David has a point re powder granule size - if vibration caused a change to smaller grain size the surface area goes up - and so probably burn rate.

I ''tumble'' - vibro actually - in a Midway unit - just the fired cases and then deprime after. I do sort first tho as 9mm's and 40's love to join up! In fact too IIRC 40's like to nestle inside 45's.

Makes it hell after, separating them all again.
