Don Heath sounds like a twit, right there. But that's fairly standard when that stuff gets posted up.
And no, it doesn't matter who he is, or what he's done.
Any rifle could be handed to someone with no experience, and have loading it be an issue. Who "frantically trying to thrust cartridges into the mag" and expects zero issues.
It's been seen more often than not with CRF rifles, and ones with claw type extractors, than ones without. Frantic indeed.
