Ummm, what happened?

[xjtwo]

I went to the range last Saturday and proceeded to fire my GSG....loaded up some mags and started making golf balls jump around. After about the 6th-7th mag, I fired a few rounds then I hear a shot that didn't sound right at all. Stopped shooting, pulled the mag and cleared my weapon.....this is what I found.



I looked thru the barrel as best as I could at the range and decided that I should probably put it down. Got home, took the dewy and pushed a lodged bullet out. Proceeded to disassemble the rifle and looked for any damage......none found.

The mangled casing does not have a pin strike.......I'm at a loss trying to figure out what happened?

Looks like you left the garbage disposal on to me.

Yeah no doubt!

Never had a squib before......when it happened it sounded totally off and there was a shit load of smoke coming out.

Looks to me like there wasn't enough powder in the casing, instead of burning, it detonated (exploded). The lesser powder would explain why the bullet got jammed in the barrel.

but since the case is blown like that, I don't know how tight the chamber is on a GSG. it definitely isn't enough to have the casing blow apart like that. Did you mangle it pulling it out?

If not, then it makes me think a failure of the gun...the round went off as advertised, but was not supported in the chamber (either a delayed fire (very possible), or an early strike of the primer while inserting the round into the chamber (a lot more possible). when the case isn't supported, there isn't a lot of pressure to push the bullet through the barrel which would explain why it would get stuck. with no chamber to support the case, that would explain why it blew apart.

I am thinking it is the last guess:

some sort of failure on the guns part allowing a premature strike of the rim by the firing pin, before the round was fully inside the chamber, but luckily centered enough to allow the bullet to go down the barrel and get stuck.


double check the chamber and make sure it looks okay. take a flashlight and look closely.

also check the web and see if there have been any similar problems. i would talk to GSG on this if my guess is correct.

You got lucky you still have your eyes.

He said there is no striker mark on the case though. Can a hot chamber cook a round off?
