[edit] Questions
A couple of questions
- Is "caliber conversion sleeve" the proper name given that it doesn't convert the calibre (bore diameter) but rather the chambering (cartridge)? Perhaps if it's in common use the misnomer is fine
- Why is the article specific to .30 cal and .32 ACP? I thought you could get these gadgets for various different combinations of rounds, e.g. 22 LR in various centerfire cartridges etc etc.

- Cartridge conversion sleeve, caliber conversion sleeve, and supplemental chamber are the only names I have seen for these devices. I have always heard them called caliber conversion sleeves, but this may not be the most common proper name. They are commonly sold today only for .30 caliber rifles to use 32 ACP.
- They are not specific to .30 cal and 32 ACP, but this is the only such device pairing that I have seen in recent years. Added a 25 auto conversion that was evidently sold until roughly WW II, so they are not unique to .30 cal and 32 ACP.
- I haven't seen one of these devices for 22 LR. There are kits sold to convert M1911A1 45 ACP to 22 LR for target practice. Likewise, there are AR-15 kits to convert them to 22 LR. However, all these 22 LR kits are complete slide, springs, and magazine swap out parts for semi-automatic actions. Unlike these, a supplemental chamber doesn't require any change of the barrel or magazine or springs, or any modifications to the bolt-action gun; you just load up the device and chamber it like any normal cartridge and shoot it.
- If cartridge conversion sleeve or some other name is more common, we can certainly move the main article. Yaf 02:40, 14 April 2006 (UTC)

- Interesting. But these appear to be chamber adaptors that stick in the chamber upon being fired. The cartridge conversion sleeve, on the other hand, does not stick in the rifle chamber, but is extracted each time to re-load another 32 ACP cartridge using the normal bolt-action extractor/ejector mechanism. No broken shell extractor is required for using the sleeve, unlike with chamber adaptors. Reminds me somewhat of the difference in flash suppressors and muzzle brakes :-) They, too, look much the same, but are treated differently by the BATF! Yaf 04:07, 14 April 2006 (UTC)
