Is 6mm Flobert in the .22 family?

Long time ago someone gave me a small Anschutz rifle, like a boy's rifle kind of thing, single shot bolt action. It's marked 6mm Flobert but seems to be a .22 type chamber and bore. Chamber is very shallow, of course. Can I shoot .22 BB caps in this, if I can find some? Could the chamber be reamed out to take .22 short or better yet, .22 LR? The action looks strong enough to handle it.

Anyone ever heard of an Anschutz like this? Never seen another one, even in books, and can't find anything about it on the net.

Thanks for the info, fellas! I'll have to see if I can find some BB or CB caps and try the thing. Just set up a safe airgun backstop in my basement today so I'm all set. (Shoulda done this when the kids were much smaller--they've outgrown the thing already! Oh well, grandkids someday...:) )

I believe it's rifled. I'll have to dig it out and check. I'll try to take a couple pictures of the thing this week and post them if anyone's interested.

Think Snake!

6mm is 243 cal. .22 rounds are not known for accuracy when pushed down a large bore. Colibri and super colibre are flobert caps, but in .224 cal. RWS still makes 6mm flobert caps which are .02larger in diameter. You can always try chambering them. They work on expansion of gasses from the priming charge, Wouldn't think there would be a great pressure, especially in the larger barrel. Might split the case. ;) :)

You're not dealing with a chimp here, y'know. An empty .22LR case enters the chamber of this thing just as it would a .22LR chamber (begins to enter the chamber, anyway), and at the bore, a .22LR bullet fits just as IT would a .22LR bore. If it were a true .243 bore both would be LOOSE. In fact I could prolly drop a 22LR round down the bore up to the rim, which of course I CAN'T.

RWS sure seems to be calling .22CB caps "6mm."

Just measured the The 6 mm CB CAPS that I have ,unfired this case measures 5.65mm the bullet measures 5.60mm. the bb cap measures 5.67
unfired . the fired case expanded in the chamber to 5.82 .
A.22 Wolf MT unfired case measures 5.68mm bullet at base of case measures
5.64 mm
thats as close to 6.mm as I CAN FIGURE. BTW the RWS cases are made of
copper softer than brass. Remember that the 223 that we use in the m16
AR 15/ is called the 5.56mm tolerances vary. example take a .30 cal for various 30 cal you will find diameters from .307/.308/.311/ 312 etc.

6mm is the size of the case

The 6mm Flobert was the original designation for what is now known as the .22BB cap. Most firearms made after 1890 chambered 6mm Flobert were chambered for the 6mm Flobert Conical, now known as .22CB. It sounds as if you have a turn-of-century Parlor Rifle. Most of the Parlor Rifles do not have sufficiant strength to withstand modern .22 rimfire ammunition. Additionally, many 6mm Flobert Parlor Rifles are highly sought after collectors items, and command huge prices. Please carefully research your rifle before modifying it, it may be worth several thousand dollars.

Would LOVE to research it but have hit a wall--can't find ANYTHING about this one. Please hook me up with someone who wants to pay me several thousand dollars for it! :)

I would start with Shooter's Bible, Gun Collector's Guide, and Book of Gun Prices. Yours may be worth only a few hundred dollars but many are worth much more. Anschutz should also be able to supply information if you mail them a compleat description with all measurements and markings included, some of the proofs and stamps can be well hidden. Take pictures.

Check old (c. 1930s) AR issues

The amount of difficult-to-access info found in old issues of The American Rifleman is incredible. They used to review all sorts of European rifles and pistols before WWII and the 6m/m Flobert and Bosquette (as well as their .22 BB and CB siblings) features here and there. The December issue included a comprehensive INDEX of all the articles printed during each year.

I am interested in the 6m/m because I inherited a Flobert-type single shot pistol, many years ago. It shoots the RWS BBs, CBs (both 6m/m and .22 cal. Floberts w/17-Grains) as well as the Sellier & Belliot .22 Floberts (w/copper washed 18-Grains), very accurately for up to 15 meters. The RWS CB .22s bulge a tad, occasionally, requiring a cleaning rod for extraction. RWS BBs and S&B .22s (Flobert) work flawlessly, however. Go figure.

I am attached to this 'parlor' pistol with its Mexican-style trigger (like a Derringer), as it was my first rimfire. It opened a wide range of backyard fun in my early teens, which eventually led to the Long Rifle via the .22 Winchester Automatic (my second rimfire)!
