One other thought gentlemen: Once (if) we have our 12 gauge double chokes rifled out, we're going to need the services of someone cabpable of regulating the point of impact. Or are we planning on using sights for one barrel, and kentucky windage for the second barrel?

Of course, we might install sights on EACH barrel, as is done with some double rifles - I believe the Kodiac BP double is so equipped.

I'm currently only working with single barrel as it is all I have to play with but if the slow twist rifled choke tube works out (and is affordable) I have considered double barrel too. If the tubes are slightly (and I do mean slightly by only a few thou) eccentric with a locking collar so they could be rotated to change point of impact for each barrel then they should be "tunable".

With a tapered lead in to the choke tube it should make little if any difference to ball or slug and a slow twist should not be a problem for a hardened ball or square slug since it has been proven in the Paradox guns.

True enough, there isn't much room to play with a double due to thin barrels but I think it could be done. Maybe it would have to be shims or thin sleeves or even machining the locking face to allow more rotation to tune but I am pretty sure it could be done.

The outfit I wrote to is Pacific Rifle: http://www.pacificrifle.com/spc.htm

I haven't had a response yet.

There is also October Country who also do 12 ga. rifled ML with 1:104 twist: http://www.octobercountry.com/rifles.php

I haven't tried them yet.

I would guess that a thick walled barrel blank could be rifled full length then cut to choke tube lengths and machined from there. I have a lathe so not a problem for me to do that.

For single barrel I would go the Cutts Compensator style but doubles would have to be thin screw in choke tubes.

I let you know if and when I get a response.

I received a reply from THE GUN WORKS and they cannot help with barrel rifling..

I am at a loss as to why it's so hard to get a simple rifling job done on a slow twist choke? I know there are people that can do it! And..It's not that complicated. My good friend, Gregg Sappington, has been putting together custom rifled slug guns well before the present sabot fad. He has done some posting on the Slug Shooting forum of Shotgun Wolrld....but that forum is controlled by a poster that pushes the extra high doller Tar Hunt guns in Shot-Gun-Only states When anyone goes there with some other idea....thay get talked down to like they are Dopes!.
On the otherhand, Ole' Dixe (me and the Dixie forum) caters to the everyday hunter. That is why I really like this Cast Boolit group indeed. It seems like this group just enjoys what they are doing and this forum is very informative indeed!As I said before, I don't want the fellows here to think I am just pushing Dixie products. Rather, I am sold on well designed cast bullets and like to discuss their designs.

Longbow... I have written to OCTOBERCOUNTRY.com... I will post result.

Well I can see if and when we can get some rifling work done we better sign that feller to a contract ! He is gonna be a KEEPER !

It would seem to me that rifling. bore/groove, and twist data is historical and could be found. Then a smith to execute the barrel, and one to fit it to a simple platform like a break open shotgun. Then cartridge work, then single barrel repeaters, then the double. Eh? Are fully rifled barrel dimensions not already well known ? BvT

[yondering]

Just a thought here, but it could be that it's hard to find a rifler because they don't want to try rifling a (relatively) thin wall barrel or choke. Watching my local custom barrel maker (Benchmark Barrels), he cuts the rifling when the barrel is still a 1" round bar (this is for rifle calibers). The barrel profile is not cut until all rifling is complete.
A thin wall of a shotgun barrel or choke may resist the rifling cutter, and distort and maybe cause chatter?

Octobercountry replied they cannot help with this project. They did suggest calling "JOE" at GUNWOKS. I also tried to contact Mossberg... but I could not find any Email/WeB contact menas . They only have a phone # which is not a good idea from here.
Above YONDERING suggested maybe it is a "production problem". Maybe it is more feasable to hunt a 1-100 (or so) barrel linner and "line" a cylinder bore barrel ??

[longbow]

I still have no response from Pacific Rifle so will try another BP barrel maker or two.

If anyone comes across a barrel liner who has slow twist liners in 12 Gauge post that info... may just be simpler to reline a cylinder barrel.
