My glock blew up

I shot a co-workers glock 40 cal once, halfway through a mag - the mag popped out and the extractor flew out. He said it might have been an overcharged round cause he might not have been paying attention when using a dillion 550. Later he told me he cracked the frame and Police Supply didn't want to deal with it. The only bullets he shot out of it were cast bullets made from wheel weights.

Amazing that some take it as lightly as "shyte happens" attitude.

Most potential issues have been covered here so no need to repeat any. . I would like to add one thought that came to mind. . . If there was resizing lube still on the case or the chamber had excess oil on the surface, the case wall may not have gripped the chamber adequately directing the pressure toward the bolt. . Add this to some of the other potentials, who knows??

I don't doubt Glock will treat you right on this no matter what the cause.

Uhhh NO. The case is integral to containing the pressure. Think of it as a gasket. Cases that rupture near the base during firing release a large amount of very high pressure gas and can be quite dangerous.

I have had it happen with rifles as well as hand guns, using factory ammo and reloads and you dont even realize it happened until you look at the cases. A gasket? Well sort of, but even cracked or split it is still held in place by the chamber and bolt face, there is no way a thin brass or alum case can hold back those kinds of pressures by themselves. Like I said, many years ago manufacturers tested solid propellant rifle rounds that had no case whatsoever and or just a paper wrapping, they worked fine other than being fragile and not liking moisture or too much sunlight and now you can even get some rifle calibers with polymer cases which work fine as long as they are not used in rifles with fluted chambers. If split or cracked cases was really that much of a problem there would be a multitude of injuries considering the amount of damaged cases one finds when collecting range brass.

A split neck is no big deal. Even prior to the round being shot, a split neck is no big deal. However I guarantee you that a ruptured case head or web will get your attention right quick. Ive seen it twice and both times got peppered in the face with burning powder. The cases that lose their head likely occur after the pressure has dropped or the bottom of the case is just enough to contain the pressure.

If you think the case is simply wrapping, then drill a hole in the bottom of the case head and see what happens.

Caseless rounds require specially designed firearms.

Possible. I was using h4895 (a rifle powder) a few days before this but I did clean out the powder dispenser pretty good but I guess it would have been possible for a few grains to be left behind.

Nah, rifle powder is slower burning than pistol powder. If you mix pistol powder into a rifle powder mix, things can get interesting.

Many of the older powders contain some nitroglycerin content. The theory is that a hang fire causes the powder to smoulder and release the nitroglycerin as a vapour. The nitro vapour then detonates, which causes a massive over pressure.

This is not an easy effect to reproduce however I have personally inspected two revolvers that had the top of the cylinder as well as the top strap blown off. I'm not certain that even a double charge could accomplish that. Something else is at play in these very rare occurrences and the nitroglycerin theory is at least plausible.

This is plausible if you refuse the lessons of chemistry. Smokeless powder is made with nitrocellulose not nitroglycerine. You get all the energetic benefits of the triple nitrogen bonding, with none of the detonation killing the gun and the shooter.

This theory is like an old wives tales. Plausible if youdon't know much about chemistry.

Factory Glock barrels are unsupported.......MUST use only factory brass, when you use ####ty reloaded brass that's been fired 5 times already, the case can rupture at the rear where it's unsupported, just like your case did.

I'm sorry, you were saying ........

From Wikipedia

a new formulation that was manufactured at the Royal Gunpowder Factory at Waltham Abbey. It entered British service in 1891 as Cordite Mark 1. Its main composition was 58% Nitro-glycerine, 37% Guncotton and 3% mineral jelly. A modified version, Cordite MD, entered service in 1901, this increased guncotton to 65% and reduced nitro-glycerine to 30%, this change reduced the combustion temperature and hence erosion and barrel wear. Cordite's advantages over gunpowder were reduced maximum pressure in the chamber (hence lighter breeches, etc.) but longer high pressure.

Propellants mixtures containing nitrocellulose and nitroglycerin (detonation velocity 7,700 m/s (25,260 ft/s)) as explosive propellant ingredients are known as double-base powder.[5]:298

Next time maybe do some reading BEFORE you impugn my knowledge of gunpowder and chemistry. :(

PS. If you are gonna cite a source, you may want to actually read that source first. The very link you posted talks about double base nitroglycerin containing powders. So you used a page that specifically discusses nitroglycerin in smokeless powder to mock me for talking about nitroglycerin content in smokeless powder. Dumb!

Now I have another reason not to own that design, and I don't like them anyway.

Glock stopped making unsupported barrels since what, 2009? That said, I don't think any semi has a 100% supported barrel.

Quote from Ruger American Pistol Test, GunMag

http://www.thegunmag.com/field-test-ruger-american-9mm-innovative-duty-right/

"The chamber (of the new Ruger American Pistol) is fully supported, another good thing for handloaders and those that fire +P ammunition."

Better engineered and built to handle handloaded ammo and a steady diet of +P and +P+ ammo (as per factory web site), and this does NOT affect warranty.
 
every one arguing about cause and their pet theory gets old fast. What I would really like to know is what Glock is going to say.
as for the cause it would be nice to know as well but it has got totally overboard with the arguments.

Why not go FULL ANTI with I saw a gun explode on the internet so don't own any :rolleyes:

This I agree with. I would bet there isn't a gun make that somebody somewhere hasn't blown up at some point

None of us know for sure what caused it, we are just guessing and some may be better guess's then others.

The OP has stated that he likes to push it when it comes to the load. When you do this you may or may not like the results you get.

A wise man once told me that if you do not want to hear the answer then don't ask the question.

The best thing with this is that no one got hurt, end of story.

...that, and a $5,000 Korth wasn't harmed in the making of this thread. :p
