I have had situations where I know the pressures were at the Max Saami average and still had a blowout.

Ammo brass is anealed so that it can stretch to meet the chamber wall without splitting, then contract after the firing to allow easy extraction. This is a narrow state for a piece of brass to be in. And varies.

The anealing process is not suppose to be used on the base and lower wall to allow it to stay harder and stronger. But the anealing process is just a method of heating the top area of brass.

Variances in the timing/temperature or startup/stopping of this process can cause variances that are not visible to the eye.

Maybe only one in 10k pieces has some sort of issue. But you can't see it. The only way to protect against this issue is to not depend on the brass to hold the pressure(full chamber support), or back way off on the load.
Very true, too many variables...that is precisely why I purchased the StormLake, Lone Wolf Dist barrels for better chamber support for the G-29 and Bar-Sto conversions for my S&W 1006. Most of all, I practice maticulus safest loading practices possible. Why? It's my hands wrapped around the pistol.

It is still quite possible that Murphy will visit one day!

And that's why I wear Kevlar gloves when testing new "full-house" loads.

+1
Revision Sawfly glasses and kevlar/spectra lined gloves were not expensive equipment but wouldn't develop my hot 10mm loads without. In the beginning I had only Rex Magnum powder and no 10mm data for it, some hot loads were developed from scratch.
Later I switched to Vihtavuori 3N38 (for 155 and 165 gr) and N105 (for 180 and 200gr), but when crossed book max data always had gloves on as well. Glasses are always on anyway when shooting - even with 22lr

More then once I've had my cheeks peppered by particles and would have had my eye hit by spent cases if it weren't for glasses, and not just with reloads, factory ammo too.

I can't even imagine someone using TG to go off the books. Lucky is the only word I can come up with & be playing nice. Stick to printed data. Glocks are not bullet proof, JMO.

My 10 survived 16gr PP (accidental double charge) with only a cracked trigger, mag release, and extractor. I had some bruised thumbs. I do NOT recommend anyone else using that recipe.

I was using published Lyman max of 8gr PP 180gr OAL 1.255 CCI 300. I have an auto indexing press (Dillon SDB) and was having some primer misfeads due to a cracked dispenser cap. Got distracted moving things around and missed a double charge. This was prior to adding a flashlight to shine down into the cases. Honestly, my initial impression was that the gun was trashed. After breaking it down, it cost me $37 in parts to fix and a 10rd mag. I was lucky that I only got some hand damage from the shockwave. It will never happen again, but it's nice knowing that the gun could handle that much.

Thanks for sharing and glad you were not seriously hurt!

Accidents happen, at least the pictures are pure evidence of what really happens, not just "tales of high pressure" and double charge dangers.

You didn't by chance happen to be chronographing at the time?

Hey, glad you're still in one piece!

Ha! Unfortunately, no. I'd like to know how fast I was going when I packed up the pieces and got the hell out of there though! There were some Glock remnants on the range somewhere. I didn't find the follower, extractor rod, mag spring, etc. I'm sure the next guy wondered what happened.

With a load like that I wouldn't know where to even start speculating the fps.

I was wondering that, too. It actually may not have been too impressive. Since the case ruptured and the pressure was bled off in the explosion, the bullet likely wasn't going any faster than usual. But who knows, if that case held together long enough, it would be a rocket!

Bullet wasn't going as fast as you might think at first. Remember, it was acting as a bore obstruction; that's why your barrel blew. Other parts may have been going faster.

My first question today is .... who made this thread a sticky? I thought we were mod-less. Also, if this thread is a sticky, why is the .223XR thread STILL a sticky?? lol

I requested it be a sticky,

Maybe a vote to delete the .223xr sticky is in order or a request to the Mod?

MOD's name sent to you nicke10mm

As I said, requested it to who? Lol.

I guess MakeMineA10mm is still helping... Maybe.

Not a big deal, was just curious
