There is an exemption for shotgun calibers firing shotgun
straight sided cases. Cases can be any length as long as chamber
fires shorter shotgun cases, Cases can be paper, plastic, brass,
steel,aluminum, any length.You can't take a 40mm and neck to 12ga
and call it a legal 12ga.As it wouldn't chamber and fire other
12ga cases.Can fire any projectile that doesn't carry
explosives. Barrels can be rifled, smooth, polygonal, smooth
chokes, rifled chokes, partly rifled at the end(Paradox).
They are exempt in Title 18, GCA, Section 921.
Otherwise about 10 million deer/hog hunters with riifled
barrels in various shotgun calibers would be in jail.
If you made a 12ga bore size cartridge from say a 40mm
you could still own it, just register and pay the tax; or
get a sporting exemption under the same Title 18, GCA.
Non shotgun calibers over 50cal that you don't register/pay the
tax on, have a sporting exemption, llike 577NE, 600NE,
700NE, 600JDJ, 600AHR, my 700HE, many others. ..Ed

Some more BPI seal and sabot testing.
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

Here is picture of the breach of 8ga FH NEF with
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

Here is picture of a 12ga size drawn brass case that was
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

Here is picture of a NEF breach barrel section that I threaded
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.

I fired mono-blocked NEF this week with a 585HE 32"
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

Here is a picture of the Zabala that was a 10ga double,
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

I found odd steel block with a square cornered
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

Here is the finished NEF mono-blocked gun with
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

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

The falling block is coming along. I'm not copying my
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

We don't overload, we load for the gun and barrel
combination we buy or put together.Ed

Another couple months maybe 4 bore/ga will fire.Just have a
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. Checking on different shapes for lever. When breach is
lowered the lever stays open due to weight of breach
block. Block moves smooth, no rattling around.
Guys-,I need some Vulcan 50cal 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 about a 1/4" narrower.ED

Here is picture of 4bore/ga action with lever open and
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

Here is picture of the 12ga wad column using two
BPI BPGS seals, Flexseal,cork, 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 Alliant Steel powder loads.
The NEF handles pressures fine, just doesn't extract
like a bolt action Savage 210. Using RE17 without cork,
I get 28-2900, with max of much slower RE17 with 420gr
slug in the sabot, in NEF The case shown was fired with the
RE17 load like that....Ed

Here is picture of NEF I've set up with my
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
