .410 Bore Shotgun. Observe the published load data. Downloading this fine ballpowder is likely to punish you in the most horrible of ways. So not a candidate I suspect for your sub loads.
