Problems in reloading GLOCK fired brass???????

[Darrell Davis]

Mornin' Shooters,

My son was shooting his .40 S&W at an indoor range this past week and had a case failure.

The case head seperated from the body, causing the slide to slam back and damage parts such as the ejector.

The on site gunsmith will do the repairs at a total cost of about a 100 bucks, but he also told the son that "range" brass which may have been fired in a Glock can cause potential problems, such at that experienced by Jeff, when reloaded.

I spoke with a friend about the situation, and his son used the term, "Glockized" for what Glocks do to brass fired in their chambers.

My son also said Speer's manual had a warning about reloading some brass from certain autos. I have not found that info at this point.

From what I can gather, it sounds like the Glock chambers run to the over size side and therefore allow brass to swell more then is normal in most other autos, which in turn over works and weakens the case.

Anyone have any information on this situation?

Keep em coming!

Brass from cartridges fired in a Glock can suffer what some call the guppy, a bulge in the base of the cartridge case near the head caused by the poor cartridge case support in the Glock.  I've never had an problems reloading it, it feeds fine in my S&W MP40, but I only load moderate mid range loads, you didn't mention how "warm" your load might be in the case of your failure.

He didn't mention what kind of pistol was involved, only the caliber.

To give you an idea, this is an example of Glock fired brass, NOTE that this is an extreme example, but it gives you an idea what it going on, and how the Glock leaves the case unsupported.  This extreme example was caused by a too hot load fired in a Glock, so the "guppy" effect is exaggerated.  This was a KB in the making, this shooter barely escaped blowing up his Glock.

The moral of the story - - -

if you want to shoot 10mm loads, get a 10mm Glock.

This Glock is probably for sale....

Hey, you really didn't  tell these folks it was a Beretta pistol, you left the impression that it was also a Smith and Wesson handgun. Gotta stay on top of this stuff, boy.
