It was Lehigh's fault (mostly), and partially Underwood's fault. Live and learn. Good thing the guy wasn't hurt.

Specifically, the projectile diameter was undersized. Even though the case was properly crimped, the bullet was easily pressed down into the casing (bullet setback) when the round fed into the chamber and this caused a sufficient spike in pressure to do the damage seen above.

Almost always a Glock. In the shot of the brass in the chamber I didn't even see primer flattening. Hopefully more details come out. Makes me want to bust my gloves out when shooting the 10's.

Wow! As the article suggested, fortunate for the shooter, the Glock 20 absorbed most of the 'kaboom's blast'.   

FWIW, since I have chosen not to reload, I try to buy the best factory ammo I'm able to. Keith from Underwood, who has been an upfront guy for years, stepped to the plate and there's a lot to be said about him and the company.

I had an 'issue' last year with an undercharged round and when this occurred, I stopped shooting the Underwood 10mm 165gr Gold Dot JHP, contacted Keith and they took back what I had and replaced it with similar ammo.

Like many others, we rely on excellent ammo for our own, our family's protection and self defense, whether it be in the city or in the back country.  I hope that Underwood further tightens up their 'quality control', so there's absolutely no issue with their ammo.

More and more I'm using my Glock 20SF as my primary home defense pistol, of course, with other firearms as backup.  I like the 10mm round for its versatility and 'results'.  Like many others, we always want our pistols to go bang when we pull the trigger with no problems or reservation what-so-ever.

Good to see that the shooter is OK.

That shot is not with the brass from the incident.  That is an unfired round.  The author is just showing that the barrel seems undamaged from the incident.

I would love to see the brass, but given that he was shooting in a snow covered area, I would guess it was not recovered.

Wow... lucky he has fingers still.

I do reload, and the one thing I do when working up loads near the top end is to wear my mechanic gloves... people would ask why, a I guess this video is a good answer.

(  I also do the bench press ( measure then push round against bench and measure again ) with new rounds to see if any setback occurs )

[The_Shadow]

The nose shape is such that it could easily get hung up or snag during feeding, thus leading to setback issues.
These also have friction reducing bands instead of full length diameters...

Another done December 9th 2015 also Length 0.6270"/Dia. 0.3995": 115gr XP

Both of these were less than the 0.4000" for normal diameters...while 0.0005" is not that much less,a loss fit in the casing could also contribute to the situation.

Reason why all my 10s are steel warriors. And thats not the 1st Glock I seen or heard of doing that !! And what I don't get is there is soooo much bad talk on here about the Colt Delta Elite not being able to take hot loads , crack frames, not a full supported barrel etc etc.
Well maybe there was a few cracked frames with the Delta but that was in the 80s !!! and just how many were there ?? 100s or 1000s anyone know? All I know is that I haven't seen or heard of the any of the newer Delta Elites having any problems like that.
Just glad he wasn't hurt and had good sense to have Shooting Glasses on.

Maybe there are more Glock Kabooms because there are more Glocks out there.

Could very well be. But I still like an all Steel Gun when shooting hot 10s

That was not a Glock barrel the gun KB'd with.

You can't blame Glock for that one.

Underwood and Lehigh are to blame.

Underwood stepped up. That is HUGE in my book.

Are there any pictures of the casing?

[Geeman]

The whole thing is a little too familiar to me.  The carbon imprints on the hand where ever there was a way for the gasses to escape.  Look on his trigger finger where the trigger safety sets.  Mine did the same thing.  I had perfect square mag release scorch marks where the mag release sets in the hand. 

The other thing he mentioned was the sting.  It felt a lot like getting stung by a baseball bat.

Its clear his was worse than mine.  My mag wasn't split, the frame was cracked in a few places, but not splintered.  My ejector went to places unknown. 

Sounds like the same cause.  Bullet setback due to insufficient tension on the crimp.

Hope that's the only gun I ever blow up.  Its not fun..

When my HiPoint 4095 Carbine blew my hands stung as well. I only imagine a full power 10mm round!
