12GA Rifle From HELL--

Experimental intermediate size action with the Montana PH, for comparison.

It is an experimental action for our 416 HSM, to do our speed testing with

and get a better action than Cheytac size actions, for bigger case ELR use,

without going all way up to more expensive, huge actions.

It is big long round style action that can take our 416 HSM, almost

1.6" diameter and .800" bolt, with locking lugs nearly as big as most

BMG actions.... ED

 

Here is picture of the bolt from the experimental action,

with our 416 HSM case in it. Note the amount of the

base size of locking lugs, the amount of area on the bolt..





Here is link to guy doing special 585 HE in the EU,

Good pictures............www.585he.cz

We tested intermediate action with a 700HE barrel we had here.

Just temporary to test strength. 1000 gr over 3100..

Action worked fine.. Ed.

 

Here is video of early water barrel test of the

12ga From Hell, from years ago.




Here is picture from that video..





Here is the intermediate size action for 416 HSM with test barrel, .Ed

 

In 416 HSM got a 415 gr long target bullet 3800,

with plain barrel, no brake, on intermediate action,

Now my 416 HE gets same 415gr bullet to 3300.Ed

 

Here is picture of our 416HSM cases with screw in shellholders,

for Ammomaster, etc, and slip in shellholders for regular presses

Also have some for big LEE Classic and Smart Reloader presses..

A 378 WEA MAG in picture for comparison...


Second is stacks of 416 HSM, about a third fireformed

and the rest to be fireformed... So far total about 1700, Ed

 

Bob Snapp, 90, the great Gun Craftsman, of

Clare, Michigan, passed away Jan 28th....

He was an esteemed member of the

American Custom Gunmakers Guild,

Being its president in 1992..He liked

working with Martini Cadet singleshot rifles

.Worked with guys testing armor long time ago.

Maybe the 1st to do 20mm.necked down to 50cal

We lost a great friend,,,Ed

 

.....


It is possible rig up holders for many types setups.,

About shellholder supply for big cases,

RCBS and others make slip in holders for shotgun cases

that can work or reworked for big rimmed rifle cases...

Here are various sizes.......

16ga-- .810" rim,........ 20ga-- .760" rim,....

24ga-- .725" rim,....... 28ga .680" rim....

Ch4d and Buffalo Arms also have these larger shellholders...


We fireform the 416 HSM with 65 gr of medium speed

surplus powder, with rest of case filled with farina

and grits mix, with a play dough plug in the neck.

It is loud, so we shoot it into big container through a barrel size

size hole, so the sound is muffled, so it doesn't deafen us..


It is great getting more companies making 416 caliber bullets,

long target and bore rider bullets. Ed..



....

 

Wonder if a PTRD with 5 ft long barrel is stable enough

for ELR , rebarrel to 416 and use our 416 HSM, 500 gr bullet ....

.Here is up north guy using 585 HE in a PTRD with inserts,

Light load.....Inserts are in the shape of the 14.5mm case....





HERE ia video, 585 Hubel Express and water jugs - slow motion

750 gr with 155gr RE17, just a moderate load.....Ed

 

20mm Vulcan is a big case that works ok, without having

the sides made too thick...They have thinner sides

than smaller cases guys are getting that have the sides

made too thick and won't extract easy or work with high pressures.


Here Barnard P Cheytac bolt that would do for our 416 HSM..Ed..

Got guys doing various 416 HEs..

One just built a 416 HE, just been testing it a few days..

And using 168gr of HBMG 475 gr CEB, tested it, in good

conditions, 2 shots at 1800 yards and was within

a 1/4 of minute accuracy...A few shots at shorter ranges

had same accuracy. Ed..

 

Unsane: noun, def: Way beyond insane.

 

More about our 416 HSM from BMG brass, and
our 416 HE & 460 HE from our 585 HE cases
Got reamers for 375 HE, 416 HE and 416 HSM,....

460 HE & 460 HSM are all spec'd, got HE reamer
soon have HSM reamer...Our HSMs have a Wea type
radius on the shoulder..

The fellow that set up our 416 HE in an ELR rifle
and got 1/4 min accuracy,
They got some game out west over 1400 yds..
.Here is the gun they set up.
Using a K&P 34" barrel on a BAT action.....Ed

 

And have got 460 HSM specs setup, the impetus for that is some
asking about one and new great line of 458 bullets CEB now has.

It will hold more powder than the 416 HSM and will get
a 572 gr as fast as 416 HSM gets a 475gr.....Ed..

 

The guys that did the super accurate 416 HE did another
416 HE that has an 8" longer 42 inch K&P barrel..

Used a Stiller action and same load with 475 gr bullet, as in
first gun and and gained about 200 fps with good accuracy.
3065 fps. Tested 2 groups of 3 and less than 1/2 min moa.

And loads they used are not the highest speed loads
the cartridge is capable of....Here is print with specs for
the 416 HE reamer chamber ....Ed....

 

If anyone is working on one, I have the 3.5" chamber reamer for the rifled 12 gauge barrel, and I'm willing to rent/loan-trade.

 

If anyone asks I'LL let them know..Ed

 

Now working on a sprung recoil absorber filled with tungsten powder.

 

I just wanted to post this; I apologize for being so late to announce the news.

The creator of this thread, Ed Hubel, Hubel458, passed away back in November '21. I stayed in constant contact with Ed over the years ever since the beginning of this thread was started. This was the very thread, created here, that introduced me to Ed so many years ago. I went to contact him on another forum that I would speak to him through and I received a phone call from his son recently, who informed me of his passing. It hit me like a ton of bricks. Here is one of the obituaries I found online: https://www.echovita.com/us/obituaries/mi/farwell/edward-hubel-13637491

Ed was a phenomenal innovator of large bore cartridges. Many of them like this one, the 12 gauge FH, were straight cases, but he was also developing new bottleneck cases as of recent years. In fact one of them that he made me aware of, won a King of 2 Mile event last year. He told me that his neighbor ended up chambering the round and shooting it in one of the matches. There were a few of them he was working on recently and I can't recall which of the three it was that I'm aware of but I believe it was a 375 cal. I know he helped develop the 416 HSM, and if you do a search on that cartridge you'll likely find a photo of it next to a 416 Barrett, seemingly dwarfing the Barrett in size.

As you can see Ed always wanted to put info out there for others to learn from, constantly updating the boards on anything he was learning at the time. He helped me work on two different projects over the years of my own and I can say that he contributed knowledge that went above and beyond knowledge I could obtain seemingly anywhere else but from him. He was very in tune with how certain powders actually performed differently than others and how some had very specific traits that other powders did not. That was one of the things that fascinated me and he would back up what he was saying with data from pressure testing sessions that he would show me. I was then able to replicate the results in my own testing, and again, some of the knowledge he passed on just continued to fascinate me.

I could go on for hours talking about stuff for which Ed was the man to speak to about, but ultimately I just wanted to let others know that we lost another one of the greats.

Thank you Ed for all that you have done for the sport, and you truly will be missed.

-Matt
