I'm working up load data for a couple powders in a sorta-wildcat cartridge (7.62x40WT) in an AR platform. With this in mind, it could be under- or over-gassed (excessively slow or fast powder).
As I've been working up, I've twice seen a jam that is completely unique in my experience. The mouth of a fired cartridge engages the inside of the charging handle nose, the head of the cartridge stays on (or re-engages) the bolt face, and the BCG hangs half-shut. Of course this can't be cleared from the charging handle; you need to pull the BCG back through the port.
So, what does this FtEject suggest to you? Something about gas supply, or the bolt perhaps? The bolt appears fine, ejector and extractor are good as far as I can tell. It's occurred with recipes that usually eject and lock back, and both with and without a magazine in the well.
Edited for Spelling, thanks @jmr40
