Glock G27 KaBoom!

http://www.youtube.com/watch?v=u5oa3D4SDzs for a full explanation as to what happened. KaBoom! that I experienced with my Glock G27 (.40 S&W) with a reload of 4.9 grains of Hodgdon Titegroup under a Rainier 165 grain Hollow Point bullet fired from Federal brass (once fired) and ignited with CCI #500 primer. An event I will never forget and will forever learn from. Cause of the KaBoom! was my negligence in over-expending the case mouth and then over-crimping. This caused insufficient neck tension and also the mouth of the case to impede the barrel throat, giving the pressure nowhere to go but out the back. I was distracted during the reloading process and proceeded to show someone how each die and station on my Hornady Lock-N-Load AP worked. In doing so, I over exaggerated the expansion and then over-crimped to compensate. I mistakenly ran 50 total rounds like this and got lucky enough to fire 9 of them. ALWAYS bench check and chamber check all the rounds in a batch until you feel that the entire run is safe to continue production. NEVER proceed to run ammo in a production during a disruption without resetting and ensure that your run wasn't compromised.
