CQ / Tulammo question...

[rick'o'shea]

Had my Marstar CQB to the range today (Great service BTW) and had an issue. After about 80rnds I had one stick
in the chamber. I'd been shooting both tula and norinco. It was a tula that stuck. I splintered a wood dowel trying to
knock it out at home, you can see the ejector pulled a chunk off the rim when I tried to pull it out. Anyone else experience
this? The gun is only a month old and hasn't seen more than 200rnds. I think its the lacquer build up/melting.
Thoughts?
I'll try to add a pic later, the case had a black flake all over it.

lately I been seeing 308 Tulammo I have where the rnds are out of spec in length/width (some rnds will not feed into chamber easily on multiple rifles)

Some times when firing the primer pushes back on bolt releasing gases the wrong direction other ammunition aka Norinco/Winchester are aok. Sometimes the primers come out almost 1mm

The primer on this one is still flush. You can see a ring around the case 1/4" up from the base and there's
none of that black stuff past it...

Did you clean the barrel before you began shooting? Looks like it was just gummed up really bad and the case got stuck in the "GOO"

I read a thread somewhere once that said you shouldn't switch between steel and brass cased ammo without a good cleaning or exactly this would happen. That looks like carbon to me so I would think a cleaning would solve it.

I had pulled a snake thru it but didn't actually clean the chamber..
Its clean now.

I hadn't read about switching brass/steel. But now I know.
