Testing 8GA FH in Enfield, 1050 gr slug in wad cup, 120 gr
of 4759, over 2000 fps. Cases extract easy. Hardly any
base cup expansion..Here is picture of a
sectioned 8ga plastic case I did,
showing how heavy and strong it is built. The
plastic is one piece compressioned formed and
the sides of the cases are twice as thick as
12ga cases.You can see the double thickness
of the base cup. Ed

Here is picture of the bolt setup for the 8ga
Enfield we did.Also comparison to a Mauser
12ga shotgun bolt conversion, from which
I got the concept. Ed

I was asked how I got 8ga heavy barrel so quick.
First it is smoothbore, second a 110 bucks total shipping and all.
First I bought a 1.5 inch dia 4130 alloy, heat treated, shaft,
32" long. Then I had a deep hole drilling company drill
a .832" hole in it. Came out centered on both ends.
Then after it got here I used cylinder hone to polish
the inside of the bore. Threaded it, chambered it, and put
in the Enfield bolt action. The heat treating it has is just like
the barrel stock that barrel guys get. Ed.

For those wanting to see video of the 12GA FH in
the Savage busting big pail of water, one of the
kids posted it on Youtube- Titled "Grampa's Cannon".
I just found out that it is on there.
This was the video that the still pictures posted
before, was taken from. They have the sound
muted so as not to hurt camera sound system. Ed

Here's the link to the video for anyone interested: http://youtube.com/watch?v=rUNHszY4ACM

Interesting to see a 5 gallon bucket do a vanishing act!

Load of 12 triple ought buckshot in 8ga. They are
70gr each, total 840 gr, and over 2000 fps with
125 gr of 4759. Ed
Thanks for URL for the waterpail busting video.

There are now two videos of 12GA FH on YouTube,
exploding big heavy walled pails of water.
The "Grampa's Cannon" one with a long view,
and "Grandpa's First Shot" a closeup video,
the first one, that shows how the top of heavy
shelf got bent. Later kids will do videos showing
muzzle blast and recoil.
Also the 3 ought buckshot from the 8ga load
above goes through 2" hardwood ok. I will test
8ga on waterpail also, to see what happens. Ed

Got my long 700 HE case chambered barrel
finally in a bmg size action. It is barrel
I locked onto an I-beam and got testing and
load developement done over the last couple
years. Max load about 23,000 ft lbs.
It weighs 27 lbs, laminated thumbhole stock,
a max size pad, weighted butt, a reinforced
wrist, recoil barrel ring on front of stock.Ed

Here is picture of a neat scaled up Sharps replica
that would handle out 12GA FH and my 700HE.
That outside hammer looks great. From a magazine
article in Very High Power...Ed

Here is a pic of a projectile idea Rob had. We will test it later
this fall, It is 12ga bore rider design Body is Aluminum, and it
will have a heavy 50 cal insert in the nose made from tungsten
or similiar metals. In the picture he put a 50 cal bullet in for
show. The insert in the nose will be flush with front of the
AL carrier. It should be stable at slow twists and if built
with back and front same diameter stable in smoothbores.
The long lighter tail-end compared to heavy nose insert
will make it stable. Same principle Brenekke uses. This idea
is being explored to try to get superior penetration
from 12ga, with heavy, hard insert in the nose.Ed

Here is another view of my 700HE blaster,
that I got rigged up on an action and stock.
Side view shows action with a aperture sight I
rigged up. Also cases. On left is 700H 3.25" case.
Center my 700HE, what the gun in picture has now.
Good for nearly 23,000 ft lbs, we attained in
a work up in testing with the barrel as a test
barrel with screw on testing receiver....Ed

Here is picture of another dart type 12ga slug Rob made. Body
is aluminum, it has a heavy tungsten carbide insert in the
nose. The TC in the nose is about 5 times denser than AL.
Total length is 2.35 inches, weight about 950 gr. The .75" long
insert a real tight type fit. Heat AL, put in insert, cools, locks on.
It is fairly streamlined, yet has wide meplat for penetration
in game. Flat points penetrate straighter in game.
It is hollow inside in the back, behind insert which puts the
center of gravity way up front, it should fly straight even from
a smoothbore. They are fast to make and material
less expense than copper.In pic is a copper and a brass 600
cal slugs for comparison. Dart/slug on right has insert.Ed

Tungsten tipped?

In case any wandering main battle tanks start poking around the garbage?

Here are more samples of nice 12ga slugs.....Here is pic of
ones RG Henson sent. Jacketed 12ga. 715gr hollowpoints,
on the right and in front a jkt 675gr hollowbase.
RG's number 1-770-366-4846. These will be great for
shorter plastic and brass cases as well as long cases.
Other slugs in pic, in the back, left to right
Foster 436gr- Dixie 600gr- 750gr brass- my 750gr hollowbase
brass, and a hollowpoint I put a lightweight filler in the nose
for streamlining..Ed

hubel458 · « **Reply #138 on:** September 16, 2008, 08:31:01 PM »

Two other 12ga slugs RG may do later on are full
jacketed ones. If interested in the hp one above
contact him at number above. He has to do a bunch
of them to get ahead to do others.And they will be
a fantastic deer, hog, bear slug. He is in Georgia.
Also, any of you who might want some of the 12GA FH
brass cases made from BMG brass, we have the fellow who
had the idea about the 12GA FH first, Rob on AR forum,
is planning on making them. He has got the machines to do
it now, that we didn't have before. Let me know how many
you are interested in getting, so he can plan and figure
the best way . He has a bunch of BMG cases to start with,
he and I have places to get more.I'm posting this all over.Ed

kevthebassman · « **Reply #139 on:** September 17, 2008, 01:56:15 PM »

Ed, if I were just interested in a single round with bullet but no powder (purely as a novelty item) about how much would it run me?

hubel458 · « **Reply #140 on:** September 17, 2008, 05:40:44 PM »

12 bucks shipping and all. And once he is making them I'll get a
bunch to take care of the collectors. Tha is how my supply of
them went away..Ed

Testing 715gr jacketed hollowpoint from RG Henson in Savage 210.
With 30 inch barrel, long brass 3.85" case, big primer.
Slightly hairy load 290gr RL22--2700 fps. Shot moderate load
of 300gr W-860 -- 2400 fps for 3 shot group of 3" at 50
yards with my bad eyes and peep sights. They shoot nice, they go
into target straight.. Other nice thing the price from RG,
for customers getting in on his first run, $1.25 plus shipping.
That is less than half of what other big bore jkt bullets cost.
Call him for some great slugs. They are great like
the Dixie slugs. Ed

hubel458 · « **Reply #142 on:** October 01, 2008, 05:34:07 PM »

Lookee what another santa sent me.
A regular BMG case on the left, and
a straight BMG case on the right, and it
CAME FROM THE MANUFACTURER THAT WAY.

It is primer cartridge for large guns and howitzers.
It is used in those guns/cannons that have powder in big bags.
It is filled with powder and inserted into cannon breach and
when fired sets off the larger charge. On some cannon breaches
they have an automatic feed for these with a huge 40 round
drum magazine. This on is marked IVI 89 C67. IVI is Canadian.
On these breaches it is held by collet fingers for head space
and for ejection.

Ok, there are many thousands more of these out there than the
PROP cases I showed before. We need to find few barrels of these
and have Rob, etal, put on rims.... no annealing.....no fireforming,
just slight resize to 12GA FH. Please help if you know of any.
They would save so much work and time..And even though fired
the bases are perfectly straight, another plus.....Ed

Here is a picture of RG's jacketed 715gr slugs in various
loads.First are 2.75" and 3" factory foster slugs\ for
comparison. 3rd is jkt HP in 3.5" plastic case, 4th in a
3" brass RMC case. 5th in a 3.5" brass case with small
primer, 6th in our long brass 3.85" case, big primer.
Top hairy load in long case in Savage, 2900..Ed

hubel458 · « **Reply #144 on:** October 12, 2008, 05:27:18 PM »

Please notice in the picture above, cases loaded with
the 715 gr jacketed slugs, the 3rd and 4th ones.
They both have same 90gr of 4227, same number of
wads, shoot at 1700 in 24" NEF barrel. 3rd plastic is
3.5" case, the 4th brass is a 3" RMC. Both have shotgun
primers.The 5th longer case is a 3.5" strong
brass one I made from a PROP case, and when I put
in primer bushing, I set it up for shotgun primer. I
will test it with 4227 powder, 600gr and 715 gr slugs.
Also in a couple months Rob, who's idea the 12GA FH
was will be able to deliver the super strong 12GA FH
cases made from BMG brass. And the they will be
headstamped, all done by his CNC machine.Ed

RIP on AR Big bore forum is doing 835 Mossy and 1400gr Darwin slugs.
A 14.5 pound Ulti-Mag. The hollow part of the butt is filled with about 5.5 lbs of lead shot and epoxy. Has 4X Sightron in QRW rings. Do 3.5" plastic hulls with the Darwin in it first. It balances on the trigger. Loading the magazine with 4 and one up the spout will add about 1.25 pounds if the 5 rounds are "Darwins," and move the balance point to the front of the triggerguard.
It is heavier rifled 24" chromoly alloy barrel.

Brett in MN has Mossy 835, only with smoothbore barrel and gets
1oz finned plastic tail Ballistic Products slug to 2300 fps,
using shotgun powder.Ed

Still testing 8ga I have setup in the Enfield.
It has a long smooth barrel. Those 8ga
heavy plastic cases are great. Fire them 4 times with
no resizing. Here is pic of slugs used in 8ga..
One and two are 1015gr hollowbase. Three and 4 are
875gr hollowbase. On four the cushion base is cut off
so I can use card wad and have more room for
powder.Ed

WE test both plastic and brass 3.5" cases to compare.
We got our RMC 3.5" brass 12ga cases. These are turned
cases using shotgun primer. They have nice thick base,
and a good radius in the corner. Got a Brenekke OK 437 gr
slug to 2800 fps, a 540gr Hammerhead slug to 2450. got 600gr
Dixie to 2300, the 715gr RG jacketed to 2130, and a 1400gr
Darwin to 1400 plus. Tested in NEF. Shot one case 15 times
and still going strong, tight primer, with loads running about
20- 24,000 psi.I have pics of cases soon, and we also will
test these brass ones and 3.5" plastic in 12ga Encore
Prohunter..Ed
