So I looked at the links, no info on cause, so what was it, light primer strikes, sear stick-slip, European cartridges with their stiff primers, what?
Hangfires are quite probably the most dangerous firearm "situation" because people tend to start pointing the gun everywhere and then it goes off.
You know the 30-second rule, but a lot of people don't.
You know not to point a gun anywhere you can't fix the hole, but a lot of people don't.
