I've beenlurking in the 12g FH posts for a few months.I amamazed at the things you are doing. Pure genius. I'm saving my pennies for a replica '87, a heavy rifled barrel and some Rocky Mountain Cases. Itshould be just the thing for Brown Bear in the thick. I have a NEF and have always suspected it had potential, just not 10,000 ft.lbs. worth!In the meantime, do you think itispossible to use SR 4759or RL-15 in 12g 3-inch plastic cases with 900 grain ((.600 NE solid)sabots) and keep pressures in the12-15K range for use in modern pump guns?4000 Ft. Lbs would be nice. Just an idea I can't get out of my head. If not, I'll try to beg some 600g Dixie Slugs from Mr. Gates, or settle for 600 grain .505 sabots and start having some fun.

With bullets that heavy you'd have too high of pressures with 4759
for plastic cases. Possibly could do it with RL-15 and starter
powder in plastic, but only in heavy barreled like NEF.
But the 600 gr Dixie is still the best for
most uses in plastic. A NEF and brass cases would handle 900 gr
Saboted bullet with RL-15 and starter powder. Start
at 80 gr Rl-15 and go up if cases don't expand to much to resize.Ed

Thanks Ed. I thought so.

Here is pic of a double that I will put
barrels in, monoblock style, using the breech
section for the monoblock. This one will be
for 28GA FH. May get another same size for
my 510HE. I will be able to run full pressures
with these.....I am trying to find a bigger,
heavier one to put 12GA FH in. I want
heavier one so as to run pressures like my
Savage as a minimum.Ed.

that crazy

I was looking at an 8ga single on
GB, that looked heavy enough to put
a barrel in for 12ga or 700HE. They
wanted much more than it cost
new.It was a real heavy
Spanish single. If I found an extra,
or the 8ga Tonolini double, I might
leave it 8ga, as I could make a few
cases by reworking 20mm Suzy brass,
can be done without adding rim,which would
be super strong cases like our 12ga FH.Ed

Had question about locking RMC cases onto
lead slugs, as they don't crimp into the
grooves well as sharp bend works thick
mouth. First I resize tight and slightly bell
mouth.Insert slugs which take a little pressure.
Then I use a die with slightly more
taper and swage the mouth into slug, like
the fit you get with bottleneck cases.
Same deal works with our long cases made
from BMG brass.Ed[/align]

Preliminary testing with VV N-110 powder shows
it works with small primers like the 4759 powder does,
in plastic cases. Perfect ignition on first
bunch of loads with 600gr slugs.Ed

More VV N-110 testing that we got done.
Starting loads are 60 gr min like 4759 for good
ignition,600gr slug. In 2 & 3/4" plastic full load is 75gr
with card and 1/4" cushion wad.In Nef 24" bbl 1700fps.
In 3" plastic 87gr, card and 3/8" wad, 1800 plus.
In RMC brass case. 100gr, card and 1/2 wad 1900 plus.
All running same safe pressures as 4759 lab tested.
So that is two powders that are slower than shotgun
powders, and much safer to work with for regular
primers, giving at least 20% more velocity. Ed

Testing soft buckhammer vs hard Dixie. Dixie 600 gr,
Buckhammer from factory hull 640gr with locked on wad,both
out of Savage at 2300. Dixie went through 2 -1/8" steel
sheets and on through two more 3 feet away.Buckhammer
went through first two with same round hole, but made
a bunch of dents and one cockeyed hole 3 ft away.Ed
