"If you think you've lived long enough, or want to die young" is how it should read. A reduced Weatherby load might run 40 kPSI (just guessing), which is, oh, 2X what the action was designed and tested for. Yes, I know there is a book about building a double rifle from a SXS shotgun -- but I wouldn't do it.
A lot of those 'just selling these items from an estate' specials are hilarious -- 'antique gun barrels - valuable collector's items' was one I saw recently, with a bunch of old rusty barrels, you couldn't even tell what they might have come off of. Usually with a ridiculously high opening bid to boot.

Anyone who would chamber a double rifle, even a factory made double rifle for 460 WBY Mag has nothing in the attic, but cob-webs!
TODD Gthere isn't anything wrong with building a double rifle on a shot gun action. The thing, though, you must start with a quality shotgun, and use your head when chooseing the cartridge it will be chambered for! Example: I built an O/U 30-30 Win AI double on an SKB action, and it was a real jem, one of the best woods deer rifles I've ever owned. It is still kicking around in the pick-up rack of a rancher, 35 years later, without one problem. I try to buy it back at least once a yr, no deal, my friend told me he wouldn't even loan it to me, because he was afraid I wouldn't bring it back! That little rifle will place two from each barrel on a playing card @ 100 yds all day long!

I was perhaps being too polite in my criticism about the gun -- using an no-name spanish shotgun action was one mistake -- I know there are some very good Spanish shotgun makers, and then I've seen some that could just as well have come from an arms market in Afghanistan.
The second mistake being the choice of cartridge.
I do believe you could use a stout SXS shotgun action for a double rifle, I think some of the English firms of long ago did, but I would be leary of shooting it. 30/30 would be very cool for a double, BTW. Can you buy one like that?
Best, Todd

May be there were two of these rifles. Now there is one, and now we have an estate sale ..... I do like the 30-30 rifle that Mac had though, sounds sweet.
As far as I know there are no comercially made 30-30- double rifles, either S/S, or O/U available on the market to day. I have built two 30-30 AI doubles, one the SKB, and a S/S on a Luarona, both started life as a 20 ga, and both were build with 20" barrels to carry while following hounds in the mountains of New Mexico. They were perfect for that purpose, black bear, and Couger. and whitetail rifles for deep woods!
The fact is most of the best grade English shot guns were made on small rifle actions, not vice-versa. The Germans have always used the same action for all rifles, combination, or shotguns, and are hell for strong.

What are the physics of a double rifle/shotgun? If the barrels are sufficiently strong to contain the pressures how are the forces of the firing transmitted to the action? The backthrust would be going against a solid breechblock how much force is going to be trying to blow the action open? The german drillings seem to get away with 50,000 psi+ loads on those things they build. Their locking mechanism looks like a shotgun. These are just questions I was hoping someone could answer. The rifle?shotgun? that started this whole thing would be fun to put in a vise and try to blow up by working up to full power loads. Done with high speed photography it woud make for some great video as an added bonus you would get rid of an ugly gun.
