I have also heard that can happen by shooting once fired brass from a Glock into a Glock again. That is why I don't own a Glock and is why I went with my Springfield and the of course with my 1911 there after. If a person only shoots factory that is one thing. But for reloads I passed on the Glock. Then third, as much as you shoot I have no doubt that you actually had a group that tight at 40'. I would just like to see them closer next time.
I am glad your good to go.
It is my understanding that this problem with Glocks was concerning .40SW, a much higher pressure round. Also this was on older Glocks and the problem reportedly has been since rectified.
I have reloaded somewhere around 100k rounds of .45 ACP, all of it in at least once fired, and a bunch of many times fired cases. I have seen failures like this on three occasions. Two, including mine were from overcharged or doublecharged cases. The third was from a badly overthroated 1911.
If a case has been subjected to an overpressure situation, whether from excessive charging, or being un-supported, it will show obvious bulging on one side of the case head area.
This piece of brass looks exactly like the one I had, which I know from back checking what I did, was overcharged.
