Brass perforating at the neck?

Years ago I had the same thing with a lot of W-W 284win brass. I agree with you and Mr. Valentine. I had some that got the hole after 1 firing, some after 2 firings and some it took as much as 5 firings. As I recall probably 75-80% of those cases had the exact same problem.

Lynn,

They really do shoot awesome. And, they seal well enough to have virtually no vertical at 1000.

The thing with using cases in this condition is that the gas escaping is going to cut up the neck area of the chamber.

This may be true, but, with how well these shoot, I'd say a barrel or chamber job every few groups wouldn't bother me. I don't think anything adverse has happened to my barrel, and I've shot these with the cracks in them for 2 years in my current HG. I think they've been shot 5 or 6 times in the last two years. I'd have to look back.

Even before they were split they shot some pretty impressive targets.

Back on Dennis's original topic though, the holes in the shoulder area are usually an aftereffect of having a fold in the brass that got swaged together during the draw process. I don't know if I have a good example of this anymore but if I can find one I'll post a pic of an unfired case with that exact problem Dennis showed.

I recon when I finally get to see an elephant fly I will have seen about everything because until now I had never seen this before.
I have seen dents in the shoulder of the brass from powder kernels spilling into the chamber when a round was pulled apart on extraction. But never a hole from the inside out.

Gentleman, would you believe, that even some brand new Winchester straight .44RemMag. pistol cases have splits just like these, from the inside out.

Gentleman, would you believe, that from now on some of you w'll need to have your eyes more open.

You can't be serious ?
