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

http://www.gunownerstv.com/gregsl.jpg

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

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

http://www.gunownerstv.com/499nef.jpg

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

http://www.remington.com/images/prod...r_slug_780.jpg

http://www.gunownerstv.com/drill.jpg

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

http://www.ammunitiontogo.com/catalo...nolit%2032.jpg

http://www.gunownerstv.com/499he.jpg

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

http://www.europeancartridgeunlimite...P7190013_s.jpg

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

http://www.gunownerstv.com/usslug.jpg

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

The 700gr US-S slug in smoothbore, at 2000
in a 3.5" brass case, got a 2.5" 3 shot group
at 50 yds. Great slugs they have come up with
for smoothbores.
Some of us talking about getting 10 ga rifled
barrels made, here is a picture of my 4.1" long
brass 10ga I made from 50cal Russian by putting
on a rim like the 12GA FH is built.Just a prototype,
third in picture. Later I'll get RMC to make some,
as it is much easier way. First in picture is
16GA FH 3.5" long, 2nd 12GA FH 3.85" long,
3rd 10GA FH 3.1" long, 4th 8GA FH 4.3" long.Ed

http://www.gunownerstv.com/10gafh.jpg

Here is picture of the 12ga belted cases I made to
test a few loads in. I made it from 55cal belted
Boys case. I reduced belt diameter a little and left
the base the same, which is 12ga size.In picture
first is 55cal, second expanded to .620", third
expanded to .660"(16ga), then two 12 ga ones.
Next is our 12GA FH, and then a 12ga 3.5"
plastic case.A little work in long 12ga FH chamber
with a tool for belt step and it chambers. Ed

Here is a picture of US-S brass slug after going through
3 foot of wood slabs in a bundle. It has shed its plastic
base and it went through straight without tumbling.
This one is 570 gr fired at 2200 in RMC case, from NEF.
Also in picture is one with white sabot petals off, as it
would be in flight, before hitting target.Ed

4bore work. Working on design of firing pin,
and waiting for parts now. Problem is getting
real small parts without CNC for bushed
firing pin with rebound spring. But it takes
time.

We will have swaged lead slugs
in a little while as my barrel is smooth. They
will be 1600gr hollowbase, when done,
a hundred of them at least.
Got wads and cards, shown in the picture with 4bore
cases and slugs. And my 2bore case for comparison
Also 12ga wads for comparison..Ed

Our cartridge work and experimenting got a nice
write up in # 470 Nov/Dec International Ammunition
Journal. Page 10-11 by Zach Weighman, a
cartridge collector and gun nut friend.

Got a guy just figured out BMG case rim, and for a rim
puts on 12ga high base cup from a plastic case. He turns
base/rim of bmg case about .008" and use JB Kwik to hold
it on. Pushes it on with press. He removes base cup with
heat gun from plastic cases,

He is using RE17, so shotgun primers will work, and he
puts bushing in case for primer. Has bushing reamed so
the primer pocket protrusion on the base cup goes up inside
tight, as he pushes on the base cup. It'll fire ok and to size it
do like I do, I push case into open top die, and push it
back out from the top with a rod and hammer. That
way the rim don't get bent up. He says it saves a lot of
time not having to make rim pieces.

We will have more info and pictures next few weeks.Ed

Here is a picture of a BPI sabot with a BPI Flexseal I
use on to it in place of the original cushion seal.
I also cut shallow slots in the outside at the bottom
of the petals. Sabot opens much quicker and seems
along with BPGS seals under it to work ok without
damage, giving high velocities. In pic on left is regular
BPI sabot, behind is one I put a cushion on from a
Brenekke KO slug, and in front the one with Flexseal on.
The slug in it is one a guy casts at 440 gr and .504"
diameter, and works ok.

New info on my 499HE, from now on we will make cases
out of 450 #2 brass, as Jamisons has 3-4000 cases,
and it seems no one has the 475 #2 we used first.
Only slight case dimension change is the base .012"
smaller, all else is the same. I'm getting reamers redone
and will be able to use in couple weeks. Case will still have
plenty of taper to extract easy in singles, doubles,
falling blocks.etc.

And speaking of falling blocks I found one, and put my 585HE
in it, and it is big enough and has enough clearance to be used
for a 577NE, 600NE, long 20ga, my long 16ga FH,
the 700H, the 700HE. Cost no more than Ruger, with barrel
figured in. Will have pics
and info soon. Ed

http://www.gunownerstv.com/bpifl.jpg

Here is picture, Falling Block I found that I put
my 585HE in. It didn't need any work on the
feed trough to feed. 585 case shown in it.
In fact the trough is big enough
and the action big enough for 600NE, 3.5" 20ga
brass, 3.5" 16ga FH brass, my 700 HE long case.
I reworked a NEF stock to it, as I'm not
a stockmaker.Nice action.2nd picture is
of the 16GA FH in the feed trough.Ed

http://www.gunownerstv.com/nfb585.jpg

http://www.gunownerstv.com/nfb16.jpg

Here is picture of the FBW falling block with my
700HE long case in it.This falling block is 1.5"
wide, with a 1.125" wide breach block.
The sides are .187" thick next to breach block.
This compares to about .165" say for a Browning
B-87, Win copy. The feed trough would work with
12ga size rim if some work was done on the top
of the hammer. This has a barrel thread length of
1.005", thread diameter of 1.125" for good
strength. Ed

http://www.gunownerstv.com/nfb700.jpg

Here is picture of the falling block with a
600NE in the feed trough. Work great
chambered as a 3.5" 20 gauge, for
20 gauge 3.5" brass and plastic cases also.

Second picture is a 12GA FH case we made by
epoxying on a 12 ga base cup onto a bmg brass
case. Turned brass down .010" and pressed on base
with epoxy in it and when set base is on good.Ed

http://www.gunownerstv.com/nfb600.jpg

http://www.gunownerstv.com/12bases.jpg

Another way that I put a 12ga rim on
bmg case is to use the new Magtech brass
12ga cases made by CBC in Brazil.
BPI and others sell them for less than
a buck each. Being so short they aren't
in the 12ga FH category of generating power.
But you cut them off a quarter inch long, and
turn a BMG rim down to .715 diameter, push on the
Magtech base, with JB weld in the Magteck
base, and set up a squeeze collet to
crimp the Magtech base sides into the BMG
extractor groove. Crimp it in hard and tight.
And it uses large rifle primers.Fed Mag 215 best.
Other bmg case work needed is to put a chamfer
on the bmg primer pocket and drill out the
bmg primer pocket straight so that there is no
block to the primer gases coming out through the
Magtech flash hole. Chamfer back of rim a little.
These will handle
20,000 psi loads.Ed

Here is picture of Brett Ittel's Savage 210 he has setup.
It has a 3.5" 12ga chamber in a heavy 27" Pacnor barrel,
that he put in place of original. He also put in a Knoxx
spring/cam recoil absorbing butt plate in the hollow
Savage plastic stock. He replace the plastic parts of the
absorber with aluminum parts. It is shown without the boot
so you can see how it is in the butt.He also has an oversize
pad on it. He hasn't weighted the gun with anything else and
it shoots comfortable, even off the bench with loads that get
a 500gr slug in a BPI sabot over 3000 fps. He gets this speed
with BPI and 500 gr in 3.5" plastic cases. He also can use
3.5" RMC cases and our BMG based case, cut to 3.5"...Ed

http://www.gunownerstv.com/bret.jpg

Some 8ga work.I found a way and made a die that
swages the 8ga kiln cases down to regular 8ga size.
It swages the belt down and a turning tool I made
removes the sharp edge on the belt after swaging,
to make a smooth transition to the right size.
It does it 4 times faster than previous process.
My chamber on the NEF is set up so regular sizes fit
and loaded kiln cases with the belt step won't go in.
It works with both the REM 8ga cases from BPI and the
WIN 8ga cases from Precision Reloading, and the
WIN cases are only 44 bucks a hundred, primed.
The WIN cases have the same extra powerful primer
just like the REM cases. The REM cases are black
and the WIN cases a see through plastic. Both same
thick sides.Anyone needing cases worked over
contact me... Ed

A switch barrel auto we are tested 3.5" 12ga
smoothbore USS-S slugs, with hopped up loads.
About as accurate as the other guns here. Also
I'm getting the auto set up in my 585 HE long
case.585 HE long case shown in the port.
Switching barrels only takes minutes. This 12ga
barrel about as heavy as the 210 Savage barrel.
It is originally a 3.5" 12ga autoloader I've reworked
the stroke and have a barrel extension coming to add
585 28" barrel. Gun is weighted, thick double pad.
We are going to see how mild 585 HE loads of
9,000 ft lbs work in autoloader.Ed

Guys have asked about a 10ga FH, and it is just
getting stuff to do cases with reasonable time and cost.
So a breakthrough with a 10ga FH, is putting 10 gauge
basecups from plastic cases onto 50cal Russian brass to
make a 4.05" long 10ga. I expand case using my shellholder
on original rim, put in bushing for shotgun primer, which
fires off RE17, the turn case and rim a little, and slip
on basecup with epoxy inside. Then take a 200 dollar heavy
barrel NEF 10ga, and deepen chamber like mine is.
Here is picture with one beside a 12ga FH. The 12ga FH holds
max load of about 330 gr ball powder below a slug,
and the 10ga FH holds 420gr. I'm getting things set
to get a bunch of cases to do this. Progress.
Now anyone wanting any of my cases for their collection
I have a package of them all. Contact me.. ...Ed

http://www.gunownerstv.com/10gafhb.jpg

Here is a neat idea for a 5 shot 12ga,
a 12ga revolver. Nice looking gun.
Also I found a company that would rebore 10ga
NEF heavy barreled guns to 8ga, if they can
get 5-6 guys lined up to do it, so that they can
make tooling and charge less than
300 bucks to do it. Delta Reboring.
Let me know and we'll get arrangements made
if enough are interested.I have two now.ED

http://www.gunownerstv.com/zrevolver.bmp

The long brass 10GA FH case shown above has a Lyman
slug in a thickwall 10ga steel shotcup that BPI sells.
That's a 12ga 525gr Lyman.Makes nice lighter slug for 10ga.
The slug has bottom chamfered to set in cup tight
and a little epoxy makes it one piece that makes it a discarding
sabot style like a SPW. That makes it front heavy so that it
is as accurate as Brenekke KOs in smoothbore. I'm
also working with a guys to cast long hollowbase 10ga slugs
like the ones Federal loads. We are figuring out molds now,
will probably make slugs about 850gr. Here is picture of
my 10GA FH NEF with long brass case started in the chamber.
Chamber is set for that 4.050" brass case and will shoot 3.5"
plastic cases also. I am going to put on a thumbhole Survivor
stock like I have on NEF 8ga we did.Ed



http://www.gunownerstv.com/10gafhbg.jpg

We talk about liking the use of heavier slug barrels
in using our slow powder giving 1/3 faster loads
in plastic cases, and handling recoil better. It is
stiffer being heavy for an aid to accuracy.
Guy out west has this heavy muzzled, Hastings, rifled
barrel, for his REM 870. In first pic is a comparison to the
original 870 barrel. It shows a muzzle as heavy as on
a NEF Ultra Slug GUN. 2nd picture is the gun itself.
That makes a neat slug gun..Ed

http://www.gunownerstv.com/maw1.jpg

http://www.gunownerstv.com/maw2.jpg

The heavy rifled barrel in previous post was made by
Hastings for the Remington 870. It is 26" long and a
muzzle diameter of over an inch. Hastings is gone now,
but we'd like to find some of these barrels. The Hastings
number of the barrel is 560H90.

In the meantime Remington has come out with their
SPS Super Magnum Slug Gun with 25.5" rifled barrel and
a 1" diameter muzzle, with more solid barrel, and extra
pins in mounting barrel, so a scope can be put on action. Ed

http://www.hyattgunstore.com/images/P/main-1933.jpg

I get asked about presses used for big cases.
Here is a picture of my 2 big presses on
the heavy bench, with the case spinner/lathe
on the back of the bench. Blue one is a Walnut
Hill and the green is beefed up Ammomaster.
Both are braced so I can lean on them.Bench is
braced to wall supports and benches behind.

You can see the expanders laid out on the press
brace arms, and a whole bunch of shorty dies laid
out, that fit everything from 10ga down to
my 700HE. And variety of large cases and real large
4ga-8ga dies, parts I work with. On the right is a
stack of my 585HE dies in the die boxes.Ed

http://www.gunownerstv.com/ben1.jpg

Now might get real exciting load developement wise,
If we could make brass cases as long as the paper
one on the right. In picture is 3.5" 10ga plastic
case, our 10GA FH brass 4.05" case I made by putting
a 10ga basecup on 50cal Russian brass, and third
a 6" long 10ga bomb disposal case used to shoot
liquid/gel in to bomb packages, I think.
Anyone knows for sure let me know.ED

http://www.gunownerstv.com/10ga6.jpg

Here is picture showing surplus 50 Russian case before
and the 10ga brass case we make using it with
10ga bases pressed and epoxied on and expanding
case out straight, making the 4.050" long
10ga case.Makes a great 10ga FH.
And the case isn't weakened any, by the
process of putting on the rim.It will
stand any pressures any gun could...ED

http://www.gunownerstv.com/10gafhbef.jpg

Hubel458, I have a 12 gauge paper case in my collection that is about 6" long. I was told they were used for turning over the radial aircraft engines to help start them in WWII. Apparently the engines had a receptacle where the shell was inserted and could be fired by the pilot to help turn the engine over when he hit the starter button. I knew it had to be some kind of industrial use.

Thanks for the info. This 10ga one is probably same use.
It is an old paper case. Guy said something about bombs,
so maybe it was used to start the huge radial engines
on WW2 bombers.Ed

We have put 4 different cartridges in the Savage 210
bolt gun. We added various 12ga and .700"
heavy thick barrels.
The first was our 12ga FH long case.
The second was my 700H 3.25" belted case.
Third was the 3.5" 12ga that Bret did, and
fourth is the 700NE that we wanted to see
how it works. It shoots fine, has weighted stock,
and a 27 inch barrel.Has a double thick pad.
I even have cast slugs for 700.
Cases are expensive, ones in picture are
20 bucks each...Ed

http://www.gunownerstv.com/matt700.jpg

Here is picture of my Mossy 695 that has heavy barrel for
the our long 12ga cases, in fact it chambers the 12ga
belted shown in picture ok that I use for testing.
I set chamber to do belted as well as rimmed.

Second picture is some of my 585 Short HE cases, that work
great in regular length actions.We have these in Ruger,
Enfields, Mausers already. I have available supply of
brass for these of about 8-9000. Ed

Getting to some more 4ga/bore work.With barrel and
falling block action locked down fired off some blank
type loads to test the breach and firing pin I set up.
I fired it by hitting the back of firing pin with a rod,
as I now have get hammer and trigger setup. Firing pin
dents primers ok, breach works and headspace is ok.

For loads I have wads to take up space above powder.
Others with same 4ga case in doubles fill case about
1/6 full of Blue Dot (110gr), with 2000gr slug.

I'll use 1600 gr hollowbase slugs, with about 1/3 of a case
of IMR 4759 or 1/2 to 5/8 case of RE17, rest filled
with fiber wads.These are shotgun primer loads and I will be
using THE STRONGER PRIMERS OF KILN CASES at about same
price as BMG primers. And I have BMG primer cases also
that I will test also, once gun is finished in a few weeks.Ed

Fired 4bore with 760 gr light round ball with
fiber wads under it, using 150gr Blue Dot
and shotgun primer case. Just starting loads
for testing operation. Hardly no recoil,
like a heavy, beefed up blank load,
could go much higher with that light
of round ball. Will have pics of the muzzle
blast and the gun shooting from the side,
using heavier slugs in a week or so.
In Owen's 4bore double,that uses same case
size they use max of 110gr of Blue Dot
with 2000 gr slug. Ed

Fired the 4bore with the 760 gr round ball,
which is a hard rubber coated steel ball,
thus the light weight compared to lead,
using 100gr of Blue Dot under 300gr RE17,
total 400gr. Hairy load, with 3500 fps, and
20,000 ft lbs. Used the turned 4bore cases,
with shotgun primers, and with that light
projectile case doesn't need sizing. This is
good beginning bullet weight for early testing.
I am gonna do 1200gr and 1600gr holding the
speeds to give about same energy.
I won't load heavier until I get another
stock like one I have that is full width.
Also those who want 3.5" 20ga brass cases,
Rocky Mtn Cartridge is making them now.ED
