Here is picture of a falling block a guy on Weaponsforum
has picked up to finish. The fellow who started building
it laid it aside for awhile and the new guy is going to finish
in BMG. It has 50cal bbl on it. Looks easily big enough
for 12ga,10ga,8ga, my 700s. The lever on left is cocking
mechanism, The tube in back is a firing striker and spring
and it hits the hammer block you see in the back of the
breach block, which hits firing pin ahead of it in breach.
It is the the only one like it. They've put a lot of work
into it, especially the hammer block striker setup.Ed

In related big bore work we got a Montana Rifle
Co, PH action setup in my 700H 3.25" case. Fired
test load of 825gr at 3000 fps. This was just one
test load. Normal max loads are 825gr at 2850 and
1000gr at 2700.Hunting loads 24-2500, First PH fired
outside the factory.It is in first picture.
PH will work for any big case and my 585HE.And
if anyone looking at big actions for 12ga FH,
here is picture of MRC PH with a 3.5" 12ga case
partly into action. The PH cam be used for 12ga with
action and rails opened like I did my 700H in Enfield.
And a little changing on the bolt face and extractor
In 12 ga it still would have 60% of front lugs contacting
and you'd add bearing lug surface to bolt handle base so
it would handle same pressures as Savage 210.
And 3.5" with average length 12ga slug would feed from the
magazine. Our longer case would work with port opened
and some mag work. Ed

Got single stack mag figured out for 12GA FH and
my 700H 3.25 in PH. I fit a bolt action 12ga
box mag and its follower and spring
inside the PH mag box. Easy to fit in metal box,
and permanently mounted to metal and floorplate.
Holds 2 down. That way feed lips already a working
design. And opened back of 12ga box for longer case
like I did with my 700 in Savage 210. Also work
for anyone doing a PH in 12ga FH if they aren't
loaded too long or with 3.5" RMC cases. Using most
cast 12ga bullets like Dixies, the overall length with
3.5 brass is 3.9" and fits 4.05" box ok. Here is picture
PH from bottom showing its big size.You can see in pic
there still is room to make box longer yet.
And the feed port can be longer.Montana Rifle has
great action here with lots off room and strength.Ed

I got barrel on the 4ga/bore falling block gun.
Barrel 32" long, 1.87" breech, gun is 27 lbs.
Notice breech block is down and huge hole in barrel.
Maybe shoulder cannon is the right term for it.
It is all inleted into thumbhole laminated Vulcan
50 cal stock, of which I need more, if anyone
knows where there are any. 4 bore cases shown,
next to the gun, 2 with 2000gr slugs,
and I'll use a big ammomaster press for them..Ed

Here is a picture of the front end of the 4bore,
showing a 2000gr slug protuding out. Simulating
stop action photo work, as if anyone wwould be brave
enough to put a camera out in front of it
when it fired. Will have it firing by fall.
I plan on using hollowbase lead slugs of
about 1600gr, as it is a smoothbore. Ed

got 3" chambered 12ga set up to test loads with RE-17.
Many guys want loads for 3" chambered slug barrels as they
come from the factory., So I put extra 24" Savage barrel I had
on a Mauser GEHA bolt action. Rifled Savage barrel is modern
steel with .93" muzzle diameter. Original barrel on the GEHA
was only .82" at muzzle. I added an extra rear bolt locking lug
onto the Mauser bolt. Using up stuff to make test gun.

Any modern steel slug barrel, whether on bolt, autoloading,
pump, or break action gun with same muzzle diameter will handle
these RE-17 loads. Max loads were all 115gr of RE-17 in plastic
3" cases, all with seals and cushion wads. Can't get no more under
the seals, cushions and slugs in 3". Which is why I like 3.5"
chambers. With 437 gr Brenekkee and 420 gr in BPI sabot got
over 1900. With 520gr Lyman in shot cup 1850. With 600gr Dixie
got 1800. With 870 gr hard lead got 1600. This is 24" barrel,
so longer barrels will get more. In comparison to IMR4227 loads,
these are about the same speed as using 90gr of 4227. But this
powder is so much easier on cases and guns, with about .004"
less base cup expansion. It works great in 3" and really gets the
speed in 3.5" cases, as in 3.5" cases,as seal/wads about same,
extra length for powder. The 870gr load is max peak pressure of
16,000 psi. Muzzle pressure is about 3500-4000 psi.
I'll have pic of the Mauser in few days.ED

Here is picture of my 695 Mossberg bolt action.
It is 28ga FH, a 3.25" long brass case. Was a
12ga with light barrel. I also have a heavy 12ga
barrel chambered for 3.5" cases and a .500" barrel
for my 499HE a real long brass case. Also I am
doing my 499HE in a NEF. You can get a NEF with
MMouse 500S&W and run my reamer in and get real
power.The 395,495,595 actions will work also,
as they like the 695 have double bolt lugs
and a loading port that can be lengthened.
And they have a nice style...Ed

We get asked about finned slugs for
12ga smooth bores and if they take high
speed. Well they'll do just as good at high
speed as the locked on wad stablized Brenekkee
OK slug I tested in my smoothbore 1887 with long
barrel, in first pic. Second pic is a Corbin
finned slug I will get and test later. Third is
BPI AQ slug I will test, few weeks in the 87.
I'm going to test also in a regular smooth bore
12ga slug barrel of medium muzzle size,
about .92" diameter like the Savage 210 barrel.
One gun I found with decent size diameter are
some of Stevens smoothbores..Ed

Here is picture of the Mauser GEHA shotgun I
setup with an Savage 210 rifled barrel. Used a Savage
plastic stock also. It is setup with the original 3"
chamber. I have many guys who want ideas and slug/load
combination's tested in regular rifled slug barrels, so
this is the one. Most testing will be 3" plastic cases.
Barrel 24" long, .93" regular slug size muzzle diameter.
The GEHA was originally converted from 98 Mausers in
Germany in the 20s, to 12ga by reaming outl the front lug seats
and using the rear safety lug. I added a second rear
bearing lug and it handles 15,000 psi loads ok.
The cases come out with the weight of the bolt.
That will be max pressure used in it, with that slug gun
barrel thickness. Example load is 115gr of RE17 in 3"
plastic case, with 520 gr Lyman cast slug at 1850 plus fps.
This load expands the plastic case base cups about .005",
in comparison, a REM factory Buckhammer and other super
mag turkey and goose loads expands .010".
And we have over 300 fps more velocity.Ed

Testing some .660" diameter 630 gr hard cast
slugs in the red WIN wadcup in 3.5" plastic
case. Tested in rifled long barrel in 12ga
NEF about 2100 fps. Greg Sappington makes
these. They are hollow point. 3" group at
50yds, peep sight, bad eyes. I also fired
a couple to see if they'd work in my long
brass cased 16GA FH shown in the picture.
They work ok, so Greg has a double duty
slug.They'd work in 16ga plastic also.
The 16ga was held at 1500 as the barrel
isn't heavy, on Stevens/Revelation 16ga. Ed

Comparing brass cases.I tell folks who are stepping
up in 12ga power from 3.5 plastic, you can get 3.5" brass cases
from Rocky Mtn Cartridge. Here you can see how heavy
and nice they are compared to regular brass cases.
They also make shorter 3" brass cases also.
They fit the chamber tight and are long enough to
get some serious thumping power.And they have a
super strong, thick , solid head, not a weak balloon head
like regular ones on the left in pic.Ed

The ones I got are just stamped 12ga.They may
do any headstamp you want.

Tested my 499HE in a NEF. Loads I didn't have to
full length resize the case, only top 1/4 of case.
325gr at 2600, 500gr at 2150.
In NEF got both weight bullets 300 fps faster,
still extracted very easy.I got reamer. Just run it
in NEF 500 chamber and you got a blaster. And add
a little weight and thick pad to the gun.I have
a barrel ring to hold forearm along with original
bolt, as I added weight there as well as the butt.Ed

Finally an 870 with longer 1" muzzle barrel. Barrel
is heavier than most all add on pump gun barrels,
and it is 25.5" long, Something that would really get
it on with the slower powder loads we have.
Rifled barrel is solid mount in receiver, scoperail solid mount.

It is the REM 870 Super Slug Gun.
Nice long heavy barrel, and thumbhole stock for
handling recoil better. Plastic case 3" slug loads of ours that
gets 600gr slugs to 1800-1900 fps, work great in this
Like the ones I load and roll crimp in second picture
that are setting behind the little vise, and the one in the
vise ready to be crimped...Ed

Here is a novel slug idea, hard plastic support ring on
the front, and a locked base ring/seal. Metal never
touches the bores. Work in great rifled and good in
smooth barrels. These are steel, lead/copper would do
great also.Could be made heavier and different points.
Flat point shown would do great damage to game.
On the net- ammunitiontogo.com
This one is about 500 gr.

Second picture is the 499HE to use in redoing the 500S&W,
shown on the also, in single shots, etc,for those wanting
much more power at 40-50% lower pressures.Ed

Some more testing with RE17 powder. I used it in 2.75",
3", 3.5" 12ga plastic, 3.5 and 3.85" brass. I like it the
best of all, as well as the real slow powders in our
long case with BMG primer.
Following tested in Savage-max pressure 35k psi.
I took couple of our first made 3.85" BMG based
long cases and bushed them back to use shotgun primers
to fire off the RE17. Works great, with 715gr jacketed slug
and 220 gr RE17 getting 2700 . With 420 gr slug in
BPI sabot with 250 gr RE17 getting 3200 plus.
Following tested in NEF-max pressure 25k psi.
Using 3.5" MRC brass, 715gr jkt and 200gr RE17, got 2500.
420 gr in BPI sabot and 220 gr Re17, got 2900 fps.
And we get real good velocities in plastic with half the
basecup expansion of factory mag loads.So that solves
problem-IE, being able to use regular firing mechanisms and
shotgun primers, with large enough powder charges to
get hairy velocities at mag shotgun pressures in plastic
and higher in brass cases with heavy barrels.A good powder
for plastic and brass loads.
I see now that Lightfield Co has the Commander 3.5" Plus
slug loads with 600gr at 1900, probably in a test barrel.
But that is great- nice, as it seems we're being copied!!!ED

So many guys want 12ga sabot type slugs to reload their own.
Here is an interesting combination slug available in Europe
and they are working to get distributors/stores here.
Any interested stores and shops contact them. We need
many sources of saboted slugs for reloading. The sabot
petals discards completely as slug exits muzzle and locked
on base stays with slug, making it nose heavy so it will give
decent accuracy in smooth bores.Will work in rifled barrels
also. Slug is .629" diameter, comes in 570gr, 700gr, 970gr
weights. They're selling these reloader/other loaders only.
It is called the US-S slug, and their site is
europeancartridgeunlimited.com ..Ed

The company kindly gave me few US-S slugs to test at high speeds.
I had helped him test another slug a while back.
He sent me some each of the US-S 570 gr, 700 gr, 970 gr.
I tested the 570 gr so far and in 3.5" plastic case in the 1887
smoothbore 35" barrel and in the NEF rifled 36" barrel at
1900 fps. I got that with 130gr of RE17 with one BPGS
seal under the sabot on the slug. The bottom of the sabot seal
is exactly like a BPGS, so a BPGS added gives double sealing.
Both smooth and rifled gave 3 shot 3" group each at 50 yds with
peep sights and bad eyes. This slug does as good as advertized
in smooth barrels, and smooth accuracy is as good as rifled.
My smooth barrel is tight, measuring 723" at muzzle.
These should be a great deer and hog slug. Folks need to
ask their dealers to work to import these for them
to have what seems a good slug to reload...

On another note we may have found a guy who is gearing up
to make 10 ga rifled barrels. I'll know later this winter
If so I will put one on a bolt action and use the 4.1" long
10GA FH case I made or get some like it from RMC..Ed

Here is picture of the US-S slugs in a lineup
with other 12ga slugs I'm testing. Lefteris was
kind enough to send me a few of each weight
to test. They are the 3 in second row on the right.
They are 570gr, 700 gr, 970 gr. I tested 570gr in
3.5" plastic so far. At 1900 in the NEF rifled, and
in the 1887 smooth barrel, got 3" group on both.
With peep sights an bad eyes.So the US-S slug
is great in smoothbores, as good as rifled. My
smoothbore on the 1887 is .723" bore at muzzle,
a nice tight fit for smooth slugs. The smooth
bores Lefteris tested them with are .722" muzzle,
and they've already killed 5 wild boars, one shot
kills with the 570gr slug. Also if anyone wants a
heavy smoothbore new 12ga barrel, .722" muzzle,
1.375" outside diameter to make a great slug
gun with slugs like these, and others like the
Brenekkes, I have spare one. The US-S slugs
are smoothbore accurate in my 87 like the
Brenekke KOs.In the picture the left two cases
are 3.5" Fiocchi with the Fiocchi magnum primers.
I compared that primer to the REM 209 primer and
it has about the same strength.Next two are FED 3.5".
then 2 12GA FH 3.85" cases, then 3.5" RMC brass, then
3" RMC brass, the 2 WIN 3.5", then 2 REM 3.5".ED

I got the 700H 3.25 case feeding from the magazine I set
up on the Montana Rifle Co PH action. It is singlestack with
feed lips similiar to 12ga shotgun clip style magazines I
had here. Works great, shown in first picture. Now it is longer
than regular 12ga mags, but same setup would do for feeding
long brass 12GA FH and long MRC 12ga cases. The
700H 3.25 is 3.9 inches overall loaded length. In picture
case is ready to clear the mag lips, then rim pops up under
extracter as bolt is moving forward. Second picture is
the box used that I made out of two PH boxes. That allowed
for extra height and fit for singlestack and riveted together.
Used a Savage 210 12ga follower and spring. ED
