12GA rifle From Hell--

[hubel458]

Along with the two slower than shotgun powders, IMR 4759
and VV N110 that ignite reliably with shotgun primers,
that are easier to load for slugs, in heavy bbl can
get 20% plus more velocity, I've found another. It is
IMR 7383 $3 a lb surplus. Tested plastic 3" cases, perfect ignition with regular primers. 8 types of cases,600gr slug
starting load 100gr. Full load 140gr giving 1800 fps plus
in 24" bbl NEF.With loads halfway between start and full
didn't even have to resize to shoot again.Full load just has
a card wad under slug in 3" plastic.Wad just tight on
charge, as no extreme compression of powder needed.
Will do heavier slugs and
RMC brass cases. Ed
