Found old .22 Short in the house + mystery ammo. Can give away, if somebody wants it

I recently found some .22 Short ammo on an unused shelf in a closet in my house, which was left by the previous owner. I don't know how old these cartridges are.

If somebody is interested, PM me and I can bring them to the PA State championship match this Sunday. I can't guarantee that the ammo will work, so I will not charge for it but will give it away to someone who can use it. I don't want to go through the hassle of shipping these rounds, so this is a local offer only.





Also, I found half a box of the "mystery ammo" pictured below. Again, I have no use for it and can give it to someone who can use it. In exchange, let me know what these rounds are - I am curious.



Best Regards,

The bottom picture looks to be birdshot in an old remington box.

Looks like Federal Gameshok .22 birdshot.

I never even knew that .22 LR birdshot ammo existed! Thanks, guys!

That is called “snake shot” in our area. It’ll do a number on a rattlesnake at 15’ or less.
