28GA FH research. Guy on forums suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into
it and did some testing. It is ok as long as you keep bullet
about 400gr as most 54cal barrels are not super alloy.
You got to use the thick heavy ones also, being stronger.
And everyone with 28ga wants slugs and there is no slug loads
from factory, and to reload the heavier bullets we shouldn't use
these barrels or regular 28ga barrels with 600-700 gr slugs.
But there are couple dozen 54cal bullets out there
stocked all over the gunstore shelves, in weights from 300 to
450 gr. There are heavier but for 28GA FH on deer 400gr is
great. I tested the 405 gr copper plated Powerbelt brand, with
velocities from 2300 to 2800 plus fps. That's 6500 ft lbs.
The 54cal slugs load tight in the RMC 3.25" 28ga case fine by
sizing top a little tighter. Bullet obturates to fit .550 bore
as bullet is hitting target straight. A lot of 54cal barrels
go from 530 to 560. 54cal slugs range from .534 to .560"
There are different sizes of 28ga barrels and chokes,
so some where there is lighter 54cal slug that fits..
And with light slugs the pressure limits with the MRC brass
match top muzzle loading pressures, so these barrels will work.
And great thing is the 54cal barrel guys ain't allergic
to making long barrels. I've shot one MRC case 15 times and
still going strong...Ed

A freinds son is doing a gunmakers apprenticship at westley richards in Birmingham, England.

2 years ago a rather rich fella wanted a rifle built with his own custom calibre, the gun makers came up with a .500 Rafiki

the Rafiki part being the chaps surname

1000 rounds were made plus 1 each for every member of staff at the factory

it is a 700 nitro express necked down to a .500 bullet.

the bullet weighs 1000g and was let off some ridiculous amount of powder which i cant remember, when i see him next i will get a picture of the round and exact recipe they used, my only thoughts was that it would hurt a little zeroing this beast.

From memory he paid about 200 grand UK for the project

While evil men cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles

The Rafiki is just about like a rimmed 50 cal BMG.
About like our bmg cases with rims on before we fireform
them out to the 12ga size.

28GA FH testing. 405 gr in 2.75" plastic case
got 1400. Tested the Great Plains 54cal
lubed slug, runs from 2200 to 2700. It is
by Hornady and its front band actually measures
.550" and hollowbase. They hit target straight.
Got a bunch of 415gr hollowbase coming that
are 548" from Dixie Gunworks. Only 26 cents each.
All will work in plastic or long brass
case. I found another .550 bbl and coming, and
it will go on a Mossberg 12ga bolt action
for the second 28GA FH to test.. Ed

Tested the 415 gr hollowbase slugs in 28GA FH long
brass case. These are ones that Dixie Gunworks sell
that they call their Sharps .548" slug. They all run
about .008 bigger than that so they make perfect tight
fit for .550" barrel, and I used a good lube on them
in the grooves. They are a little harder alloy slug than
the Powerbelts or Great Plains The 28ga shellholder
for our Lee, Lyman, Rcbs presses , we use, is from
RCBS for regular metallic press rams. For 28ga dies
Hollywood made some for metallic presses.Also for
sizing for bottom 2/3 of the brass case you can cut
top off of the 500J die.The slower powder loads don't
even have to have the bottom half sized, which
is great for a turned case. If we had drawn brass cases
we could get 11,000 ft lbs, in the Enfield, which we
don't really need for deer. 4-6000 ft lbs is ok ..Ed

Here is picture of a jacketed hollowpoint
12ga slug a fellow is going to make for us.
We hope to have tooling set up this summer
we plan on. Next to it is a 600gr Dixie hardened
slug. First ones he will probably make will
be about 700-750 gr.Ed

The hollow pointed slug above can have a
light plastic/rubber nose for streamlining for
better BC, for 2-300 yard shooting.
In the 87 Win Levergun, smooth barrel,
long barrel, using brass RMC 3" cases,
1 oz Brenneke KO slug to 2700 with 4227
powder. Shotgun primer. I will be getting
some 3.5" RMC brass that he will put a special
longer corner radius in, to allow faster loads
with less case expansion and easier resizing.
Should get same slug to 3000 and resize
easier also. With shotgun primer able to use
4227, and you WON"T have to rework hammer
or firing pin to do big primers.ED

Santa sent me 9 more PROP cases used in little
cannons for bomb disposal. Got 12 now.
In pic is two of our originals on left.
Next 3 are PROP cases resized, and they
match ours we put rims on. Ed

Here is picture of the Enfield bolt,

The huge bolt handle base 3rd rear lug.
Bolt handle needs polishing.This one
will be in the action for the 8GA FH.
The Enfield I have 700H in is like
this also.Ed

THE 8GA FH BELLERED TODAY. It is in Enfield I rigged with
rear locking bolt lugs. 32" barrel, tested 3.3" plastic cases.
Cases are the REM kiln gun cases. With the double cup base.
I shaved base a little so that chamber will fire these as well as
regular 8ga plastic. None of the firing today expanded base cups
at all, so they are real strong cases. Started testing to check
ignition with shotgun primers and to see if cases are any
good. Starting with a 110 gr mouse ball, wad under it, and 150 gr
of Blue Dot, about 5000 fps.. Gun didn't even recoil.Then a
410 gr one at 3000 fps, Then a 770 gr hollowbase slug in a wadcup
up to 2000 so far with 180gr of 7383. Barrel is smoothbore. 832"
bore at the muzzle. Ed

Some 8GA FH testing- using IMR 4759, 770 gr slug,
top load of 140 gr, got 2500 fps......
Over 10,000 ft lbs..Cases extract easy.
The plastic in 8ga case is twice as thick as
in 12ga cases. Tried 4227 and case is too large
diameter for dependable ignition.So it's
old dependable 4759..Ed

Here is picture of Enfield 8GA FH. You can see plastic case
in the port. Box of cases behind, 770 gr and 1050 gr
slugs in front with the 8ga wadcups I use.
Left two slugs are 1050 gr made from 3 oz kiln slugs.
I rounded nose and put in hollow base. Also the
cards and fiber wads used. Slugs are hollowbase, as
it is smooth bore barrel. Ed

In picture of the 8ga bolt action you can see the
ring I put on front of bolt to support large diameter
8ga casehead. It is suported against thrust by the
front lugs, and total bolt thrust is supported by rear
lugs and have taken the heavy loads ok.. Ed

Here is picture on left of the 12ga hollowpoint slug
with plastic tip. Makes it streamlined, good for 300yds.
And still will expand good thin skinned game-deer.
I put tip in with glue gun in few seconds, and
shaped a point on it with trim knife. Ed

I also have two other cartridges with my name
on them that I am promoting. They are my 700HE
and my 585BHE. They both belted straight cases.
Montana Rifle company is coming out with their
big PH action and some guys will be doing my
cases in them.
Info on the 585BHE. It will work in
any gun that handles 505 Gibbs like Enfield, CZ,
Ruger,etc.Mine is in Enfield.On left in picture
is one next to puny Trex. And mine holds 15gr more
powder than that Trex case. 585BHE will do 750
grain from 1800 to 2800 fps in my Enfield.
Anyone interested setting up a gun, contact me
I will furnish reamer and 15 free cases. Cases are
headstamped. When done return reamer to me, for
the next guy. I will keep them sharpened. After a
few guys have guns we all will get together with
others wanting some and get a run of brass made.
These cases are all drawn high pressure brass.
I'd like guys to ask for reamer when gun is going
to be ready to chamber, that way reamers get the
most guns done in shortest time.Ed
