One day i was watching a firearms documentary and it showed how guns in Africa had multiple barrels like about 2 or 3 of different calibers. these types of firearms were made due to the scarce amount of ammunition in the area.

This idea made me think of a single shot double barrel rifle with one barrel that shoots a something like a 223 and the other one a 12 gauge for hunting. maybe something light for backpacking and even collapsible. i have been looking on the internet for fun but cant find anything, so if any one knows of anything please let me know. thank you.

After WWII the allied occupying forces were concerned that Germany might rearm for a third go around. Rules were established to limit the civilian population to one rifle, one shotgun, and one handgun. These limitations fostered a market for multi-caliber guns. Peter Stahls was probably the most successful with his multi-caliber handguns that could shoot 20 different calibers from one 1911 frame. I have a three caliber Omega 1911 set (10mm, 45 ACP, 38 Super) that can change in seconds.

Blaser and Sauer & Sons made multi-caliber rifles, that have interchangeable barrels.

Many shotguns have tube sets that allow different gauges to be used.

Other variations to consider would be the HR Handi-Rifle or the Thompson Center Contenders which offer caliber changes by swapping barrels.

Sorry but double (Cape style) guns and dreilings go back to the late 1700s and became popular when the local European royalty or nobility would decree that only one gun was allowed per household regardless of how many people resided there...They were also the standard fare for the Foresters working the aristocracy's estates as they could deal with anything encountered from fowl, fauna or humans...Their heyday came about after the introduction of the brass cased cartridge c.1850s and veirlings (four barrel) guns really not until smokeless came about c.1890s.

The British navy issued a seven barrel, flintlock, Henry Nock volley gun during the Napoleonic Wars.

Actually, just after WW2 the German people were not allowed any firearms, of any kind, and that didn't change until the 1950s in Western Germany and I don't think it happened in Eastern Germany except for party members.

France, Belgium, Italy, Germany, Austria, Russia, Sweden even Switzerland all made dreilings in vast numbers just not so many veirlings, although Britain made some they never became popular although the double barrel Cape gun (1 x shotgun and 1 x rifle) were made for Indian and African stationed civil servants and military...During WW2 the German Luftwaffe in 1941 issued the M30 dreiling, a 2x16 (and some in 12 bore) over 9.3x74Rmm, to its bomber aircrews in North Africa, made by J.P.Sauer & Sohn.

Jerry D Young--As to finflings (five barrel) I believe there are two that have ever been made and only recently and only by Peter Hofer of Ferlach, Austria...They carried a price tag of well over $250,000 so I really don't think that they are a viable item to mention.

spastical--You may be talking about the Savage 24 that came in rifle over shotgun, rifle over rifle in calibres ranging from .22 LR to .30/30 and has no been re-introduced and called the Model 42 in .22LR over .410 gauge.

Drillings and combination guns are fairly common here in Europe. Lots of good used ones floating around too. Some makers, current and past, come to mind: Merkel, Sauer & Sohn, Blaser, CZ, Brno, Antonio Zoli, Sabatti, Fabarm, (most Italian shotgun makers have an O/U combo available), the already mentioned Baikal, the Finnish Valmet 412 system, Tikka, Krieghoff, Haenel, Heym, Verney Carron.

Southern Europeans like their driven hunts, for which O/U combination guns, often with battue sights, are common. Guns like the Verney Carron Sagittaire Mixte, for example.

German drillings are excellent. I have an old J.P. Sauer & Sohn, 2x12/70 with a rifle barrel underneath, rechambered for .223. Merkel produces drillings which are nothing short of sheer brilliance and available new from the factory. Blaser has a slightly different approach (rifle barrel on top) but surely fine guns too. In Scandinavia there's a long heritage of hunting with Spitz dogs, for which business the combination gun is the tool of choice. Some specific guns for this are the Tikka M77 or the Valmet 412.

Not a longgun, but the Medusa Model 47 revolver has a pretty wide range of caliber choices if you are looking for something that helps you with "pickup ammo."

Also, check out youtube - Iraqiveteran's test of a break action .410 had is reliably shooting a host of ammo (not sure I would shoot that close to my face, though - they used string). 454cas, 444marlin, 45lc, - pretty much anything near .45 with a rim. Not very accurate though.

A diffrent suggestion

I realize it’s more fun to buy a new gun than to think about saving a few dollars but take a look at fitting tubes to a 12 gauge. Several companies make them and the cost is considerably less than a new gun. I have a ULM (pictures attached) over and under with a full set of barrels for shooting skeet that will take a variety of ‘chamber adapters’. You will be able to shoot most common cartridges from a single weapon.

Cheers Ray-man! A very, very nice gun. Is yours actually a Krieghoff, by any chance? I don't think there exists a maker named Ulm? Ulm is a city in Southern Germany and the only maker there I'm familiar with is Krieghoff. Also, the locking looks very much like a Krieghoff to me. I haven't seen anything similar on anything else but Krieghoffs and Valmets.

Yeah 12&.30-06 would be a good pair if you had to have a 2 barrel 2 cal limit on a combo gun. Bird shot can take everything a 06 is overkill for and 06 can reasonably take everything from deer on up in this continent, and if you are hunting something that can hunt you back you always have the option of Buckshot or slugs in the 12 barrel.

If you was gonna have a drilling, vierling, or a funfling maybe a smaller rifle than .30-06 for taking small stuff at longer range than birdshot could do for your 3rd cal. If you got a 4th or 5th cal I don't know what they would be.

I have to admit that multi-caliber firearms appeal to me like any other multi-use tool.

Unfortunately, most multi-use tools have significant compromises.

Most multi-caliber firearms are single shot (per caliber) so you can generally forget about them for defensive use (unless you have no other options). If the scenario is that you will have to be actively defending yourself and anybody with you, then this means that you will probably also be carrying a Personal Defense Rifle. Even if someone is with me who has a PDR, unless I have a whole squad with me (not likely when hunting) then I am going to want a PDR myself too.

If I am already carrying an AK (or AR or FN-FAL) then I see little advantage to also carrying the weight of yet another rifle as a PDR will usually be fine for many hunting purposes (except small game - in which case I have a one pound single shot .22 rimfire rifle or I could be carrying a scoped .22 rimfire handgun).

That leaves the shotgun. While I have three shotguns (two of them are O/U combo rifle shotguns) I am not a big fan of them for hunting. For many hunting purposes we use a shotgun for now (usually by law), in a SHTF situation, I believe a rifle would be better. Waiting for waterfowl to land and stay put for a few seconds gives you the chance to shoot them with a rifle. Proper hunting technique also lets you shoot other small game with a rifle that we now by law or convention shoot with a shotgun.

Multiple calibers in one long gun make the gun heavier.

Switch caliber long guns are nice, but regardless of the method, it takes time to switch, whether with an adapter or by swapping a barrel.

Many of these systems cost as much as a whole other firearm, and some of the systems weigh near what a whole other long gun would weigh (if it is lightweight). And you still have the issue of carrying a PDR.

I see the main advantage as having a firearm that will use ammo you may trade for, but even there it seems like this may be putting the cart before the horse - I prefer to always have plenty of ammo for any firearm I have rather than firearms for ammo I might get post-SHTF.

The cost of the extra barrel system/etc. (T/C barrels are about $250, Valmet barrels are considerably more expensive) will pay for either more ammo or a less expensive version of full firearm something that shoots that ammo; there are a lot of used decent to nice hunting (of various action types) or mil-surplus bolt action rifles in all kinds of chamberings you can buy fairly inexpensively - from about $100 to $500.

I agree trebuchet, now if I was still in a truck then I would definately carry one of each, but on foot i think the weight would be unmanigable therefore the compromise. I like it because if I scare up a squirrel I can use the 20Ga and if I want to be quiet and get multiple kills from a distance, I use the .22lr. .22wmr would not be bad, but I think it tears them up too much.
