Bizarre casing failure

Kashmir1008 · Jun 27, 2016

Hey folks

This came out of an HK33/53 (semi auto) that a buddy of mine owns. It's Tula .223/5.56 ammo.

I was thinking maybe he just got a bad bunch of ammo but I haven't be able to get up to the range with him yet to shoot some federal or WWB to compare.

I've never seen anything like this before and his HK will chew up and spit out pretty much anything you give it.

Thoughts?

Looks like it wasn't chambered correctly.

Tula low power, steel cased sh*t. Looks like the HK ate it (normal). Tell you Buddy to shot better ammo.

It looks like the brass got caught on the side of the ejection port, probably early in the bolt's travel forward. Most likely weak ejection from underpowered load as previously mentioned.

Had 1 in my chamber of my galil arm ( steel case) was stuck and came out that way. Thinking it short stroked and recrammed it back in the chamber. Gun felt soft on that shot.

I shoot tons of steelcase in my HKs w no issue. That round doesn't have visible striations from the fluting so something is up (well, they are only visible as the base.) Is the chamber completely fouled? There should be obvious carbon tracks and even slightly visible stretch marks on steel from the flutes. That might lead to extraction problems.

Looks like a short-stroke and fte, causing the case to jam back up instead of ejecting clear. I have had this happen with a 308AR when testing reduced power loads, not enough to properly cycle and a similar crushing experience.. LOL

If it operates properly it should be able to handle any off the shelf ammunition.

He needs to get it checked out and corrected.

I'm with smdub. The chamber might have something in it like the lacquer from steel cases in it making the gun action slow down and jam the case up. I had a similar issue with using hornady one shot where it would actually leave a residue in my gun and make cases stick where I would have to pry the bolt open. They had similar marks where the case was sticking and swelling in the chamber.

Chamber is loaded up with lacquer and carbon. It needs a good cleaning.
