KKM Match G34 Brass

[Spiffy]

Can someone confirm for me that the brass is supposed to look like this?  Happens with Factory WWB and my handloads. I know it's just soot but I have never had an aftermarket barrel before so I'm ignorant of these things.

It's probably just blow by. Commonly happens when shooting lighter loads. It happens because the case pressure is so light that the case does not expand to the size of the chamber. Not really a problem. It can be caused by a chamber out of spec (too big), but that is WAY less likely.

I have also noticed it.  We me sometimes it depends on the powder I am using.  Faster or Slower.  I see it in my 45 loads using Bullseye.   Which leads me to believe from the above post it is changing the expansion.

Well a loose chamber is ok for what I want it for. I got it to shoot any and all bullet types in my glock.

I shoot a 34 with a KKM, and that's what my brass looks like.

When I shoot minor 40 with my 22 or 35, some of my brass looks like that.

I think timcalhoun might be right.

 

Are these the rounds you loaded so light they'd bounce off an IDPA target at 18 yards? :pleased:

 

 

Just kidding Buddy.

 

Are you liking the reliability and accuracy of your KKM? I know I'm pleased with my LW barrels.

Nope going to be an even lighter 9mm!

Thanks that is what I looking for.  The whole "Clam down, it's supposed to be that way".
