Rimfire oddities any ideas ?

[Dellboy]

Anyone got any ideas what these are ?? 22 lr shown for comparison

22 winchester Auto or 22 remington auto

bullet diameter .22
neck diameter .23 ish
case diameter .248
rim diameter .31
case length .660
overall length .91

no boxes came mixed with a load of bagged up .22

so what do they fit ??

[Dellboy]

Weird one then ?

A new one on me, I've not seen its like before.
Apart from the obvious that the example you have is made by Winchester and that it appears to be a similar case diameter to .22WRM (which it obviously isn't) I can only agree with your suggestion that it's possibly a .22 Winchester Automatic, which according to cartridges of the world was dropped by Winchester in the 1970s.

Agree, looks like Winchester rimfire automatic...Wiki says 1903-1932.

It is Winchester.

Winchester rimfire ammunition has had a an "H" stamp on it since the original .44" Henry rimfire round brought in with the 1860 Henry rifle. Oliver Winchester didn't want his name on the innovative design until he was sure it was going to be a success.

Not an absolete calibre then ?
Pretty scarce so into the back of the cupboard with anothe 200 rounds i guess .

Aguila still make batches of it now and again.

Winchester .22 Automatic ammunition was introduced with the Winchester 1903 semi-auto rifle. It was Winchester's first semi-auto and at the time there was still a lot of .22 ammunition loaded with black powder which would quickly gum up the works of a semi-auto rifle. So this ammunition was introduced to stop owners from putting the black powder ammunition into these guns. Remington did a run of the same ammunition. There has not been another gun chambered for this round other than the Winchester 1903.

Box of Winchester ammunition and the 1903 rifle - a neat little take-down.
