Im not sure what to even label my failure on the range today, so I am calling it a ‘catastrophic’ jam till someone corrects me! Further, this was due to my carelessness, I think.
I was doing load development this week and was on the range today again. My load was over press by quite a bit …. see attachment #1
My gas system was very much overgassed. To the point where my cases were being dented at the mouth by the brass defector …. see #3 attachment.
The result was a case jammed that I could not get to extract at the range and had to take my AR apart to finally get the spent case out of the chamber …. see attachment #2. Does the case remind you of other images of 6mm ARC cases people have posted?
I think that the banding we have seen occasionally is due to overgassed ARs with a hot load. The over gassing causes the case to start extracting too soon. What do you think?
