These problems were rectified in a very few years, and CCI ammo, as well as Winchester and several other makes, now cycles just fine in my two guns. Winchester brand ammo did not exhibit this problem, which probably resulted from differences in the brass recipe used in the cartridge cases. 22WMR ammo wouldn't completely activate the slide in the ejection cycle. When the AutoMag II first hit the market, CCI. AMT always explained in their user manuals, 'USE ONLY. By the time the chamber wall has been released by the brass' 'memory' springing back to its normal state, the bullet has left the barrel, pressure has dropped to a safe level, and the ejection cycle continues as normal. Upon firing, the cartridge case expands into the indents as well as against the chamber wall, thus gripping the wall of the chamber. The AutoMag II's chamber has a series of small indents in its chamber walls. SO to overcome the problem of blowback before the bullet leaves the barrel, AMT showed a little bit of design genius.
22 Magnum requires a very heavy and bulky slide as an inertial damper, but AMT wanted to keep their guns slim, trim, attractive and appealing.
22 Magnum handguns on the market because of the difficulty in the blowback systems typically seen in auto-loading rimfires. These guns, along with a 2' barreled version, were still listed in the 2000 Guns & Ammo Annual, but they had unfortunately disappeared by the time the 2001 G&A Annual was published. The two auto handguns pictured in the accompanying photos, the 4' barreled version and the 6' barreled version, were purchased years ago. 22 Magnum handguns were available from AMT (Arcadia Machine & Tool) of Irwindale, CA. It wasn't very long ago that some very well-designed little.
