doublegunshop.com - home Forums General Discussion Double Rifles, Paradox Guns & Gauge Rifles @ doublegunshop.com Rifled shotgun barrels?

With the advent of the vast array of saboted rounds for 12 and 20 ga shotguns, and realizing that they shoot very well, is it not possible to simply replace the barrels on a existing 20 ga gun and have a very servisable double rifle?

Yes I understand the dificulty of regulation but would not the whole project be easy except for the regulation. And you'd have a gun, assuming a 20 ga, that aproximates a .444 marlin or similar?

(The following is typed with a grin.) It's real easy. All you do is send the gun and the money to the correct gunsmith and in a few months to a year you'll get your 20ga double rifle back. Cost= sleeving new rifled barrels into the old monoblock $1500- 2000, cost of two new barrels $200- 300, cost for ammo and regulating $100 to 500.

The grin might look more like a smirk?

OK, so I'm ignorant, started life that way and am still working on it.

So my next question will be be just as dumb. The reason I asked the 20 ga question is that what I really want, and no I do not want one of those frilly looking things and I do not want something that weighs a tone, is a O/U double rifle that has the sturdy American look of a Ruger Red Label. I do not see any reason such could not be built on a 28 ga action, assuming the action is up to the pressures. And I'm not interested in some sort of dangeroius game round but rather a mild shooting round suitable for what we've got here in NE Florida. .35 Rem is my first choice.

Crazy....maybe, but I like the double for the same reason all of you who are more knowledgable like it, it's in the details that we differ. Kind of like arguing over what hair color you like on a woman even though we've agreed on the big issue of liking women!!

Fishdock,I know you had a good question. I really meant it tongue in cheek. Thats the problem with words on a screen, you can't hear the nuances. Have you looked at the EAA over and unders? I believe they come in 308 and 30-06 for about $450 - 500? Its a cheap easy way if you don't mind them stacked instead of side by side. Then if you like it well enough you could look for something you really want. Just a suggestion.

Is this what you are looking for. I am currently building a 20 bore on a Olsen Maneng.

Mike Harrel,
There's an old guy down in Sterling that I met at the Plamer Gun Show that has done several conversions just like the one pictured above. I saw a 20ga there pretty reasonable too. He said he's done more ,,, like a 45-120.. I think his name was John? Any idea what his last name or contact #'s are?
Thanks

I know it was tongue in cheek, so was the reply......

It took me a while to get back to this because the wife and I ran back to the woods for the last couple of hours of light. She got a hog with her single shot 20 ga, rifled barrel and a red dot sight. 75 yards and it went not a foot. Just finished boning it out.

As for the gun question. I actually like the idea of a O/U better. And after seing what that sabot did ( It was one of those Hornady 265 grain SST jobs. ) I'm very convinced it would be more than up to the task.

So is there a guy who can convert a O/U into something like the picture.

And I have to ask....how well regulated are the barrrels on that 20? I understand that is the really hard part.

Sorry can't help you. I do rifles also, the one i posted was regulated for the Black Magic Brenneke. Imake cape guns also. I have one iam building in 12 gauge x 4570 with20 in bbls. Rich

I would suggest a 38-55 ,it is a rimmed ctg. with the power of the 35, would make a great ctg, or 356 Win. Rich

The gun is a twelve gauge regulated for the Black Magic Brenneke (upper right target ) sold to a doctor in Maine, am presently building him a 20 bore on a Olsen Maneng action. Rich


This one is a 45-70

So you do S/S conversions but not O/U?

Reason? I'm guessing the O/U action has some issues?

And If I may...how regulated is that 20 ga? 2 inches at 50 or better?

And if you change loads you're dead in the water....unless you ger real lucky??

Thats correct, some times you get lucky, o/us are the same, the rifles can get 1 inch at 100 yds. Rich.

22 cal. minature

Fishdock back up one page i posted target, new at this pictures game ,ill get it one of these days. An o/u can be done Rich

So you have done a number on S/S actions but no O/U...why?

And I am ignorant about some of this but if you stick with lower pressure rounds doesn't that open up the field of actions that can be used?

Not that a 38-55 or a 35 Rem is not a whole lot higher pressure than a 20 ga but they are much lower than, say a .308??

I think our posts are crossing.

I went to the Shot Show this weekend in Orlando and the Conn. Shotgun Company had a miniture .22 there that was partially finished. I think 4 1/2 pounds. It still needed extractors and firing pins and more....

And let me tell you, the Shot Show was something. It took us 2 days, all day, to work our way through it.

Fishdock, my 4570 are for high pressure rounds (mariln etc. )I only build on rimmed cases, have done o/u but there are factory o/u out there. the sxs are the hardest to build, thats why there are none. I am a died in the wool sxs hunter. I am semi retired now, have been a Gunsmith for 42 years, i only do doubles now. Got to go lock up the shop, talk to you later. Rich
I will post some pics. of the twenty gauge tommorrow, i have 2 to build. The 22 is 27 in long, the action is 1 in. wide, lenth of pull 8 1/2 in , bbls 16 in.

AkMike the only guy that I know that does that is George. I can't think of his last name at the moment. He lives a few miles from me. When I've talked to him my impression is that he only converts LC's. We'll both be at the Palmer Lions show March 3 and 4th.

RdShow can you email me about costs and time frames? Thanks harrell68 @ acsalaska.net (Just remove the spaces) Mike

Mike, did you shoot any of those slugs yet? I am curious as to the results, or if the regullateion was close/

I have a set of 30" Hastings 12gauge barrel blanks that I am going to build into a double 12 bore. The twist is 1-34" and is optimized for Hasting's saboted slugs. I'm just in the parts gathering stage now. Am thinking of building it on a JP Sauer double...when I find one suitable to convert (or ruin trying).

I'm leaving Wednesday morning to look over a new shipment of double guns and rolling blocks just in from Europe. Among other things I'm looking for a German gun with bad barrels that would be a candidate for a double rifled shotgun receiver. They should cost about $400. If anyone wants one or a roller or nice double, PM now and give me a phone number and I'll see what there is.

Allan

Okay,

I am curious.... Can existing shotgun barrels be rifled? Then be regulated.

PS I have a .45/70 built on an IGA/Stoger 16 ga, with pac-nor barrels. It will shot the pants off of any Pedersoli.

Also...
Read W. Ellis Brown's Book Building Double RIfles on Shotgun Actions.

Jerry

Someday I'll have time and guts to try it.

Allan, Private messages don't work very well. Would you please email me.

Thanks

RD Show,

Is it feasible to put a set of rifled tubes in a Valmet O/U shotgun? They are made to take interchangeable shotgun and rifle barrels such as 30/06 and 9.3X74R. Since they are of monoblock design, could a set of barrels be inserted into the monoblock after removing the smoothbore shotgun barrels?

I have an extra set of 12 GA shotgun barrels as donor barrels.

Allan

A few years ago I worked for Legacy Sports, importer of Silma shotguns, Brescia, Italy. After a SHOT Show I bought one of the uncataloged show samples, a 12 gauge o/u boar gun with 22" cylinder-bored unrifled barrels. The upper barrel has a milled ramp front sight and a long milled groove rear sight that could probably also take some kind of special claw mount. That fall I took a 4-point buck with a Brenneke slug (two, actually) at about 35 yards quartering toward me. The slug did tear up the meat a bit but the deer dropped in its tracks. LSI no longer lists Silma and I believe the marque is no longer available in the US market. You can see the gun on the Silma website: http://www.silma.net -- look for M70 Slug model. Although it looks a little ungainly, it actually balances and shoulders nicely and patterns slugs at around 4" which seems not too bad for a smoothbore. I may have the only one on these shores, and no -- it's not for sale

To: Vol423 -- Among other Valmet/Tikka barrel sets, Russ Gould of Doublegun Headquarters is listing a set of 12 gauge Becassier barrels for the Valmet 412, one cylinder bored and one rifled. Contact him at: russ@canby.com or check the online store at

http://doublegunhq.com/

Look for item 2884. I'm a Valmet fan and have several barrel sets, including the 12/.308, but this option is new to me. If I didn't already have that Sulma slug gun I might be tempted.

I asked Russ about rifled barrels before I thought of having someone convert a set of Valmet barrels. He mentioned the rifled/smooth barrel set. Kinda strange, I imagine it is for slugs and buckshot.

I think, I may be wrong, the rifled barrels are for spreading shot for hunting woodcock in thick cover. I am not sure how they would do with solids since they probably aren't truly regulated. Rifling one barrel is common for this type of application.

I have nearly finished regulation with a 20ga that I'm building on a french 16ga boxlock.
I'm sure that the second gun is always a lot easier
The right barrel is rifled and the left smooth. My thought was that unless using the high performance sabots, it is still only a 100 yard gun regardless of accuracy.

Shooting 3" Brenekes, the rifled barrel will group under 3" at 100 yards, the smooth barrel will do that at 50yd.
The rifled tube is a slow twist 1/70 from Bauska who I believe are no longer in business.
The only change that I would have made would be tubes in the left as it would have improved utility.

Cheers
Tom
