Has anyone heard of the warranty on a glock being voided by using cast bullets?

GLOCK does not recommend the use of unjacketed lead ammunition. The use of reloaded ammunition will void the warranty....

Now is the cast round from a MFG, or yours?
If yours - would they then consider that reloaded?

uzimon,

Factory ammo? What caused the KB?

The best theory I've heard regarding glocks and cast lead bullets is that the lead builds up in the chamber/throat area (or flakes off and lands there). This causes the gun to be slightly out of battery (Glocks can fire out of battery), and ....Kablooey!!! Hammered guns have less of a problem with firing out of battery because the hammer has the effect of driving them into battery where as a striker will actually push the gun further out of battery.

You can shoot lead bullets out of a Glock. Just not many, and use high quality hard cast ones. Oh and make sure you wear safety glasses.

Thanks for the infor. Very helpful.
Think I will stick with my 1911's.

If you want to shoot cast bullets, get an aftermarket barrel such as one made by Lone Wolf. (I have two and they work great!) The rifling in the Glock barrel is the problem--it leads heavily with cast bullets. Don't worry about the warranty.

I've seen more 1911 jamming with any bullet kind than Glock exploding. heh.

Informal Action Pistol shoot last weekend.
All the Glocks worked fine
All the XDs worked fine
All the CZs worked fine
All the Rugers worked fine
Not all the 1911s worked fine.

Glocks weren't intended to fire cast lead bullets. Militaries do not use lead bullets, and law enforcement does not either.

My G22 let loose while shooting cast bullets. Warantee voided. Replacement was offered by glock at their cost. $230 if I remember correctly. I don't believe it was the cast bullet but rather the unsupported case web that was the cause. Certainly lead build up could have contributed to pressure increase--If this hadn't happened on the first magazine in a clean gun.

I reckon you have not seen very many correctly tuned Government Models. Seems maybe you are looking for an argument?

Nearly all manufacturers tell you not to shoot reloaded ammo. That's simply a CYA move on their part. Now with a Glock, some say the polygonal rifling they use that can result in a lead build up which contributes to the gun firing slightly out of battery and thus a kaboom.

Lead build up in the chamber? Solution: Clean yer guns!

Guess thats why I like my XDs the best Springfield will honor the warranty on everything but modified components and after thousands of handloaded laser cast 180s through my .40 I never have to be distracted waitin for a kaboom right outa the box no need to by aftermarket barrels etc... just open the box load the mag and go shoot...... no worries bout unsupported chambers, no lead buildin up concerns no outa battery detonation issues to be watching for just a relaxing stress free shooting experience maybe thats why I can outshoot my Tucson PD buddies they are simply not able to focus on their shooting cause they are to distracted makin sure their G22s don't go kaboom ;)

+1 I personally have shot a G21 with 10,000+ lead rounds through it. The owner put a Lone Wolf barrel in and ended up taking it out and replacing it with a Glock barrel. The Lone Wolf would not function reliably. Speaking of that, if you are around enough IDPA or IPSC matchs you will see every brand of pistol jam. I'm an RSO and have seen Glocks, 1911's, XD's, HP's, etc jam at some point. Our running joke is "Glocks don't jam, if you clean them."

I think it's due to the polygonal rifling in the Glocks. Use a plated bullet when you reload.

That's exactly the reason. Due to the varied dips in the barrel lead for some reason or another has a tendency to get stuck in the grooves and can lead to problems. Welcome to the high road btw Ski.

No doubt the polygonal rifling but...

is it because of excessive pressure
or
firing out of battery?

and then the feed ramp intrusion probably doesn't help in either case.

Glocks work exactly as designed. The are intended to fire jacketed ammo and only factory new at that (no recycled brass). Initially they were designed to be a military sidearm produced in mass quantities (and later LE applications).
