Kind of forgot about this stash of 22 Czech ammo I bought back when I was heavy into milsurps.
Anyone have some of this?

I have also shot a lot of the green box Russian "Junior" ammo. I had a couple guns that didn't like it, mainly sticky extraction. Never had any that the extractor wouldn't pull, just sticky. A S&W K22 required a very strong push on the ejector rod which was kind of a shame as it grouped extremely well.
It worked fine in several bolt guns I owned, ranging from an old Winchester 67 through a newer Remington 581 and several military trainers. The real surprise was that a beat up old Hi-Standard Duramatic absolutely loves the stuff. Still have a small stash of that ammo and the Duramatic still shoots great with it!
