I finally got my 12 bore barrel from ER shaw yesterday ( It looks better than I thought). I plan to chamber it for the longest version of the 12GA FH I can get to chamber in a Greener shotgun action and see what it will do. It will be limited to about 35KPSI and I'll proof it first. Should be fast and fun!-Rob

Will this be a single shot hammer gun?

Will it be for that super long Hubel 12 gauge round?

What weight bullet will it shoot?

He is putting it in a Greener-Martini single shot.He will have to shorten the long version
of the case that he and I made, by putting rim on
BMG brass.This case is his invention, I only helped figure out how to get a rim on it.

Rob-What is the outside diameter of the breech and muzzle of that barrel from Shaw?I assume
you are going with original barrel thread size.
What gun weight are you planning on?Ed.

Straight from the ER Shaw web-page:

"We will supply contoured blanks, 25-1/2 inches long (will clean up at 24 inches). The breech end is cylindrical for four inches at 1.225, then straight-tapers to .925 at the muzzle. Rifling is 1-28 RH; nominal bore and groove diameters are .719 and .729, respectively. Steel is AISI-4140 with Rockwells 24-28 on the “C” scale."

The pair they exported to me last year were straight 1.225 dia full length.

Whenever I suggested/recommended ER Shaw barrels on this forum in the past, I was howled down and Shaw barrels were summarily sh!t-canned by all other posters. This did not fit with the quality tubes I recieved from them. Glad someone else has at least taken the trouble to have a look, rather than just shooting from the hip!

I have a keen interest in your results, Rob, as the tubes I acquired are not yet profiled or tinned into anything interesting! Decisions, decisions!
Keep us posted.

Marrakai--Yours being straight barrels is a smart thing you have done.I was one who worried on other
posts that contoured barrels might split out
beyond the heavy breech, as this case is being loaded to rifle pressures.If Rob is successful are you going to use a Greener or
build one one a double barrel action?I will spend
this winter getting a thickwall Greener built
from scratch, to take full length case, and use a real heavy barrel.I got some sample 12 ga 750
gr hollow base bullets from John at Bridger Bullets(fritz454).He does great work.Here is
picture of one in 12GA FH long case, a bullet standing, and one showing hollow base..Ed

Ed, this is where I'm coming from.

I have always wanted a 12-bore Paradox, a couple of my mates have originals but I have not had the ready cash when limited opportunities presented themselves. The guns have now become quite expensive, so I decided to make my own. I picked up a 1 1/4 oz Wm Griffiths boxlock with blown tubes. My original idea was to buy the Shaw barrels and ream out all the rifling except for 2 inches at the muzzles, profile them down, and sleeve into the Griffiths. I may still do this.

When the barrels arrived, however, I realised that 24 inches is a bit too short for a 'pukka' Paradox, and they were nice and heavy, so I decided they would be better used to build a 12-bore double rifle. Consequently I have advertised for a pommie 10-bore SxS shotgun with stuffed bores, to use for the sleeving job. Nothing yet.

Back to the Paradox project, I acquired a pair of Remington rifled chokes, and went looking for a used pair of 870 barrels threaded for the chokes, at about the time my Prime Minister declared all pump and auto shotguns and their components to be prohibited items in Australia. I am still trying to find a couple at 26 or 28 inches, and if successful they will be sleeved into the Griffiths boxlock with the rifled chokes fixed in permanently and faced-off neat.

The Greener 'GP' was to be used to check how well the rifled Rem-chokes worked (and to give me a functional 12-bore single-shot rifle), but I am flat out finding ANY barrels threaded for Rem-choke, let alone a third one for the GP!

If I was in the US, all this would be as easy as a phone-call, but even importing barrels into Australia in this post-9/11 world is a difficult and lengthy process.

WHEN I get enough of these problems solved to begin construction of either the 12-bore double rifle or the paradox, I will post results here. Meanwhile, I really enjoy hearing about your successes, it can only spur me on!

My barrels are also 1.225 straight. The Bores LOOK really good to my eyes. I slugged it yesterday with some soft lead and could not feel any tight or loose spots. For $125 it has already exceeded my expectations. I'm gonna just use a boring bar and chamber it for a 3 1/2 inch case. It will be easy to then fit it to the Greener.-Rob

Ron,

What say we set up a deal between us so I can get some 12gafh-short cases from you. I have the Encore ready to test and I am playing with a fixed gun idea with a sliding breach to try to push things. I also need to get with John(fritz454) and get some of his turned solids. As always my attempt here is for something in this range anyway, the full monty 12gafh is beyond my interests.

Brian

Pyronecro-John has some turned brass bullets available and I will make some cases as soon as I get power back to my Lathe. Maybe next week.-Rob

Rob-What weight bullets did you get from John
at Bridger.Are they solid or hollow base like mine
that I plan to use in a smooth barrel(750 gr).Pyro is your barrel rifled or smooth?
You will also like those cases built by Rob
on BMG brass. Tremendously strong..Ed.

My barrel is smooth with a rifled choke and one fully rifled. But only really useable for lower pressures. I have been trying to figure out how to put a dolls head on a encore, but really unsure if it needs it. I am hoping to accomplish my aims at 25-35,000 psi.

Brian

A dolls head would be no problem. just copy the dimensions of one off of an old english double rifle and have somebody sinker EDM a copy into the encore frame. You could Tig weld a top strap with a dolls head onto the barrel..-Rob

HEY!!!
i've shot that design of bullet, minus the hollow base...

John, i am running out of .510bullets... it's a damn shame that I can shanghi woodleigh softs cheaper than I can get barnes..

when are you open for biz?

Hello to eveyone.
I've enjoyed reading the posts about the 12 bore rifles very much. I was thinking about building a 12 bore muzzleloading rifle a couple of years ago but instead discovered the H&R line of single shot rifled slug guns. I bought a Ultra Slug in 12 ga. and it has become one of my favorite guns. I shoot it mainly with black powder and roundballs for "plinking" and use a bullet cast from a modified Lyman sabot slug mould for hunting. The Lyman bullet is designed to go inside a shot cup and is actually sub-bore, but I couldn't get them to shoot in my gun so the mould was opened up to cast a bullet .740 out of 20:1 lead/tin in order to use it without the shotcup. The new bullet weighs 595 grains and is very accurate. I usually fill the hollow base of the bullet with bullet lube and it seems to shoot more accurately thus loaded.
I buy new, primed Fiocci 3" hulls for loading this gun and bought a roll crimper from Ballistic products. I was amazed at how easy the roll crimper was to use and the crimps look like factory! It makes for a very impressive looking cartridge indeed.
Both the round ball (600 grain) and the slug will cut one ragged hole at 50 yards. My light load is the roundball with 120 grains of WANO powder. I use an over powder wad and a filler wad (from Ballistic Products) under the bullet. I use a pinch of 2/3 beeswax 1/3 Crisco for lube. This load gives 1100 fps and I even killed a deer with it last year.
Velocity wise, the top load has been a 200 grain equivilant load of Pyrodex P (slightly compressed) sans wadding with the hollow base of the bullet filled with the above lube. It gives 1600 fps and shoots about an inch at 50 yards.
I couldn't be more pleased with my gun and would recomend them to anyone who wants to have a really big bore rifle at a very reasonable cost.
