I have had lots of 22lr ammo not fire after the first strike but never one going off by itself after the first shot.
Sounds to me like you needed to get a new firing pin spring. Those old ones are really weak and need to be replaced. The same is true with old 1903's and enfields. I have experienced a ton of hangfires until I replaced some old firing pin springs. I don't really know how to explain how a harder primer strike reduces hang fires, but for some reason it really did. I had one 1903 springfield that would hangfire my handloads. So, before you go blaming old surplus ammo, look at the gun you are shooting it from.Yup, surplus 8mm. It sucks, happened like every 5 rounds.
