I read a while back about someone wanting to know about problems with .40 S&W rounds blowing out. Yes, it is true. Here in my hometown, at the local indoor range, it is happening quite often. In fact, it happened to me last Thursday. On mine, I attributed the blown case to a Glock case that I probably reloaded when resized to get the bulge out, it stretches the case and weakens it. Thank goodness I had a strong pistol and not a plastic gun. All it did was a loud "POOF" and blew burned powder all over me. A very tiny piece of brass, I think, hit me on the nose and caused it to bleed a little, but other than that, no problem. A week before a guy had a brand new Glock with factory ammo and it blew up the whole gun. The factory sent a rep over and bought him a new gun and paid his doctor bill to get his hand sewn up. Yesterday I saw some 9mm on the floor with blown out cases. Yall be careful out there. Evey time you pull that trigger, a potential bomb might go off.
