4064 is one of the worst for consistent throws, it's grains are so course.
You'll have to accept that if the powder is your best performer.
If 4064 is bad (and I agree stick powders can be a PITA in a powder measure) then Vv n-570 is a disaster.
It's one of the coarsest stick powders I've ever used. It stacks up in my Uniflow, won't flow at all. As posted before, I unscrew the drop tube, dump into a scale pan, tweak the load then use a funnel to get it in the case.
I do love how Ramshot powders meter.
