22 Winchester Automatic ammunition, also known as 22 Winchester auto, or the 22 Win Auto, is a round that was developed in 1903 for the Winchester 1903 semi automatic rifle. The 22 Winchester auto was never chambered in another firearm and has quickly become a favorite of gun collectors and Americana collectors. Today, the semi automatic rifle remains popular among a cult following always looking for a new run of 22 Winchester automatic.

The round was quite popular at the time, derived to ensure the Winchester 1903 rifle would function. Traditional 22 cartridges of the time utilized a filthy black powder that would quickly gum up the action of the Winchester 1903 rifles. The rifle’s tight tolerances demanded a clean firing round that would remain accurate, quiet, and low recoiling.

22 Winchester automatic matches the performance of a standard 22 Long rifle cartridge, but dimensionally the cartridge’s shell is quite a bit bigger. The two advantages of the 22 Win Auto was the fact it could push a slightly heavier round at the same velocity your standard 22 could. The second was the fact it was a semi-automatic rifle that offered a rapid method of follow up shots for small game hunting.

    I hustled this ammo to the range to try in my 1919 vintage Winchester 1903. I had previously only done very limited shooting with old Remington ammunition from green and red boxes. The new ammunition struck exactly to the same Point of Aim as the old. Function was perfect and there were no dud rounds, weak reports, or any other problems. All empty cases ejected uniformly about four to five feet and slightly forward. I fired at 25 and 50 yards from a rest, and got a 10 round 1&3/4" group, with eight of ten landing in about 1&1/2 ". My rifle has a smooth shiny bore, but only factory open sights. I'm almost 63 and wear glasses, and struggle to see open sights clearly, so the gun/load combo is much more accurate than I can show. But I'm happy to be able to shoot such a well made rifle again after years of sitting.

    Have been looking for a long time for this extremely hard to find round. could not be happier to have found it here. It has performed well in my 1903 and have not had any issues with performance. pull trigger, goes bang, and cycles well.
