shot this one off the shoulder, pretty mild recoil, not too sharp of a kick
~ 800 grain slug (0.705" wrapped with Teflon tape)
73 grains by weight Triple 7
1 Nitro card & 2 Fiber wads
Magtech brass
made big dent in 1/8 steel, almost penetrated, small rip in middle of dent

In modern gun..Use one less wad, replace with powder, might punch hole through plate.
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.

Ed,
Does your 700 Hubel Express fire a 0.729” Bullet?
I’m making 0.729 jacketed bullets and want to find a test bed or two.
I’ve seen reference to a 729 Jongman. Seems like a rimless 12gaFH.
Looking forward to your response.
-
Our 700 fires .700" bullet.
Easiest way is to get 12ga NEF Ultra with bull barrel,
and lengthen its chamber from 3" to 3.5" and get 3.5" RMC
brass cases, made. That would give them a fair test, 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

A few times on here i have seen people post things about clubs and places that let me know they are in my area i am in Clare county (Harrison) I have heard the name Bob Snapp do not recall if here or not did he go by a different handle here at castboolits?
I read though his obituary and believe i had met him a couple times while i was in high school i had gone with a buddy and his father to a gun shop in Royal Oak attached to a house the gun shop owner being a friend of my Friends father. Reading the second article makes me wonder though unless he stayed in royal oak a couple years after he bought up here i believe it was 1971 or 72 that i was there ?

Ed, if I get a nef 12 ga. ultra slug shotgun bored out for a 3.5" shell, what kind of pressures will this gun hold up to, and what loads would you use? Thanks, and I really have enjoyed reading about your experimenting with the big bores.
-
It will handle the max that 3.5" plastic cases handle, about 15,000 psi,
with slug up to 630 gr use 90gr of 4759 powder or 105gr RE17, use
cards and wads so no airspace.Roll crimp. With light slug 400-450 gr in a sabot
use 5gr more of 4759 or 10gr more RE17, If re17 loads seem mild
go up couple gr at a time. right loads get you 5000 ft lbs ..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..

Hey Ed, it has been 6 yrs now since you came up with those sabots way back in page 29. Since there are none available won't you tell us who has the injection mold so that we could arrange to have more made? Thanks for a reply.

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....
https://www.youtube.com/watch?v=jyab...ature=youtu.be
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......

Thanks AM- I work more now with the big brass cases than shotgun stuff..
HT---I sold the sabot idea/stuff to jmortimer and he has
had a run of the sabots made and is supposed to be selling them.
Hope he hasn't passed away... Ed
-
Ed H, Its great to know you have been working hard, A body in motion stays in motion ! !
JMortimer has been a great friend and its his efforts that I'm back.
May Gods choicest blessings be with him and keep him healthy.
Amen to that.
**--** I have been trying to reach John's mobile but the people who answer told me he does not live here anymore ! ! Please don't call this #.
I remember very well the Sabots were costing Ed far more than he was trying to get his blocked money into them back, there were then not enough wanting to buy. Ed could not even treat his wife to Burgers from the proceeds of those Sabots ! !
All that glitters is not " Gold "

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..
