I know this idea has been flogged to death but..after reading a bunch of the posts on this I still couldn't find a definative anwer to which brand actions are strong enough and what would be the max pressure you could have.
Would a Stoeger coachgun action be strong enough to contain 2 rounds of .357 at the same time for example?Where can you buy barrel blanks here in Canada?
 
the ones that i've seen were made on Russian Baikal actions in 45 -70. its my understanding that you require an action that is machined not cast. there are used baikals on the tradeexcanada site at the top of the page. if you make one please post the pictures.
 
rifle from shotgun

At one time, there was an aftermarket 375 H&H conversion double barrel assembly available for the Ruger Red Label over and under shotgun. So the Ruger Red Label is strong enough. I believe the supplier was Bruce Steacy who makes some excellent and pricey double rifles. He no longer makes the conversion assembly so perhaps there was some problem but ???.
 
Go to Nitroexpress site - Building Double Rifles & Gunsmithing - find building a double .303 by Ron Vella page #2 I think. And a lot more info. to answer your question(s). --- John303.
 
Trick would be finding the barrels. Double rifles are expensive because it isn't easy getting the barrels to shoot in the same place. Just a blank won't help much.
 
I have seen Vella's rifles, and they are outstanding.
There is a reference book on the topic.
A quality double is needed for the basis of the conversion.
Obviously the barrels will have to be turned to the required dimensions.
Generally, the breech sections of the original barrels are used to make a monoblock into which the new barrels are fitted.
Regulation is going to take time and patience.
The shotgun action must be appropriate for the cartridge chosen. Some rounds produce a lot more backthrust than others.
 
I have 30-30 built on a Browning BSS 20 ga. I have shot it lots and it works and shoots great.The book you need is written by Ellis Brown, Building double Rifles on Shotgun Frames. I did not build mine I purchased it along with the original 20 ga shotgun barrels as a set.
 
Hi there!

Please let me know how your project turns out. I've been thinking about a similar project for a number of years. I like to have a.22 or 9mm in one barrel of my 12 Gauge SxS, so that it can be a close dispatch round.

However, I have been trying to get a pair of adapters from MCA:

That would be a lot easier than trying to build barrel...

Thanks,

w.w.w.
 
The trick is to find a shotgun with a third locking lug (crossbolt lock), often called a "greener-type lock", based on the famous Greener design. If you can find a good quality 12 gauge with that lug, you can build off it.

Essentially you chop the shotgun barrels off about 3.5"-4.5" from the breech, and use that as a monoblock. You fine female-thread that block, and then fine male-thread the two barrels. You apply solder to the male threads, then thread in the barrels. You then heat up the monoblock until the solder runs again. Between the fine threads and silver solder, the barrels won't go anywhere.

The next steps are fitting the extractor, and then regulating the barrels (a bit of a dark art).

You need a lathe, machining experience, soldering/tig welding experience, and a lot of test ammo.

A note on ammo: you regulate the barrels based on ONE load. One bullet weight, and one specific powder charge. Or else it's impossible to regulate the barrels.

On barrel sleeves: they are an easy mod, but they make the "rifle" handle terribly. The weight is very much weight-forward, and the rifle won't handle well at all.
 
We started the same project, did almost as Hansel says above, however we didn't thread the mono or the barrels, just press fit and solder. Barrels are tapered with a rib between. We used wedges to try to regulate, but didn't get them real close. Fitting the extractors and regulating took the fun out of it. It's still a work in progress that my grandson picks up once in a while but puts it down before getting very far.
I have talked with Butch Searcy a few times about this project but haven't been able to git-r dun. Maybe this winter, Mark

9.3, what weight did your double rifle end up with the 30-30 barrels installed? Any chance you have a pic or two that you could post? I've been eyeing a couple of BSS' lately and it's tempting to get one converted.
