Christoph Funk Double Barrel Bolt Action Hunting Rifle

As part of their series on interesting weapons found at Rock Island Auction house, Forgotten Weapons has taken a look at something… A little different:

The weapon is essentially a Mauser fitted for an under barrel .22 caliber single-shot rifle with a tilting chamber action, secured by a bolt handle. While, according to Ian, the gun really doesn’t feel any less wieldy than a normal sporting rifle (I suspect his perceptions may be colored by relatively front-heavy military rifles, but who knows), I do wonder if the correct solution to the problem this combination rifle is aiming to solve isn’t just reduced charge loads for smaller game.

Given that the gun is a one-off custom piece, though, I’m sure there was a specific request involved. Perhaps the wife of the person who commissioned the rifle told him he owned too many guns, and could only have one!

    IMO that is a very useful concept! I could use it often where i hunt. I can actually imagine concept as a aftermarket drop in gun/stock kit for common hunting rifle models with some facility for adjustment like on a valmet or baikal double or combination gun to allow the owner to regulate it to the centrefire commercial rifle. The gun in the article seems very well thought out. The cocking piece was so innovative. Thank you Nathaniel for blogging it and thank you Ian for reviewing it!

    Forgotten Weapons deserves more coverage, sure, but aren’t you reposting pretty much everything he posts lately?

    • So, there’s a lot of content that I can post, including stuff from other blogs, my own content, and press releases. Every time I go to post I have a drafts folder with tens of articles that can go out. I make a decision to post what I think the readership will be most interested in.

      FW has grown a lot in the past year, and I think their recent set of RIA videos are really excellent. I know people will want to see things like the overview of the 1911. For me, I get excited every time there’s a new video because I inevitably learn something – so that goes in to how I make my decision about what to post.

      I understand the concern that I’m reposting from them too much; every time I make a draft from an FW video that goes through my head. However, this season of RIA videos are really excellent and I feel as though they deserve a lot of exposure.

      If Ian would like to chime in, I would love to hear his thoughts.

        I’m flattered to get the exposure.
        I would also point out that since I’ve been doing a new video every day, for every video you do repost there are 5 or 6 others that you aren’t. It seems like a lot, but it’s far from just auto-scraping my posts. 🙂

    I could see it as a nice hunting option for a 12 or 20ga shotgun. A poor man’s Drillings.

      Izmash or Baikal had a single barrel 20gauge .22semi auto combination gun. It was break action for shotgun with semi auto .22 in the forestock and under the barrel. Saw it on their website a few years back.

    In Washington state, a deer tag also means you can pop a grouse. I think it’s one of those old time tradition things. So it would be handy in a way.

    Whatever you post,like F. W., I learn something!!

    • Thank you, Roger. That was very kind. 🙂

    • Tassiebush

      Agreed! please keep them coming!

    Coming soon from Rossi….

    I learn something from every FW post that TFB puts up. And isn’t that what this blog is all about, after all?

    Waffen Pfeifer in Austria used to offer just such a design, though they no longer list it on their website. My only concern would be about aiming the rimfire barrel.
