Found another powder that works with small
primers in plastic and RMC cases, w/600gr slug.
It is IMR 4227. Ignition perfect, same load
levels and velocities as 4759.
Powders slower than shotgun type, that ignite
properly with small primers(shotgun-lg rifle);
we found 4759, VV-110, 4227, 7383 surplus,
the latter a slow powder that also works
with real heavy slugs
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
