Which is one opinion, based on obviously obsolete info. .22 Winchester Auto Rimfire cartridges are available from a number of sources, Old West Scrounger being one of them. Cartridges are currently $12.95 per box of 50. Another source is Aguila Cartridges, although I do not know who handles them. Contacting them should get that answer. Each one of these rifles in a collection should have at least one box of cartridges to display with the rifle. Original boxes of Winchester loaded cartridges do bring $50 per box if in average condition. Fine examples could bring more. In your dreams! This was the only firearm ever chambered for the 22 Winchester Automatic Rimfire and these cartridges have not been made since 1932. Since it is a rimfire, you can't even get brass and load your own. You might be able to find a box occasionally from someone like the Old Western Scrounger. Is it worth $5 or $6 a round to hear the old lady go "boom"?
Yes, Cheaper than Dirt has it.
