Practical Applications posted a rare occurrence and managed to capture it on video.
A shooter was shooting an indoor match when a loose round exploded in his pocket.
We came up with 3 possible scenarios.
1. Freak ricochet from a 2″ angle cross beam on the very back of the backstop flew back and set off the round.
Even though we were past the standard 10 yards away from hitting any steel.
2. Something possibly set off the cartridge in his pocket.
3. Spontaneous detonation.
What do you think happened?
Here is the exploded casing.
