12GA FH--Hairy Shotgun/Rifle--

[hcpookie]

Ed, thanks for the info! As a matter of fact I am converting my cases to use shotgun primers with the insert, so that is definitely going to limit my powder selection. I don't want to limit my powder choices to something where I need to have duplex loads just for reliable ignition.

I am thinking about loading up some RE-17 rounds for the simple fact that it will be easier for me to buy that powder locally... 1 pound of powder is much more affordable than 7 pounds + hazmat shipping fees. Hard to do all of this on a tight budget!

We have put 4 different cartridges in the Savage 210
bolt guns. We added various 12ga and .700"
heavy thick barrels.
The first was our 12ga FH long case.
The second was my 700H 3.25" belted case.
Third was the 3.5" 12ga that Bret did, and
fourth is the 700NE that we wanted to see
how it works. It shoots fine, has weighted stock,
and a 27 inch barrel.Has a double thick pad.
I even have cast slugs for 700.
Cases are expensive, ones in picture are
20 bucks each...Ed

Here is picture of my Mossy 695 that has heavy barrel for
the our long 12ga cases, in fact it chambers the 12ga
belted shown in picture ok that I use for testing.
I set chamber to do belted as well as rimmed.

Second picture is some of my 585 Short HE cases, that work
great in regular length actions.We have these in Ruger,
Enfields, Mausers already. I have available supply of
brass for these of about 8-9000. Ed

Getting to some more 4ga/bore work.With barrel and
falling block action locked down fired off some blank
type loads to test the breach and firing pin I set up.
I fired it by hitting the back of firing pin with a rod,
as I now have get hammer and trigger setup. Firing pin
dents primers ok, breach works and headspace is ok.

For loads I have wads to take up space above powder.
Others with same 4ga case in doubles fill case about
1/6 full of Blue Dot (110gr), with 2000gr slug.

I'll use 1600 gr hollowbase slugs, with about 1/3 of a case
of IMR 4759 or 1/2 to 5/8 case of RE17, rest filled
with fiber wads.These are shotgun primer loads and I will be
using THE STRONGER PRIMERS OF KILN CASES at about same
price as BMG primers. And I have BMG primer cases also
that I will test also, once gun is finished in a few weeks.Ed

Ed,

I'm getting my reloading setup ready to go and I have a few questions, even after re-reading the entire discussion!


What are your recommendations to taper crimp for all-brass shells? I'm looking at all of my crimping dies and they are all use a collet crimper of some kind. Now, I have several large collets I use with my end mills, and I'm thinking I can figure a way to use them to crimp these large cases. Is there a specific kind of crimp that is needed, or do you think the collet idea will work?


Do you have primer recommendations? I'm planning to use Winchester or Cheddite 209 shotshell primers unless you recommend a different brand?


Recommendations for a wad column? Several times you mention not to have any space in the shell, use cork or filler to take up the space. Do you have any favorite commercial wads you like to use? I'm probably going to start with some 400gr and 600 gr slugs.


Thanks!

Taper crimping works good and is easiest on brass cases.
Rmc thick brass is harder to crimp, and ROB and Rip
have used collets. The Win And Rem primers ok.
Secret is really making sure you have good strong pin strike
and at least .065" pin protrusion.
Using our slower powder loads---
For powder seals I like the BPI BPGS seals one or two and the
BPI flexseal for cushion. get a BPI catalog and there you can
see and get alot of ideas. Yes you don't want any air space
and if more filler is needed above flexseal the cork wads
or fiber wads work.If you use lyman slug in wads cups
they will have a cushion and the BPGS seal fits uder them.
If using saboted slug the flexseal and/or cork under sabot.ED

Fired 4bore with 760 gr light round ball with
fiber wads under it, using 150gr Blue Dot
and shotgun primer case. Just starting loads
for testing operation. Hardly no recoil,
like a heavy, beefed up blank load,
could go much higher with that light
of round ball. Will have pics of the muzzle
blast and the gun shooting from the side,
using heavier slugs in a week or so.
In Owen's 4bore double,that uses same case
size they use max of 110gr of Blue Dot
with 2000 gr slug. Ed

[hubel458]

Fired the 4bore with the 760 gr round ball,
which is a hard rubber coated steel ball,
thus the light weight compared to lead,
using 100gr of Blue Dot under 300gr RE17,
total 400gr. Hairy load, with 3500 fps, and
20,000 ft lbs. Used the turned 4bore cases,
with shotgun primers, and with that light
projectile case doesn't need sizing. This is
good beginning bullet weight for early testing.
I am gonna do 1200gr and 1600gr holding the
speeds to give about same energy.
I won't load heavier until I get another
stock like one I have that is full width.
Also those who want 3.5" 20ga brass cases,
Rocky Mtn Cartridge is making them now.ED

[hubel458]

Tested 4bore with a double ball load of 1250 grains weight,
Used 100gr Blue Dot under 250gr of RE17, with card and
one fiber wad. 2600 fps. Recoil not bad, just brisk.
Used turned brass cases with shotgun primer, and cases
still didn't expand base. just size top..
Running about 23-25,000 psi.
The light ball load in above post
about 16,000 psi.. Ed

That looks sweet! You should snap some vids of firing that monster.

Hey I found more information about that revolver shotgun - reportedly made by Baikal. I cannot find the model on their website:
