Supplemental chambers in .22 caliber, and potentially .17 caliber as well, pose a special problem not shared by larger calibers. Rimfire cartridges, with their low cost, noise, and recoil, are ideal for use in a supplemental chamber, except for the fact that the firearm in question is almost certainly a centerfire design.
Bill Wylde of Greenup, Illinois, compared the two cartridges and changed the chamber of the rifle's barrel to a specification he called the .223 Wylde chamber. The chamber is made with the external dimensions and leade angle found in the military 5.56×45mm NATO cartridge and the 0.2240 in (5.69 mm) freebore diameter found in the civilian SAAMI.

The WASR-22 or AK-22 Trainer is a .22 Long Rifle, semi-automatic cadet rifle loosely based upon the AK-47 and manufactured in Romania by Cugir Arms Factory. [8] Unlike the AK-47, it uses a simple blowback method of operation. As such, it has no gas system and the internal components have been modified accordingly.
The prototype for the .220 Swift was developed in 1934–35 by Grosvenor Wotkyns who necked down the .250-3000 Savage as a means of achieving very high velocities. However the final commercial version developed by Winchester is based on the 6mm Lee Navy cartridge necked down, but besides inheriting headspacing on its rim from the parent, a feature already considered obsolete by 1930s, the ...
Handloading is possible with 5.7×28mm ammunition, and 5.7 mm (0.22 in) bullets are widely available due to use in .223 Remington and 5.56×45mm NATO cartridges. [10] Handloaders have noted that the 5.7×28mm cartridge is very sensitive to small changes in powder charge or overall length (OAL) with a bullet inserted. [ 47 ]
