12GA FH--Hairy Shotgun/Rifle--

[MUSIBIKE]

That is a real COOL looking system!

Some interesting shooting with 4bore.

Double 760gr ball load of 1520 gr total, at 2300 fps.

A buck and ball load, 6 45cal lead balls, 133gr each,
and a 760 gr ball on top, 1560 gr total, at 2300 fps.

Both loads 100gr BlueDot under 225gr Re17, In the
turned brass cases, with shotgun primer.Recoil
manageable, and like a big push. The sound isn't
a boom like regular shotguns, but cracks loud
like big bore rifles,at least twice as as loud.Ed

We need a video of the 4 Bore!

I got my 20ga FH 3.5" brass cases from RMC.
The case capacity in water is 234 gr.
It holds 215 gr of dense ball powder to the
base of 490gr 20ga hard lead slugs I have.
These cases use a 209Mag shotgun primer, and
I have mouth ID set up for .620 slugs as the slugs
and sabots I have are that size. These cases will
work good out to 35,000 psi, without extreme
expansion or resizing problems. Load of slow powder
will get 490 gr to 2500 plus at 25-27,000 psi,
6800 ft lbs, using the 30" barrel I'm getting to
put on the FBW Model L falling block.
! also have a case of the 3.5" factory Hastings
SPW, locked on sabot, loaded rounds to use.Ed

Here is pic of the RMC brass 20ga 3.5" with
Hastings 3.5" factory plastic case loads,
and 20ga Hollywood dies. Also slugs, Dixie 490 gr,
Hastings SPW and 900gr jacketed in the one case.

Second pic is the FBW Model L setup that will have
20ga 3.5" chambered barrel in a second one. This 1st
one is in my 585HE.It is falling block in one piece
thumbhole stock, an idea I come up with on my
4bore falling block. Second Model L will be built same
in 3.5" 20ga. Ed

Transition, biggest to a smaller, in
putting falling block actions in one piece stocks.
First one was the 4bore, the big one in
picture and after it was done I got a FBW falling block
and soon figured out I could do the same with it.
It is chambered in my 585HE cartridge.
And it is pictured above with the cases.
I built the 4bore, from blocks of steel.
The FBW is the Model L, and I'm doing second one
in 3.5" 20ga, to use brass and plastic cases.
And maybe later on when I find extra 700 barrel
we'll do my long 700HE in FBW....Ed

[hubel458]

Here is picture of FBW Model L in one piece stock,
compared to a FBW Model S in 2 piece stock.
Both are chambered in my 585HE.
These two plus the Wickcliff 76 and Ruger #1
will easily handle my 585HE with proper
weight and thick pads. These guns have
rimless extractors and my 585HE goes in and
out with least amount of metal removal from
the feed trough, with much more power.
The Model L will have a 3.5" chambered 20ga
barrel to use 3.5" MRC brass cases and
Hastings factory or reloaded plastic cases.Also
I'm working to put a Wickcliff in 1 piece stock.Ed

I just won a rifled 27.5" 12ga blank on Gunbroker.

Oops... I think another project just horned into the queue.

Looks like I need to get with Ed about chambering, and see if he has any more brass to sell.

The Voices are saying "Maadi-Griffin in 12gaFH." And why not?

[hubel458]

You can get 3.5" brass at RMC the cheapest and easiest.
Rob on AR makes the original for more. Here is setup
maybe easier to do also---
Here is picture of a bolt action a fella on Practical
Machinist built for an 8ga. 4 rear bolt lugs.Singleshot.
He used section of 20mm barrel for barrel.. Real nice.
Idea would do for 10 and 12ga also I think.
Has an aimpoint sight. Ed

I haven't looked at Practical Machinist in a while. I'll check it out, and get with Rob.

Looks like I'll have to bore through the thread on Accurate Reloading again, too...
