My first firearms related accident

[alamo5000]

I am normally an extremely meticulous reloader. I have been reloading no less than 15 years and probably longer than that. What happened here is the brass was home-formed brass made out of 223/5.56. The case walls (which became the neck) were too thick but after forming you could drop the empty case in a chamber gauge and it would look fine. Once a bullet was seated though it was too thick and would not fully chamber. It was basically an out of battery detonation. It was out of battery just enough to where the bolt was not locked so when it went off it jammed the bolt into the carrier and split it.

In no less than 15 years of reloading all the time this is my first accident. Not cool.

It took me about 4 hours to remove the bolt and carrier from the upper. I broke everything down into pieces including removing the barrel (for inspection purposes) and it appears like this bolt carrier group is the only casualty here.
