My very first KA-BOOM

Wow! Glad you are ok.

As said earlier. This is a really thin chamber. My Sigp226 .22lr conversion barrel was at least double the thickness and all in stainless steel. This one looks like cheap pot metal. :/

Was just about to post the same thing Slavex. I zoomed into the first picture, and man.... that DOES look like cheap cast pot metal. A steel barrel would show more "ripping" of the metal I think.

I hope we're wrong.... who the heck makes barrels (even .22) out of pot metal!?

unfortunately many 22's are made of pot metal. gsg 1911, beretta neos, sig sauer mosquito.....
 
I was searching for other people with the same issues... it sure seems like the majority were using CCI ammmo. However since it is the reccomended ammo I think those analyses might be pretty skewed..

on a separate but possibly related note.. they do allude to their "lightweight barrel and slide" (??) and "unique locking system" in their advisory against installing suppressors:
From Keltec's website:
Quote:
USE OF A SUPPRESSOR WITH THE PMR-30 PISTOL IS NOT RECOMMENDED.
Due to the unique locking action of the PMR-30 pistol and the lightweight slide and barrel, the use of a suppressor is not recommended as it will cause an increase in gas volume and pressure and the slide will likely unlock early. This will cause an increase in gases and residue that is ejected back towards the shooters face and could also cause a case rupture to occur. Any damage or injuries caused by the use of a suppressor or other heavy weight muzzle device attached to the PMR-30 pistol will not be covered by any Warranty.

so in other words watch out for our weak barrel/slide if our unique (?) system unlocks early due to pressure ranges outside of "ideal" ranges. Because we all know how dependable and consistent .22 ammo is. LOL

interesting

seems that KelTec takes care of the USA clients with ease..... :) Hope that bodes well for you up here.

That sucks man! I do have to say that gun looks cheap as hell. never seen so many screws on a gun and there are air guns with thicker barrel walls.

Glad you're OK tho!

Yeah that seems like a royal piss off. Ohwell, just wait and see what happens.
 
I dont know if there is an aftermarket barrel for it.

I just dont understand tho, ive seen alot of youtube videos of them working just perfect (ie.... nut n fancy, hickok45, some others)

I see what you mean.. I made the mistake of assuming because it was popular in the USA that there would be other barrels available.. sorry.

looks like the only other option is with flash hider..It looks like a different type of design entirely, and maybe even more weak?

I wish you luck anyway. At least you were not hurt!
 
The amount of brass blown back against the bolt face is very curious to me. I'm not acquainted with WMR, is there enough room for an overcharge in the case? Clearly, the gasses and energy were all but used up tearing the chamber apart before they were able to send a ____? grain projectile down a 5" (?) barrel? Are these bullets crimped in I wonder?

Glad you weren't hurt, shame about your gun and I hope the dealer or manufacturer will look after you the way they should.

I asked a lot of questions about the ammo, but in my mind it shouldn't matter if the ammo was out of spec. It was the gun that failed...double load whatever, it doesn't matter, the gun should be built to take it IMHO...you know, proofing!?
 
Glad you didn't hurt.
I never think .22 mag could do this kind of damage. Looks Kel-tac barrel wasn't made from strong material.
I have to reconsider the Kel-tec product.
 
Looks to me like a case of "flash over" - ask PPC shooters about it. Large cases - small amount of powder laying throughout the length of the brass case - primer ignites but instead of the burning beginning at the aft end of the case and progressing forward "gradually" (relatively) the ignition occurs over the entire surface of the powder laying in the case and the mixture EXPLODES! VICIOUSLY! Enough to blow cylinders out of PPC REVOLVERS and destroy the pistol frame. Caused not by an OVERCHARGE of powder but when small charges of powder are used in large cases. Same potential problem exists when Smokeless powder is used in old large volume Black Powder cartridges without "packing" to hold the powder charge against the base of the case and not spread along the length of the case. A possibiity to consider.
