Neither of my measues has a baffle but I learned a long time ago to make sure the powder is settled in the measure before trying to set a charge weight . With powders like Unique it takes a lot of tapping a cycling the measure to settle it in but it does settle in to where it's useable and safe . In use I normally don't let the powder level fall below half and with light fluffy powder it takes a lot of cycles to bring the added powder where it's being measured .
I think the lesson to me learned here is be consistant and watch for details . Great thread guys !
