12GA FH Slug Tester --

[xfoxofshogo]

cool ya the 98k i have still have 8mm and 30-06 barrels on them where can i buy a barrel that will handle this or how do you go about geting one i like it to look like the old octon barrel im just gussing this is kind like JT 700*** ??

[hubel458]

You can get 12ga heavy rifled barrels at Pacnor. To use Mauser
for 12ga shotgun you must do a conversion on one or buy one already
done. a GEHA. The conversion is replacing the front of the bolt.
Milling out the front reciever, losing the front lug seats,
as it won't lock in frony anymore.getting it head spaced on the
safety lug.And other changes. One this is done it can't be used
for rifle cartridges. The *** is just a shorter little brother to
my 700 HEs, but I don't put them in mausers as the front locking
is gone and you can't add enough rear locking lugs to make up
the difference, Like I do with the bigger Enfield.Ed.

[xfoxofshogo]

will a single shot brake open shotgun work for this ?? if i make a barrel to fit it i just pick one up i was going to ues for bp but barrel bent lol

[hubel458]

Here are a couple high speed, stop frame photos, showing how well
and even these sabots we want to get made, open up.
The petals being thinner with 58 cal bullets or slugs, opens easy.
The slots between petals, going into the base aids even opening.
We know a couple retailers that are interested in selling these
style of sabots, if they round up the money to get the
aquipment setup. Shooting supply companies are down some
due the economy.





Third is the 585 HE project, using a Savage 110-112 bolt action.
Shown with barrel threaded and screwing action on.
And the action is long enough to make a single stack mag, if we
want, that would feed, with a little work, our 585 HE long case.



4th & 5th; pictures are of a old time 20 gauge, double slug and shot
gun that was priced little less than the big name English ones.
It is a Husqvarna double. Nice gun, we'd really have fun with modern
20ga slug shooting using this ..Ed

[hubel458]

Some info we have found out about the operation of discarding sabots.
In first picture you see thin white line between the strong powder
and the sabot. It is the white fiber cushion wad pressed flat. It is
shown on the left in second picture. In the picture of it compressed
you see it is pushing squarely on the sabot. This is most important
wheh the sabot and slug exit barrel to get the slug started as
straight as possible for accuracy.

Other types of plastic cushions aid in sealing and help get best
velocities but the rolls and legs in them can allow them to side shift
which can affect how straight the sabot is on exit, thus causing the
slug to deviate. The gray sabots we tried had cushion on the bottom
of them and inspecting them after firing you could see they were pushed
sideway some of the time. That is why we are trying to get tight
fitting simple sabots built and recommend using heavy plastic seals
with fiber wads to have least deviation and best accuracy.







Third picture is our steel block we are using for 2bore
with breach hole we got EDM'd into it.



Fourth picture is an old time Kynoch round called the
"Lethal" and the "destructor".




Fith picture is a H&H underlever double 8bore.
Nice beautifal old gun.Ed

[hubel458]

I think we found good overall sabot design that will
be the easiest to get made, easiest to get seals
and whatever wads needed... Keeping design simple.
It is same simple design as the ones pictured above
but with slightly thicker base.It is fairly compact
for more room for our slow powder loads, and when
using slower powders, we don't need as much cushioning
which makes the room for the powder. Larger charges
of slower powder, better velocity with less case
expansion, and more reloads possible.

We hadn't tested soft lead 58cal slugs in 12ga sabots
for penetration until now.. They did very well,
two different 440 gr ones, going though 4 inch dried
timber, pushing out some wood on the back.
Shows they are just starting to expand.Should do great
for deer and hogs. Going 2200 in long barrel NEF.
Have pictures later. A 58cal slug at good speed is
nothing to look down on. Many African hunters liked
that caliber in their 577 doubles for big game.
Slugs can be loaded faster, cast heavier,
and cast harder for any need.And compared to other
way of getting slugs out of a shotgun, once
we have good fullbore sabots, we save on needing
bullet lube, gas checks, cheaper to get, no barrel
leading, much better BC in the same weight of slugs
compared to short fullbore ones....


Here are pictures of molds that can make cast
58cal slugs for the 12ga sabot we are working
on.There are many makers and brands and styles
of molds and weights available.






Here is picture of a 10ga wadcup with a 730gr hollowbase
lead slug in on the left .In my heavy barrel 10ga smoothbore
I got 6" group at 50 yds. If we made hollow in the base
bigger it would be more accurate in smooth barrel.
The slug is .69cal one,measures .686"(from Lymam mold
like in picture), that Dixie Gunworks has. I bumped up the
diameter about .015" --wadcup is BPI VP100.




Here is picture of a nice 8ga double a fellow has.
Great looking gun..Ed

Mr. Hubel,

Have you considered Alliant 4000-mr for your experiments? A well respected individual over at Weatherbynation says this:

”In burn rate it ranks between Re22 and Re25. If your mind runs on IMR, think of it as being a little like IMR7828.”

Others have called it pretty similar to RE17. Either way, is on sale at Cabelas for $15 for a one pound can. Might be just the ticket as it is the slowest of the newer Alliant magnum rifle powers.

[hubel458]

Yes It works for my 585HE and 700HE
and for the 12ga FH long brass case with BMG primers.
It is ball powder about like W780 ball in speed.Ed

[jkpq45]

Mr. Hubel,

I found an H&R "Long Range Sportsman" in 10 ga:



At 36" long, sounds like plenty of length to get some slow-burning powder going. Any idea if it compares to your NEF (or if that frame could be rebarreled by H&R to 12 ga rifled, or 500S&W for one of your wildcats?)

Sorry--the NEF vs. H&R line is pretty blurry to me.

Thanks,
jkpq45

[hubel458]

That gun looks like the older model 176. Not the newer models.
The 10ga you want is the newer NEF SB2 frame with heavier
barrels or bull barrels. The SB2 is same newer alloy, heat treated
frame that the 12ga UltraSlug bull barrel is on.
The SB2 frame will not be flamed like the one picture seems to look..
In SB2 10 ga you can get 27 and 32 inch barrels solid choke,
and 24" and 32" bull barrels with screw in chokes.
You have to check serial numbers. to be sure.Ed

[hubel458]

Working more with 58cal lead slugs in 12ga sabot we want
to get built. We shot a few for checking penetration,
with 440gr slugs at 2200 plus fps. Shooting into popple.
In picture the 6x6 on the left penetrated by harder lead
alloy slug, with slug showing very little expansion on
exit from the 6x6, On the right, soft pure lead slug through
a 4x6 starting to show expansion on exit. These slugs can be
gotten or cast your own to about any hardess needed.
They can even be heat treated to be as hard as jacketed.
I have rounded up 9 different ones very easy, shown in
2nd picture and there are more. Ones in picture range
from 400gr to 530 gr. There are molds to make them
down to 350 gr and less.





Here is picture, on left of Accutip sabot we been taking out
of loaded rounds and testing 58cal lead slugs with,
and right a hard plastic sabot model, made by reaming out
one and cutting slot or groove all the way down to see
how slugs fit and how it looks, and how
it compares to the Accutip and other sabots we have
here from WIN, REM, FED, Hornady.



In picture is a really neat, very strong, 10ga Beretta style
gun we got. Its barrel is heavier at the muzzle than most
all 10 gauges we've seen except the NEF with bull barrel.
Made by Pedretti, has top lever to open, instead bottom
lever like Beretta or the Investarm 20ga we showed above.
Going to make into switch barrel for 10ga and monoblock one
in 585HE later. Have 2 barrels for it. Has nice big pad we put
on it and it is weighted to 12 lbs in 10ga..



Now for some internal ballistics comparisons.There is formula
for figuring appoximate Average Barrel Pressure,

You take Muzzle Energy times 12......and divide it by

the BORE Area in sq in, times the length of the barrel in inches.

Examples- you have a 458 WIN, my 585HE and 12ga 3.5"--
all at 5000 Ft Lbs of energy which for 458 be standard load.
The 585HE in this mode would be burning close to charcoal.
The 12ga 3.5 would be 440gr slug in sabot at 2200 plus.

The 458 Ave Barrel Pressure is about 16,000 psi.
The 585HE Ave Barrel Pressure is about 8,000 psi.
The 3.5 12ga Ave Barrel Pressure about 5,200 psi.

The purpose of this-- To show the possibilites of big bores.
Ok you can't go much higher with 458WIN, about 80gr of powder

But 585HE you can get way over 10,000 ft lbs,with 180gr powder
it holds running at 458WIN Ave Barrel pressure.

AND 12ga and 3.5" brass case in Savage 210, slow powder loads,
heavy barrel, you can get over 10,000 ft lb. with 180gr powder
at much less than 458Win Ave Barrel Pressure.
Possibilities are really great fun. Ed

[hubel458]

Some 12ga sabot progress. Here is pic, 2 of our sabot model,
in front, shown with Accutip sabot behind. They are all holding
58cal slugs, showing how tight they fit and conform
to the inside of the sabot petals. A decent fit is a help
for better accuracy. Hope they get built for us this summer.
We are working on it.




Second picture is from our man in this forum, put 58cal cast slugs in a
thinwall 20ga shotcup and shot this at 50 yds. This shows the
great possibilities with 58cal slugs, and should even do better
in the 12ga sabot like the above we like. I've heard about BP
guys who got into 58cal that they get good accuracy.




Here is picture of some the grey bls sabots showing the way
they have got bent and beat up, and shows what I and many
others have found; that plastic cushions can bend and twist
and shift, affecting the slug on leaving the barrel, affecting
the accuracy.




On a future work, I'm doing a Greener Martini in my 585HE long
case, Here is picture of a parts action with a stock idea
I'm experimenting with. Might use this or regular pistol grip.

[hubel458]

Back after losing time to a lightning fried computer.

Test in 3.5" plastic using a few accutip 12ga sabots out of factory loads.
The 12ga accutip sabot, hard cast 440gr 58cal minie slug in
36" rifled NEF at 2200, and it went through 12 inches of wood like
butter. The hole out showed it was starting to expand a little.

Test of softer lead 500gr 58cal Minie with deeper hollowbase in accutip
in smooth cylinder bore barrel at 2000, and 3 shots in 3" at 30 yds.
This was a Lyman 575213 new style minie slug
More experimenting can make these work fair in smooth barrels.
For best accuracy use a blunt nose heavier 58cal 600gr slug with
deepest hollow in the base. The blunt nose would be more front end
heavy and a little more accurate from smooth bore..
Lee and Lyman have molds like that.Others selling slugs also.

I mentioned before about seals/wads must be stable and not crush
down off center, or it might affect accuracy. Here is picture of
the one piece seal and wad Federal uses in their sabot loads.
Notice it doesn't have a lot of space in the cushion part that would
allow it to tip or go off center.



Here is picture of some 10ga work using expanded 69cal minie and
700cal bullets in 10ga wadcup. 69cal hollowbase fairly accurate to
50yds in heavy barrel smoothbore.



Here is picture of the Savage 110 done in my 585HE. Hollow butt of the
stock is weighted, gun handles nice.Ed

[Carryacolt]

Good morning Ed,

In your post #512, you had a pic showing the sabot you have been working to get molded. Is the project still moving along as you had hoped and if so, as many of us here are following with keen interest, can you give us all an update please?

Also, in an earlier post you mentioned that once the sabot had been finalized, it would only be a matter of changing the dimensions to make a 20ga sabot. Is that anywhere in the plan at this time? Would the boolit used still be the 58cal or would it change to something smaller like the 50cal or ???

Thanks for all the work, time, and $$ you have put into this. You, and a select few, are the true pioneers and all the rest of us are benefactors. We all say "thanks".

[hubel458]

The sabot project should get us sabots by the end of summer.
We plan on having one later for 20ga, but they got to make
a huge bunch of 12s to afford to retool for 20s. Might take over a year.
I don't know for sure in this economy. A 20 guage may use
.458 cal slugs.

Guy using scoped NEF Ultra 12ga, 24 inch
barrel, shot hard cast, 400 gr 58cal Lyman Minie
in Accutip sabot at 75 yds. Hit small paper plate
5 for 5. Going 2000fps.

Speaking of 585HE above. We have two in falling blocks,
10 bolt guns,5 break actions, and other types.
A fun cartridge, and now that we are working with
58cal slugs in 12ga sabots, 58 cal is where it is at..
And now we are getting a run of 585HE cases made.
Bertram getting ready to make the last die;
done later this month and will be doing cases then.
Cases are 3 bucks each, bulk shipping included.
He usually charges 5 or more for wildcats, but as
I'm furnishing final sizing die, and he will ship
by bulk freight saving him handling, and he had
a couple tools already to use, he said $3 each, a
real good deal..

He will ship whole bulk order to me.
I will pass them on to everyone buying in first run.
I and the boy will get a bunch also, to load for others,
to fill orders, and collectors. Get 100 for 300 bucks,
or be a 500 guy buying a 167 cases for 500 bucks.
I'm having guys just make out MO to Bertram Bullets
and get it to me and I send them on to him.
I'll keep track of who gets what and ship cases to
the guys helping with first run, no shipping charge.
Want to make the run as big as possible. Got
money ready to go for over 700.
Like to get 3-4 times as much if possible.Ed

[hubel458]

Some more experimenting with the Accutip sabots, Designed a
two ball load using .577" cast lead balls. Bottom ball flattened a
little in vise with the flats up and down in sabot.
Used a fold crimp, 3.5" once fired REM case in NEF, long rifled
barrel.....Fold crimp goes down on the top ball...Round
balls 285gr each, going about 1900 hit within 2 inches at 30 yds.

Those 58 cal inside Accutip sabots are really versatile.
Tested 3 shots with 58cal Buffalo hollowpoint, hollowbase, lead,
muzzleloading slugs, 2" at 30yds. All loads with plastic OP
wad and white felt cushion under sabot.

Experimenting with an Enfield, had one set up with my 700HE 3.25,
and just did one in my longer 700HE. Did little longer port and
added little more weight.First picture. 2nd picture is a neat 3 barrel
16ga, which if I had it,deepen chamber, I'd have a neat 16ga FH....Ed





PS---We are gaining on getting the big run of brass made for our 585HE.
He is finishing the tooling and soon be producing. We want make the run
as big as possible so everyone is welcome to help. You in US get in on
first order, cases are $3 each.Those in the US he'll send whole order to
me bulk freight, a big savings, and I'll get them to the parties involved,
no charge for helping out on first run.The $3 cost is a great bargain
compared to other big bore cases and if you buy 150 or so you've saved
enough, over the cost of others to buy a barrel to make 585HE gun with.
My contact--- gunowner at journey.com

For those in Australia,Canada,South Africa,UK, and other countries
send pmt to Bertram and he'll send cases to you individually when done.
Right nowe can't afford export costs to send cases back out of US.

Here is picture of the two ball sabot load, using two
58cal balls in a 12ga Accutip style sabot.



Hoping we will have sabot like above for reloading soon,
in volumn so we can load and test a bunch of these 58cal
bullets and slugs. There are soft cast, hard cast, and
the heavier jacketed. These all work in my 585HE also.
The 440gr hollowbase ones loose in the big box on left
measure in at .585" and work great in my 585HE cases.



Part of my 585HEs are smooth barrels guns
just for testing the different style guns, and different loads.
In the one smooth barreled one I have on BBK action, shooting
my 585HE with 440 gr hollowbased Minie slug, we were hitting
8 inch paper plate with them going about 2700 at 30yds.
Hollowbased they act like shotguh slug at short rahges.

Will be neat deal to shoot them in 12ga accutip style sabots in
rifled 12 gauges and the smoothbore 585HEs with $30 barrels.
Here is picture of Pedretti(Beretta style) that came as 10ga. I
have monoblocked in 585 barrel. In picture there is 585HE case
partly out of chamber. I have extra fairly heavy 10ga barrel
also and changes in 2 minutes. And that monoblock break
action locks up like a bank vault.Real strong.





And an ultimate big bore from history.ED

[hubel458]

We hope a company will be making our modeled 12ga sabots
soon, this fall, to deliver to reloaders and suppliers..
We also got first part of funds collected for the initial big run
for our 585HE long cases being made. Sending in bunch
this week, and need more to make run bigger For more info
if your interested contact me.

We, others, and 'VdoMemorie' on the Cast Bullet forums
and Shotgun World are experimenting with 58cal Minie slugs and
58cal round balls in 20ga wadcups, and find it is away to slug
load your 20ga economically. You can use 20ga Commander wad and
also shorter "sporting 20 short" wad from BPI. I cut bottom off of
commander and use felt wads and 20ga obturator seal with .575"
470gr minie slug and got 4" group at 30 yds, with smooth barrel.
That is with heavy thick,smooth barrel I put in CBC below.

Here is picture of the CBC break action that I mono-blocked in smooth
super heavy, thick 20ga barrel..30" long, chambered for 3.5" cases.
Works great with 3.5" plastic or brass cases.



Here is picture of the 1887 WIn with my 585HE in it. I put in a
heavy barrel and different kind of extractor Barrel is 28"..
I like putting my 585HE in all the old style of guns, just
to show all the uses the case has.



I found supply of super long bmg cases to make my 700HE Long cases.
It is 4.27" long and holds over 370 gr ball powder, 1000gr at 3400 plus.
I have it in my Vulcan BMG bolt action and I just got one done in
a MRC PH bolt gun, in picture below...Ed

[OnHoPr]

Hubel, it looks like your keeping up with your very interesting hobby. I know your probably getting one of those cannons ready for dangerous 4pt hunting in Livingston county. I thought about getting up in that area for a little squirrel hunting. I wonder if that would be considered dangerous game. Your hobby as Artie Johnson would say "Very Interesting".

[hubel458]

I found pics of a factory 12ga over under that
has bottom barrel rifled, top one smooth with
chokes. Will have pics few days. Also pics of
585HE case samples from the first run
of my 585HE cases, Bertram is doing.ED
