Ruptured case

[10mmLife]

I was at the range today shooting my Walther
WMP .22WMR pistol when it fired what think may have been out of battery. The back of the case ruptured and a small piece of brass or burning powder put a small cut in my chin. I was shooting Winchester Super X ammo when this happened. Does anyone have a theory of what may have happened? I've never encountered this before.

That is the exact same thing that happened to me a while back with the RIA 22 mag pistol. I was shooting some old arsmcor i had. everyone blamed the ammo.

I think OOB would have bulged more of the case than that.

I’d put money on a faulty case…

sorry to hear @10mmLife - guessing as Hans said faulty case, or, too much primer.

 

[Belt Fed]

Mine did bulge it some. glad you're ok

 

[10mmLife]

The rim was about double the thickness than an unfired round so it definitely bulged.

You can definitely see the bulge in that one pic.

This is the perfect reminder as to why we should wear safety glasses while shooting. There was burnt powder on my glasses too.

 

[HansGruber]

Yeah, out of battery looks to be a more likely after seeing those pictures…

Question is, was it the ammo or the gun…

I racked the slide and I slowly moved it forward while consistently pulling the trigger and the hammer would strike about 1/2" from fully closing. I think it maybe the pistol.

I'm going to message Walther and Winchester and send them both pics. I dont plan on shooting the pistol until Walther looks at it. Theres a small gouge under the slide that wasnt there prior to today that is sharp as a razor.

I took mine back to the gun shop and told em i didn't want it back, they gave me my money back on another brand.

I bought it at Bass Pro last year around Black Friday. Its been an awesome, accurate, reliable pistol until today.

I only had mine a couple days and it did it on the fifth round. or about there. blew my hand almost off the grip and crack my shooting glasses.

Did you have the same pistol as me?

Glad you are ok!

I’ve had that happen three times over the years with long rifle rounds. The last one blew the extractor, spring and plunger out of the bolt of my old Remington 597 and nearly blew my eardrum out. I know where was my ear protection.

Mine was a Rock island armory 1911 22 mag.
