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

Rob shot Sat, just to see if they are stable. They seem
to be. He will do groups next few days. I'll have some in
couple weeks to test and do load development for my guns.
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

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

This has been an absolute pleasure to read. I have been interested in simular projects for years and recently have been following the Hastings' developements in the 3 1/2" 20 g. I am hoping to build a double 20 g. slug gun soon. Have you ever done any work on the 20 g.? Also do you know if there is any way of making 20 g. brass shells? Thanks

20 Ga. Brass Shot Shells
Try Midway for some brass shot shells.

Long brass cases, Rocky Mtn Cartridge. They've them done for others.
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

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
10-13-2008, 02:21 AM
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
10-21-2008, 01:27 PM
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

have you tried any of the new ballistic products BLS-12 Ballistic Sabots
they are saying their wad reduces chamber pressure allowing higher velocity
3" 2400fps 500 gr
3 1/2" 2700fps 500 gr
10-24-2008, 03:09 AM
they are saying their wad reduces chamber pressure allowing higher velocity.
I find it difficult to believe that reducing chamber pressure will increase muzzle velocity. If that is true, then try a round without powder (zero chamber pressure) but make sure you have a mountain for the backstop since it will be going really fast. :-)

should have said keeps the chamber pressure from spiking above saami specs
moves the pressure curve further out the barrel

I just got BPI sabots. Put in 437gr slug I rigged up.. Tested with my powders.
And because I was asked to, I also tested for comparison with
the HS-6 mentioned in those loads with 500gr slugs in chart.....In my Nef
I got 2200 with 437gr.. To get the speed in the chart with 50 gr of powder
you'd have to have over 90% powder efficiency. It would take a lot more
HS-6 than 50 gr ,but you couldn't keep pressures down to what a plastic case
or regular shotgun can handle. But my 437gr slug plus the 80gr of sabot and wads
at 2200, is 5500 ft lbs for everything coming out the barrel. Not too shabby.
Here is picture of RMC 3.5" cases with variety of slugs,
locked on wad slugs and sabots. There are 3 of our long cases
in back for comparison. The RMC turned cases have shotgun
primer. Case # 4 has 437gr slug in BPI SABOT( finally hard sabots
in 12ga for reloading), #5 437gr Brenekke KO slug, #6 540gr
Hammerhead slug, #7 600gr Dixie hard slug, #8 RG's 715gr
jacketed, #9 750gr solid brass. Ed

Here is picture of a 12ga hard discarding sabot you can get
for reloading, the BPI. From Ballistic products. In picture
is sabot with a 437gr Hornady Great Plains 50cal slug I put
in it. Also the 410 gr and 385gr Great Plains work.
Finally able to load your own instead of paying 3-5 bucks
each for loaded rounds.You can use the 500 S&W bullets also
as well as shorter 50 cal blackpowder slugs... Ed

Been testing the Encore with the Nef loads. Barrel breech is
one inch same as muzzle, where the NEF is 1.200".
It has dovetails cut out in bottom of the barrel for
the nuts for the forearm screws. ... At the bottom of dove tail
there is only .060" thickness. Before reaming had back one fill
welded as it was where the taper for the forcing cone ended up
with 3.5" chamber. I load it with 10 gr less powder than the NEF
on all different slugs and weights. Like the BPI sabot in 3.5"
plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore
110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug
in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500.
The Encore is now 12 lbs, with hollow in butt and recesses in
forearm with lead shot.In pic you see NEF And Encore with RMC
brass cases started in chambers. Ed

See what's possible, original Savage 210 action/stock
the one I have our long case in. You can lengthen
magazine in the plastic stock for up to 3.5" RMC brass
cases, also 3.5" plastic cases. And you can open up
bottom of the action to match, and the other things
I did on the port, bolt travel, etc to feed cases.
I did mine with heavy wood stock in singleshot.
Using original plastic stock you weight the hollow butt.
Trigger assembly on these is back to leave space for this.
In picture you see stock original and stock mag longer.
Second picture is a 3.5" brass case and slug overall
length 3.7", in longer magazine. Brett in MN, who did this
first used the regular follower and mag spring ok,
it feeds ok for him. .. Ed
