RG made, weighing 385 gr. Full .730" diameter, hollowpoint,
and one I filled nose with glue gun. Fairly streamlined. 3600 in
the Savage with our long case..Slug is nice and long,
1.22" HP and 1.4" with plastic I put in the nose.
In Nef with RMC 3.5" brass case 2700, 3.5" plastic 2500. Ed
shotgun primers,with Blue Dot starter and HBMG main load. And
I just tested some variety of ones myself.
Doing some testing with starter powder, 15gr Blue Dot, with
slower powders that fill the cases with minimum wads.
tested in 3.5" RMC case in NEF with shotgun primer,
with 36" added to barrel.Remember I have extra foot of bbl.
These 4 top loads expanded case, where I check it, just above
thick base section to .811" from .807" resized.
1000gr jacketed, 230gr HBMG, 1800 fps, 7200 ft lbs,
with 1/8" card and 1/4" felt wad.
715gr jkt, 270gr HBMG, 2200, 7600 ft lbs, 1/8" card.
600gr Dixie, 250 gr Retumbo, 2400, 7600 ft lbs, 1/8" card.
385gr jkt AL core, 250 gr RL25,2900, 7200 ft lbs.
This is faster than lighter loads in NEF, using 4227 powder.
Now the starter powder loads, which a few guys like, increase
powder speeds so that HBMG acts like RL25. In first example,
with 1000 gr in RMC case you couldn't use 230gr of RL25
as that would expand RMC brass too much and stick the case.
A few guys have found that slow powder, with starter
powder is easiest for 1000gr and heavier loads.
On another note, I've heard around the grapevine that if
enough of us ask for NEF to make available a 12ga Ultra with
a 28" rifled bull barrel that they would do it.Start calling
folks, maybe do some good. Just tell them these new sabot
and fullbore slug loads need more barrel to get the velocity
out of them. 1-866-776-9292. Ed
Lyman cast slug. It is the slug you cast to use
originally in 20ga shot cups, for slug hunting.
It is nose heavy and will work in smooth bores.
Brass 3.25" cases from Rocky Mtn Cartridge. It
will work in NEF/H&R 28ga modern break action guns
that cost 150 bucks, 26" barrel, you lengthen chamber
for the brass case. Good hunting loads would
be 2000 fps and the gun with a little weight added
and good pad would handle it fine. Had a few guys ask
about 28ga slug shooting, here is away..Ed
good defense load. Two Brenekkes doubled up in RMC
case in the NEF. 85 gr of 4227 pushing 2 one
ounce KO slugs about 1600. Bottom slug has seal.
Also found a way to adapt extra slugs to 10ga. A
515 gr Lyman slug for use in 12ga wadcup, in my
10ga, using thickwall 10ga BPI steel no slit wadcup
shortened and Lyman bottomed out in it, so it
is like a discard on impact sabot slug. Like Lightfield
and Hastings. I shaved the bottom diameter of Lyman
so it would fit tight. Similar deal for 16ga using BPI 16ga
no slit heavy shot cup and 20ga Lyman. Now we have it
so that 2 Lymans can fit 10,12,16,20,28 ga....Ed
PS- I ask all of you for a favor. Would you please go
to the thehighroad.us forums, join in and support them.
The owner has had original Highroad domain stolen from
him and he is in court to get it back. He is in
the right and if you folks show up there it will help.
And if you can stand it until court rules stay away from
the first highroad and ask your friends to do the same.
Doug
together to show how heavy of powder seal
and heavy cushion base that is needed. That
eliminates the blowouts and damage that was
happening to sabots unless I put a card
under sabot. Just used a Brenekke seal/cushion
base, epoxied to bottom of sabot. Even fired one
and it got out the barrel and 437gr slug hit
target straight. Ed
I have are set up to fire the regular 8ga
size cases, and also REM kiln cases with bases
turned smaller, where the extra short basecup
is formed over the inside cup.Just reduce to the
diameter that it chambers ok and regular case
doesn't expand very much fired in same chamber.
This idea came from UK 8ga hunters that found
it was easier to get kiln cases. Now the other
case in 8ga available is the WIN kiln case and
ones I've seen are only single thickness basecup,
but they have the step formed in them to match
the kiln case belt size. Now you can't turn them
down any to fit my chamber, BUT you can swage
them down .012" in a die with a lttle lube on the
basecup. Examining them they do expand much more
than the doubled up REMs.I fired REMs 4-5 times
with bases expanding .002", the WIN I did
expanded .005" in one shot. I will use
heavier built REMs as they are 70cents
primed and good for 4-5 shots,
no resizing, with hairy 8,000 ft lb loads.Ed
is in the water and snow) And the three with 437gr .512"
slugs I did one 2" group with peep sights and bad eyes.
Running about 2400 fps from RMC case in the NEF 12GA FH
Shot 3 of my 28ga FH with Lyman 360gr at 2100, from
the Enfield 28GA FH, and got same size group.Real windy
when testing . Going cold and ready to snow again.
Shot a 600 grain Dixie hardened heatreated slug, in Savage
in our long case at 2900 though two-- 1/4" steel plates with
2" of wood between them. Made big hole.Ed
It will be a good economical nice gun......
But not to fire factory kiln loads. They use
fast shotgun powder and peak pressures are to
quick and too high. You got to reload with our
slower powder loads. Cases are good for 4 reloads
with our loads, and inexpensive.
Before it got cold again got little more testing done.
I shot 8ga Lyman 900gr wasp-style slug out of
the Enfield at 2350. I made it from heat treated
lead REM kiln gun slugs, and it went through 6 foot
of hardwood slabs in my backstop. Hit target square,
behind chrono, which is great from smoothbore.
It is hollowbase and seems very stable.And real hard.
I shot 3 shot group, with 12ga 525gr Lyman, in 87
smoothbore long barrel levergun, At 25 yards they
all made hole like cloverleaf. Used 3.5" RMC brass, with
Lyman in a WW12-114 shotcup, going 2100.Now my
87 smooth barrel is .722" at muzzle, .726" at breech,
so it gives tight support to shotcup and Lyman slug,
for fairly accurate load.....Ed
a Vias brake installed. He had smith ream out a
50cal one to let 12ga slugs pass through...Ed
RIP with recoil as he wants to shoot all heavy slugs
in the NEF Ultra. Guys like the Vias brakes.They
can be bored out and fitted to anything.
I just like ported internal brakes and more gun weight.
Here are some results( had 1 nice day) with 8 gauge and
10ga light slug loads of my testing. I call them my real
big bore varmint loads. A 770 gr slug in 8ga fired in
Enfield at 2400 all 3 shots nearly touching at 20 yds.
A 515 gr Lyman, NEF 10ga at 2400, same tight group
at 20yds. Lyman is originally for 12ga, but is fit in
10ga thickwall BPI shotcup cut off and slug glued in so
it is like a impact discarding sabot. Both smoothbores.
Smaller varmint load. NEF rifled 12ga with RG's 385gr
aluminum cored jacketed HP slug at 2700, 2 overlapping
and one half inch away using RMC 3.5" case. Ed
light recoiling, easy to shoot. I call
them my big bore, varmint slugs as they are
light for the bore size. Here is picture of
the 3 slugs for comparison. 1st is 770gr in 8ga wadcup,
second is 515 Lyman in 10ga wadcup, third is the
12ga 385gr HP with aluminum core. The 8ga wadcup
loses its petals going out the barrel, but
hollowbase 770gr slug stays straight.The 515gr Lyman
in the 10ga thickwall wadcup is also as a unit
nose heavy and runs straight. Ed
at 29-3000 plus does to two mild steel plates with
2" wood between them. Fired from our long case
in the Savage.Two plates are soft mild steel.
In hole nice and round. Out, in back plate jagged.
Anyone interested in the 12ga Encore
with 3.5" chambers, that I tested loads in,
it is on Gunbroker..Ed
that was a 10ga.. I bored it out to 8ga and chambered
it for the heavy duty 8ga case. 770gr at 2200 out of
29" barrel. End of barrel has internal brake with 24
porting holes and with weighted thumbhole stock,
it handles recoil easy.Will have picture soon.Ed
stock, I put on in place of first one that cracked.
First one didn't break as such, just got crack
on the side where there was couple knots.
Along with weight and heavy barrel, handles recoil
great. It is a Boyd and came inleted for Savage
112, and I re-did inleting to fit 210 and
heavy barrel,and got rid of monte carlo
outline, and added full height thick pad.Ed
Both are the 12ga Ultra Slug Guns.
One has Vias brake, other expansion chamber.
He calls it his golf ball launcher. Ed
like RL15-19, IMR 4064,4198, etc. With regular shotgun
primers I had to use Blue Dot starter.
But not with these.....They are the industrial
shotgun primers used in the 8ga kiln gun cases. I use
these cases with basecup reduced in my 8 gauges.
When I set up first 8ga I fired the primers only to test
firing function(cases came with primer), then I put
regular 209 primers in to test loads, with 4759 powder.
Found box of WIN paper case kiln 3oz loads and took one
apart and noticed it had 94gr of some ball powder.
I wondered what powder is and how a regular shotgun primer
could ignite that, based on our need for starter powder
using regular rifle powders. So I fired that industrial
primer and flame and sparks came out of 8ga NEF barrel
2-3 feet. Put a regular primer in same case and flame
just a few inches. So I took REM kiln case with original
REM industrial primer and 2-3 feet of flame,and put regular
primer in and just few inches of flame. If anyone got
info on th powder used and how to get these primers,
let us know. I took some out of 8ga and put in 12ga plastic.
Using these hairy industrial primers today fired 180gr
of RL-15, in 12GA FH NEF, in 3.5" plastic cases with
437gr Brenekke KO slug. Got perfect ignition, no starter.
140gr with 600gr dixie, perfect ignition.
Also I have the 12ga Encore that we tested loads
in, on Gunbroker, in shotgun singleshot section.Ed
available it would be great. 7383 ignites fine with regular
shotgun primers in 12ga, but it is surplus and only a few of
us have it.It is a powder that has a lot of the deterrent inside
the of the material, not all near the outside like 99% of
all other powders whether spherical, tubular, or flake.
This allows easier ignition, but yet the deterrent still can
control the speed. Well the new RE-17 just out for 2 days
is setup like that. The surface of the RE-17 grains is
more porous than RE15, so that fact allows better ignition
even though a slower powder, and along with fact that company
got most deterent inside it still regulates speed.
Today I fired with regular REM and WIN primers in
plastic and RMC cases, a whole bunch of loads of RE-17,
with no hesitation or squibs or misfires. Loads ranged from
437 gr slugs to 750gr slugs today. All loads burnt clean
and I got in RMC case one of RG's 715gr jkt slugs to 2300
with 160 gr of RE-17. Using plastic you must have a strong
roll crimp with slug and wads tight.....Whoopee....Ed
and 1040 gr slug in 12GA FH NEF, and it does great.
tested loads that were cooled outside a while.Perfect ignition.
I fired loads RE-17 8ga plastic,in my 8GA FH on new NEF long
heavy barrel that was a 10 ga and RE-17 is great. No hesitation,
it fires off as good in 8ga as the 4759. Remember
I couldn't get good ignition in 8g with 4227, but so far
RE-17 is magic. In 8 ga all it would hold under the 8ga REM
wadcup with 770 gr slug is 200 gr of RE-!7, with the
wadcup pressed down, compressed real hard,good crimp,
and it really bellers.2400 plus.Going by case
expansion about 20k pressure. Which don't bother
those one piece compression molded super strong
8ga REM cases. You must have real tight proper
roll crimp in plastic cases and good tight
taper crimp or rolled in crimp in groove
in the brass cases. In RMC brass I size it so slugs
have to be shoved in with press.
And this RE-17 doesn't break up the kernels when powder
gets to a certain point, like the 7383 does, causing burning
rate to speed up more than what it was designed for.
I tested 7383 in my 700HE, and when up to 35-40k it's
pressure went up fast, much more than linear progression.
I still like 7383 at shotgun pressures, but I really like
RE-17.Just pour case full and shoot with lighter slugs.
Ok- for those who want to get into the 12GA FH and get
the long strong 3.85 inch cases Rob on AR got some made,
you can email him to get some- garnickrob@aol.com
He can also tell you where to get reamer.Ed.
of NEF 12GA FH, factory thumbhole stock
and a brake he built, with wide slots in top and round
ports on the sides. He is testing heavy slugs.Ed
They are flat on one end and hollowpoint on other.
They can be shot either direction. Aluminum ones
are 346gr, brass 1080gr........If you need any
contact him. He, RIP, and others on AR are testing
them with different powders. I have gotten similiar brass
ones to 1900 in NEF with RMC case, with
140 gr the new RL-17. Ed
RIP'S components in first picture-
15gr Blue Dot starter, thin plastic separator,
230gr HBMG, thin plastic under slug,
and 1087gr brass slug; in a RMC 3.5"
brass case, fired in his great looking,
braked NEF 12ga FH Ultra, got him
1812 fps average. Barrel and brake
are 27" total length. Great work. Ed
500gr Hornady .500 slug up to the good speed listed
on BPI"s loading sheet, using shotgun powders. I could
get them there with my loads using much larger amounts
of rifle powders. He tested 3.5" Federal plastic cases in
his Savage 210 with 3.5" chamber and the 28" heavy barrel
he put on. With 50gr of Longshot(max load for all modern
guns) he got 2550 fps, with 500gr in sabot. He use two
BPGS gas seals fitted together over the powder, then
a FS12 Flexseal wad, then a 1/4" cork wad, then the sabot.
Then a good strong roll crimp with drill/drillpress crimper.
This load is at mag shotgun pressures by case expansion
measurements and BPI's 46gr load tested at 12,500 psi.
He also did one with one BPGS and two Flexseals and had
200 fps less.He had tried other combinations seals/wads
and with same amount of powder and got lower yet.
He also went up with the powder, with seal/wads that worked
the best and got about 3000 fps, but the plastic cases
stuck and wouldn't eject easy. I will be testing same
seal and wad column in a few days, in my NEF with long
barrel to compare results.I thank Bret, he is a real
good experimenter and idea man. Everybody is trying
like crazy to get that 500gr saboted slug up to big
game gun velocities with shotgun powder and thanks to
BPI"s supply of the right components it has happened.Ed
10 gauge frame. It has the Greener crossbolt. He cut off
barrels to make a 4" long monoblock double to screw a
pair of heavy 12ga rifled Pacnor barrels into. He reamed out
monoblock section and threaded it. His barrels are
1.116" at the breach, .97" at muzzle and 22" total length.
Barrels threaded into monoblock with a 15/16" x 32 thread.
In the pics it is partly done and he will put in the ribs
and integral sight rib and regulate for accuracy.
It will be about 14.5 lbs when done he says.Ed
First of all both Bret and I have heavy tight fit barrels
and his barrel on the Savage is faster twist so it took
him 50 gr of Longshot to get what BPI got with
looser barrels and slow twist at 46 gr of Longshot.
For non heavy barreled guns only go to 46 gr.
I did a bunch of tests in my NEF long barrel with long
chamber. My store didn't have any 500gr .500" XTP slugs
so I used some 420gr .512" dia lead Great plains in the
BPI sabot. Using 2 BPGS powder seals, a BPI Flexseal, a
cork wad in 3.5" new Federal cases, roll crimped, I got
2800 fps with 420gr slug. I tried 4 other powder seals,
2 cards, a Remington, a Win, and a odd one, all with the
Flexseal and lost velocity. I fixed up my crimper so it would
roll the plastic down and over inside edge of sabot, as before
it would turn plastiC in too sharp and get some of the crimp
outside the sabot top. If sabot was too low so that the plastic
crimp went clear down to the slug I got high pressure signs.
I also did same loads in used 3.5" REM cases ok.
Now, I thought I should have more velocity, so I swaged the
.512" 420GR slug down to .500" like they say the sabot is for,
AND I GOT OVER A 120 FPS MORE. Everytime. I also used
Alliant Steel powder and got all the same results, using
60gr. It is easier on cases. I also substituted the doubled up
BPGS powder seals and the Flexseal with 520gr Lyman in
place of the seal and cushion on the WW12 wadcup the Lyman
fits in, with some RL-17 loads, of 150gr, and got over 200fps more
that the original WW12 wadcup gave with the Lyman.
Velocity secret is to have the perfect sealing setup with
slug/sabot combo that is NOT too tight. Only tight enough
to get accuracy. The cork seems to protect the sabot
base ok on the shotgun powder loads, and not needed
on the RL-17 loads, which is a easier accelerating powder
and without cork helps make room for the RE-17. I think I
will get increases in the brass RMC cases, with RE-17, with
the BPGS doubled and a Flexseal in place of cards and wads.
We will know soon.Ed
case in it, to show that the gun is strong enough
for 8ga. I was a 10ga NEF. Has 29" effective barrel
length, and the internal expansion step at muzzle
for the ports that stops muzzle climb and reduces
recoil. Which along with thick pad and thumbhole
stock makes for easy shooting.Ed
made back in the 80s. Case is for the CAWS weapon system.
Case is belted, and it and the gun operated at 25,000 psi.
Its bore size is between 12 and 10 ga size, but the od of
the drawn case would let it start in 12ga chambers, so
they added belt so it couldn't go all the way in
to regular shotguns. Notice the thick sides and corner
near the base.Heavy enough for 25,000 psi. They loaded
it with big buckshot and test other projectiles also.
They had a plastic card over shot and filler and rolled
over brass mouth for crimp. Ed
monoblock style for a .585" cal barrel, to make a NEF 585HE.
It goes on a SB2 10-12ga alloy, super strong frame. Its
OD is 1.210" and the barrel that screws into it will be tapered
to match contour and it will be 1.00" at muzzle, at 32" long.
I know these are strong enough as my 8GA FH testing shows..
Later will do couple more with heavy barrels for 28GA FH, etc,
as all the break action 28 gauges I've looked at have too
thin of muzzles for our slower, powder loads.I'll have 3 of these
that fit one SB2 frame I have here.This makes switch barrels
big power fun.Ed.
barrel and the gun is weighted to 15 lbs. Thick pad.
I have cone breech as this case is belted with thick base.
I'll have a pic of gun later. Gun is still tight after testing.
I can take out cases with my fingers as they don't stick.
First 650gr, with no extractor. The HBMG, WC-860,AA8700,
Retumbo, Magpro, RE25, W-780 loads come out of the chamber,
with my fingers.If I tip gun up they fall out.
Top speed with RE25 and W-780 is over 2400. Now I knew what
to load them at because I have tested this case in 3 other guns.
I have all the different powders and bullets tested.
This is example of a case extracting easy,
due to proper side taper that my 585 has....Ed
that Rob has monoblocked in heavy rifled barrels, showing
the quarter sight rib he has made, fitted to the gun.
He has it chambered for 12GA FH long case.
Really beautiful work and gun.Ed
1.0" by 1.5" hole through it. It solves a big
machining problem for me in doing a 4bore.
And I happen to have some 1" by 1.5" steel.
The rest of machining I can do, and I have
the levers, hammer, trigger, etc. But the parts
and layout are not going to copy the Wickcliff.
To many problems with all the parts riding on the
breachblock and the crowded stubby extractor.
Will be my own design with hammer and
trigger behind breachblock. An extractor similiar
to Ruger and its shape a cross between WIN 1885
and a Farquarson.In pic you can see drawn outline
on the block of the shape it will have.ED
the 585 barrel, 32" long, 1 to 22 twist.
Chambered for my 585HE belted case.
I used a SB2 10ga action which is same as the 12ga
Ultra actions.I cut it off to make a 4" long monoblock.
and threaded it 1 inch by 14tpi. I'm going to do extra
ones 28GA FH,others.. My 585 is best 585,as the info will
show. I have a 45-70 extractor coming to rework for it.
I am firing first bunchs of test loads without
an extractor, and loads with 650 gr bullets at 2450 and
750 gr bullets at 2250 didn't need the extractor. They
come out with my fingers. Over 8000 ft lbs.I got thumbhole
stock now, because those with higher velocities of 2-400fps more,
were harder to hold on to grip. Trigger guard banged the fingers.
And higher velocity cases come out with a pry from my thumbnail.
Here is picture of rear of gun and the fixins(bullets/cases).
You see a fired case in the chamber, and I have cone breach
setup so that case is in same relationship to chamber as it
is in my three 585HE bolt guns. And is why I can get cases
out with my fingers.OR tip gun up. The hairier loads of
650 at 2650, 750 at 2450 is 10,000 ft lbs. Ed
how much does it weigh [?]
and a real thick soft pad.Don't kick bad.
Here's pic of my to be 4bore falling block with
the block to be the breech setting in the hole.
Breach needs trough on the top yet, but now
it is done for exact width and height and the
bottom recess and link hookup is done, since
the picture was taken..Ed
first models that were a scale up of the Wickcliff.
Complete new design, mainly in shape and type of stock
used, the bridge and reciever setup, and trigger/hammer
behind the block. Block will have no curved outside
shapes, front to back. Pics soon with the stock......
Used wadcutter style 8ga slug made by cutting off part
of a long nosed one in picture, in my 8ga with RE-17
powder.. Over 2300 fps. Slug is a zinc slug from kiln
gun factory load. With nose cut back and hollow I put
in the base it was 800 gr. It had a .20" wadcutter nose
on it.Good tribute to Elmer. The other ones in picture,
just with nose cut off and solid base and is 870 gr.Ed
chunk of shaft on front to simulate barrel to
get a stock fit.Got to profile barrel, thread barrel,
fit in hammer,trigger, couple bottom bolts into action,
design and mount extractor.. some springs, firing pin, etc.
May change/lengthen fulcrum on lever so it doesn't have to
move so far. Lever is held closed by little feramic magnet
in grip. Lever stays open due to weight of breach
block.Block moves smooth, no rattling around.
Rob- Guys-,I need some Vulcan V-50 thumbhole laminated stocks.
If there are any used extra ones around let me know.
This way of doing a FB in one piece thumbhole stock will work
for 12GA FH with an action 1/4" narrower.ED
breach down.You see bottom of breach block.The action
and barrel will be held in stock with 2 bolts into bottom
of action one bolt in barrel ahead of action and a recoil
barrel ring in front end of stock. Didn't have to add
any recoil lugs, as the wide back of the action is
the recoil lug. This is now called the Hubel Falling
Block Action. Second picture is of the 4bore cases
and 2000gr slugs, with 20mm case I make 4bore/ga cases
from and the 30-06 for comparison.Ed
BPI BPGS seals, Flexseal and sabot. Bret in
MN has, in a long heavy rifled barreled Savage
like mine, gotten 28-3000 fps with a 500 gr XTP bullet
in the sabot with a 3.5" plastic case. And it extracts
ok with the Savage bolt action extractor.
He is using slow shotgun powder, Alliant Steel.I can't
get that high in my NEF 12GA FH and make the
extractor work with the shot gun powder loads.
I get 28-2900, max amount much slower RE17 with 420gr
slug in the sabot.The case shown was fired with
RE17 load like that....Ed
700H 3.25" belted case to show the versatility
of NEFs and my 700. The 700 cal barrel monoblocked
like I did the 585HE. I put monblocked barrel on
the same SB2 frame that I have my 12GA FH on as
it has the beefed up firing pin for big primers
use in our 12GA FH case and in my 700H case.
Other projects coming.I found a heavy 16ga barrel
to monoblock in one to test the 16GA FH cartridge
I made. It is the 3.5" brass case mentioned
earlier in the thread.
Also a bunch of us are going to take 500 S&W
NEFs and put my 499 HE case in them, with just a
chamber job. It is a case that will get the zip
in 500gr slugs. NEFs are great guns to experiment
with and along with reasonable costs, we don't
have to worry about case length. Ed
