As you use the Auto-disk more and more, it will develope a dusty glaze of powder/carbon on the walls and all static issues will go away.
I load the exact same combination as you are using and like it a lot. W231 may be a little dirty, but there are worse options out there.
+/- .1 gr. seems to be widely considered about as tight a tolerance as any volumetric powder measure can hold....
Unless you're already quite a bit over the published max charge, +.2 gr. should be well within the factor of safety built into the SAMMI chamber pressure limits.
Were you trying to force the auto index shaft back in when you broke the square hole plastic bushing?

And if it doesn't fall with a solid "clunk" or falls in soo deeply that the cartridge base is below the barrel hood, then you have too much "crimp". (The "too deep" test is approximate. Chamber closing is the real acid test.")Your neck tension may be ok. It's not uncommon to pull a bullet with one good whack, and bullet seating requires a lot less pull than resizing.
Just make sure you can chamber the round by dropping it into your barrel. It's called the klunk test. If it fails to easily fall fully into the chamber, then you need more taper crimp.
I'll echo what SSN Vet said, the bump on the up stroke of the handle is the flare hitting on the way out of the die. If I get that I lessen the flare. That makes me feel better about not wearing out brass too fast and having neck tension problems.
