I regularly pickup unfired 22lr's at the range. Seems people are too lazy to pick up ammo that was dropped or didn't fire. I have a powder can full.
Yesterday there was half a box of un fired 22s laying there. No firing pin strikes, just bent bullets. Useless to be tried again. The other thing they had in common is there are all winchesters. Is it the ammo or the gun? maybe a combo?
