I'm aware of the nickel test only there's a "complication"... I'm also experimenting with not
tamping: RDT/grind/WDT/spin one of those distribution tools, (depth-set to my best guess at what the headspace ought to be)/lock/pull.
I feels as if, if I add tamp to the same dose mass, it will increase head space.

It probably looks dry because the photo was taken at least ten minutes after the shot. As for the coarseness, I can't comment. It was ground with Vario with flapper mod (very very fluffy, clump-free grind pile). I've never done much post-shot forensics, (own weakness) but I can imagine that as the shot progresses, the mix of grind sizes will segregate the same way a bag of chips does, where the smaller pieces make their way to the bottom. That shot was
a little fast and could/should have been a little tighter.
