Buddies Glock 19 barrel had a nice little bulge in it about an inch in front of the end of the chamber. I thought at first he maybe had a squib, followed by a round that pushed it out but bulged the barrel, but he says he felt a light round(reload), so he took his barrel out and checked to make sure it wasn't a squib. The following round was a definite hot round, and he said his slide stuck back.
He finally got it apart and noticed the bulge in the barrel. I've shot thousands of these reloads out of my glocks, sigs, and springfields without issue so I know the load is good. However, we had a reloading day a while back where it was super humid in my shop and we kept getting sticking powder in my powder measure. I felt like I measured and corrected any bad ones, but he helps me reload and doesn't quite have the experienced eyes that I do when it comes to looking in 9mm cases after the powder drop. So my thought is he had a light powder drop, followed by a heavy and didn't notice. We only reloaded about 200-300 rounds as I called it quits due to the humidity issue.
My question is... why did it bulge so far forward? It would seem the pressure would have gone down a bit by then? Is that the weakest part of the barrel? Did he maybe have a bad barrel? I highly doubt it was a full double charge, but maybe 1.5 charge.
Load is 124gr Hi-tek coated TC's. 3.7gr Titegroup.
In the pics, you can see the dark ring where the bulge is.
