Good words Shadow, Geeman and my_old_glock.

Glocks are built handle SAAMI standard ammo.  My Glock 20 and 29 are both stock and run everything I throw at them just fine.

My Wtiness guns are capable of handling much more pressure, but that doesn't mean it is a good idea to run a steady diet of such ammo.

Underwood fills a place in the market.  I appreciate their product and their work.  But I take their statements that their ammo is within SAAMI spec with a grain of salt.  When you mass produce ammo that close to the line, you are going to have a "flyer" now and then.

   I'm reaching over to knock on some wood but... I have shot everything everyone else has, typically more of it and some stuff others haven't. I have yet to blow up a gun  :o  Have I been extremely lucky or got through a bad one then somehow?

IC, you were lucky enough to find those setback rounds that were in the PPU brass, beforehand.  Sort of the same situation could have happened to you if you had not! :o

It might be better to have the brass shear and vent gasses before the pressure gets too high.


I think this is true.  Glocks spit the magazine out, soot things up a bunch, crack out the poly frame, but generally the person shooting it walk away mainly unharmed.

If a witness blew up, I'd guess the barrel would split and take a hand or two with it. 

I haven't heard of a witness blowing up, but if one did, I'd guess it would be nasty.

Someone wanted to see a pic of the brass.  This was mine.

   Something happened on a Hunter once here and I think it didn't do anything other than pop the magazine out. Let me see if I can find it.

I had a KaBoom with a Ruger LCP 380, I have to take responsibility for that one.  It was a culmination of factors,load was too hot for a bullet that was too heavy in a brass that was substandard...
Having a 128 grain cast hollow point bullet register velocity 1037 fps & 1038 fps (casing blowout) for this piece as a tad too much...The guts of the magazine blew out, leaving the steel body inside was probably a good thing.  Yes it stung like hell, sooted my hand and fingers as there isn't much to hold on to with that little pistol!  The polymer frame did suffer a hairline crack.
BTW, Ruger wouldn't sell me the replacement frame even though it was a non serialized part, however they replaced it for free.

The discolored brass is a PPU with a bulge, was the first test shot, had I found it I would never had shot the second round (MFS brass with a weird bottom formation) which had the blow out...


Here is a view of the bullet to show what I was loading; Not only heavy but long for this small cartridge.

I did work a useable load for this bullet using less powder that does 810 fps the energy is 182 ft lbs

Knocking on wood with you.

    Off the top of my head bad stuff found before such events and pulled out:

- Precision One undercharged .357 Magnum rounds. I think I had two or three with almost no powder.
- PPU 10mm with some not up to par brass that could have allowed set-back.  (this was from a so called commercial reloader)
- Underwood .44 Magnum with bullets not fully seated. I'm not sure of what could have happened there.
- Underwood 10mm squib round. I got lucky I wasn't hot-rodding and stopped immediately after hearing the poof. It took some work at home getting it out!

    I generally look every box over now when I get them. Maybe I should do a pull test on the bullet? I also often weigh every round to see if I have anything way off in weight. If it's a new to me round, suspect, or supposedly loaded hot, I put on the Kevlar gloves and do my firing. More and more I'm thinking the gloves should always be worn when shooting 10mm/hot-loads.

Just to clear up the PPU issue it was not a factory loading but rather was from a so called commercial reloader.

Not an option for those of us who (sometimes) carry 10mm.

That 10mm brass in the photos is impressively thick near the aft end (and a good ways from the groove).

Intercooler,I added some info to your post about the PPU (that was reloads that were in PPU brass) May 2014
Also you sent 3 LAX rounds that the bullets were set back, for documentation.  May 2014
Jan 2015 there was DT load that would not chamber too.
Dec 2013 there were some reloads you sent that were way over crimped that wouldn't chamber.
