Bad Day at the Range - KB!

Glad no one was hurt. That case shows all the signs of soft brass, and possibly a balloon head case. It may be an ammo defect from the factory, but I have seen the same sort of thing on brass that was in a fire and "salvaged" by a bargain hunter.

I don' t think the balloon heads themselves are necessarily a problem; I have fired a lot of Hungarian LC .45 with no problem and they have balloon heads. But, combined with soft brass and an unsupported case head, an accident is looking for a place to happen.

PMC in 45ACP has always worked good for me. It's lower pressure than 40S&W but performed flawlessly. I've reloaded some PMC brass with no problems but I use Speer brass now.

If you think PMC brass is bad its probably the web. A lack of web would cause the bulge. Take a bunch of mixed brass to a band saw and cut it in half. Compare the PMC web to other brands.

Oops... meant to write OAL measure at 1.122". The P99 is back in commission. I only had to replace the extractor and will go this afternoon to get back in the proverbial saddle. Thanks for all the posts. Cheers, Cryoman

There is one significant problem that you have apparently overlooked - you seem to think your pistol is a Walther, when it is OBVIOUSLY a GLOCK.

The reason that this is obvious (to a trained investigator such as myself) is that ONLY GLOCKS KB !!

Please don't take this as a flame. Everyone makes mistakes, and everyone must learn at his own pace. As you gain more experience with firearms, you may be able to spot these things too.

I would suggest getting rid of that Glock and getting a reliable handgun, such as a Walther.

Dawg23,

Point well taken. As only Glocks ever have KB!s, by definition, it MUST be a Glock..... I sure thought it was a Walther P99 but logic prevails....:D

Cheers, Cryoman
 
Well now, if it was a Glock it would have blown into a hundred pieces. Obviously the Walther held up better to the crappy PMC brass.:rolleyes: ;) :D :p :cool:
 
Well well well, a KB from something else other than a 10mm Kurtz Glock!!! Maybe it's the 10mm Kurtz!!! I don't reload, so I don't know for sure, but it seems to me that the .40S&W round destroys a lot of guns. I think I will stick to my 9mm P99 and my .45ACP G36.:D
 
One thing you may want to look at is the tighness of your case mouth on loaded rounds. When i started loading for semiautos long ago I had the die adjusted slightly wrong. The result was insufficent tension on the bullet. Bullet setback is a proven cause of KB's. Start with a full mag and drop the slide allowing a round to chamber. Pull back on the slide and eject the unfired round onto a soft area like a bed or carpet. Repeat until the mag is empty. Carefully measure the OAL of the ejected rounds. If your case neck tension is too loose you may see set back in the first loading.
NEVER, NEVER repeatedly chamber a round (like the one at the top of your carry mag). I have had Remington and Federal factory pistol ammo that allowed the bullet to be set back in a few as 3 repeated chamberings. Of course this can be a worse problem in a weapon with a steep feed ramp or a round using a bullet that has a particularly blunt profile.
