Another couple months maybe 4 bore/ga will fire.Just have a
chunk of shaft on front to simulate barrel to
get a stock fit. Got to profile barrel, thread barrel,
fit in hammer,trigger, couple bottom bolts into action,
design and mount extractor.. some springs, firing pin, etc.
May change/lengthen fulcrum on lever so it doesn't have to
move so far. Lever is held closed by little feramic magnet
in grip. Checking on different shapes for lever. When breach is
lowered the lever stays open due to weight of breach
block. Block moves smooth, no rattling around.
Guys-,I need some Vulcan 50cal V-50 thumbhole laminated stocks.
If there are any used extra ones around let me know.
This way of doing a FB in one piece thumbhole stock will work
for 12GA FH with an action about a 1/4" narrower.ED

Here is picture of 4bore/ga action with lever open and
breach down.You see bottom of breach block.The action
and barrel will be held in stock with 2 bolts into bottom
of action one bolt in barrel ahead of action and a recoil
barrel ring in front end of stock. Didn't have to add
any recoil lugs, as the wide back of the action is
the recoil lug. This is now called the Hubel Falling
Block Action. Second picture is of the 4bore cases
and 2000gr slugs, with 20mm case I make 4bore/ga cases
from and the 30-06 for comparison.Ed

Wow thats raw power! Looking back at "Grandpa's first shot" you can see the table top cave in from the force.
I would hate to be the bad guy crawling through his window lol.

Here is picture of the 12ga wad column using two
BPI BPGS seals, Flexseal,cork, and sabot. Bret in
MN has, in a long heavy rifled barreled Savage
like mine, gotten 28-3000 fps with a 500 gr XTP bullet
in the sabot with a 3.5" plastic case. And it extracts
ok with the Savage bolt action extractor.
He is using slow shotgun powder, Alliant Steel.I can't
get that high in my NEF 12GA FH and make the
extractor work with the Alliant Steel powder loads.
The NEF handles pressures fine, just doesn't extract
like a bolt action Savage 210. Using RE17 without cork,
I get 28-2900, with max of much slower RE17 with 420gr
slug in the sabot, in NEF The case shown was fired with the
RE17 load like that....Ed

Here is picture of NEF I've set up with my
700H 3.25" belted case to show the versatility
of NEFs and my 700. The 700 cal barrel monoblocked
like I did the 585HE. I put monblocked barrel on
the same SB2 frame that I have my 12GA FH on as
it has the beefed up firing pin for big primers
use in our 12GA FH case and in my 700H case.

Other projects coming.I found a heavy 16ga barrel
to monoblock in one to test the 16GA FH cartridge
I made. It is the 3.5" brass case mentioned
earlier in the thread.

Also a bunch of us are going to take 500 S&W
NEFs and put my 499 HE case in them, with just a
chamber job. It is a case that will get the zip
in 500gr slugs. NEFs are great guns to experiment
with and along with reasonable costs, we don't
have to worry about case length. Ed

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,
and I'll use a big ammomaster press for them..Ed
