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

Tested 7383 with 730gr Dixie, 130gr gets 1650 plus fps
in NEF 24" bbl. Used 3" plastic cases. Same low expansion
as 7383 the 600gr loads and the 4759 lab tested loads.
Ignition perfect, no hesitation.Ed

Tested 800g slug with 7383 in plastic.Works good.
Have question about different cases and dies.
The RMC cases use a shotgun primer, thus they have
a real thick base. They are not a thin headed,
balloon headed case, and RMC makes sides thick
enough for regular 12ga wads.
But in a break action the 3" plastic cases
with our 4759, VV110, 7383 loads are close to RMC in
power. Can buy a hundred plastic for price of one RMC.
3.5" chamber 12ga with plastic is as good as RMC for 3"
And if I shot RMC in Savage to get more power,
which I could do as far as the firing process,
the expansion above the base, due to being a turned case
would make extraction stiff, causing extractor to
damage rim. A turned rim will not take what[/align]a drawn one will. Rcbs set should do RMC easy.Ed[/align]

Finished test of 7383/870 slug in NEF.
Tested 870gr hardened slug with 118gr of
7383, got 1500 plus. Perfect ignition.
Cases ejected easy, and has same base
expansion as the 600 gr slug/140gr 7383.
Will have these pressure/velocity tested
in few weeks.Ed

Tested a 750 gr banded solid, grooves .009 smaller
than land diameter and got same velocity as
with lead slug weighing the same at same pressure.
Other banded brass slugs with groove debth
same as land raised pressures compared to lead.
Got 2700 easy with 750gr, in long case in Savage.Ed

I guess this has become your personal diary, used to be a hot topic, maybe when you get rich and famous, you can publish this.

Is there a lottory I could enter to win one of these things?

The folks at 50 Cal suggested we write up a
piece on the 12GA FH. Interested in what we
did to make hairy cartridge using 50 cal brass
adapted to the 12 gauge shotgun platform.
A job for Rob to do? His wild idea has been
viewed about 400,000 times in the forums
we put it in.Ed

Anyone got any long 12ga rifled 30" plus
barrels, 1.3" plus diameter. Barrel
guy is shutting down and returning funds.
Been waiting for 12ga heavy barrel for
87 levergun since last summer.Boy it is
hard getting projects done.Ed

So what are your selection criteria for a shotgun platform ? I've been toying with the 460 S&W paired with a .410 for some time but have not located any sources for a suitability guide . I've seen 1 book offered but its a 60 dollar book andwould take weeks to sift through . I would like to do an O/U .
