You forgot the smallest of the Winchester self-loading cartridges...the .22 Winchester Automatic cartridge for the M1903 .22 rifle. Still manufactured by Aguila and available by the 500 round brick.

These look quite similar to the standard .22 Long Rifle but come from the .22 Winchester Rimfire/.22 Winchester Magnum lineage of cartridges. The M1903 rifle was eventually manufactured in .22 LR as the Model 63 and survived into the 1960s....Taurus reproduced the M63 at some point so perhaps the M1903/M63 could be considered the most successful of Winchester's early self loader rifles
