Thanks for sharing this. I do not pull many, but this will definitely make me think when I do.Wear your safety glasses Boys and Girls....
This weekend, I was running the Chronograph stage at the state USPSA match. I had to pull a bullet to weigh it for my first shooter on Saturday. Put the cartridge into a kinetic bullet puller and hit it on a wood bench sitting next to me. The round detonated and shards of plastic, the collet, primer, and case went everywhere.
Luckily, everyone in the area had glasses on and I wasn't standing over it when it happened.
Over 35 years of doing this. Hundreds (if not thousands) of bullets pulled in my shop and while doing matches, and this is the first in-puller detonation that I've heard of, let alone experienced.
