Case Separation

[Sarge]

In everybody’s experience will a heavy of a PCC chamber rounds if there is a piece of casing stuck in chamber?

Yes, I have seen it three times now. They are a real pain to get the case sleeve out since it gets hammered into place.

I’ve only had one case separation. The next round would not chamber. My son tried several times, so the mouth of the piece was swaged inward enough to catch it with a cleaning rod. Came right out.

Yup. I used a dental pick to get mine out

Have not had it happen to me, but another shooter at my club had one during his first match with his PCC.  It did not chamber the next round, but he didn't realize what had happened, so he kept racking and pushing it in harder with each new rack of the bolt.  He ended up needing a rod and hammer to remove it.

So it seems they won’t chamber typically. So I must have a bad chamber. Mine will fire but it necks the case down

We've had so many come in, and seen at matches. I made a tool to remove them, best thing is to sort your brass before reloading, toss ALL stepped case crap.

For those of you who have had separations, are you running a lightened bolt (or a carrier with the weight removed)?  I'm curious as to whether a lighter bolt, which would start to move sooner and cause extraction at higher pressures than a heavier one, might be part of the cause.

Yes, it will chamber (most of the time) and they will fire out of battery.

Turns out my chamber was not finish reamed or throated. All good now.

One of these now stays in range bag ever since it happened to me.

Dont forget a super long squib rod too, which I leave in the truck since its use is very rare.

Yes, I use a lightened bolt and soft buffer with my Steel Challenge loads. Early on I had several case separations with cases like these:

Aside from stepped brass, I believe Federal makes a 9mm casing with what looks like a belt or perforation ring around it. I’ve had some of those separate too, so I watch for them now. I made a removal tool for stubborn brass rings that won’t come out with a pick.

That sounds like my first PCC match...happened again on the practice range too. That gun is no longer with me.
