Pressure tested 7383 with heavy powder load. 870 gr with 128 gr of 7383-- All that could be put in REM plastic and keep length to what would feed from magazine of a 3" gun, after it was roll crimped with tool in drillpress. 1513 fps-- 14700 psi. That is a slug 50% heavier than factory Buckhammer at little faster speed and at little less pressure. Ignition perfect, cases fall out. Love that $3 a lb powder.Ed
