For at least the last 10 years I've been loading APP in .32 HR mag brass for Squeaky, and after having the same results as the OP of inconsistent powder drops in the Dillon powder measure, I did some research and came up with a successful solution. Have tool heads for both .32 & .38 brass using a Lee Autodisk powder measure & Lee expander die with a 3" Lee extension. Straight thru drop and very consistant. I've shared my good experience with this setup with several BP shooters who had the same success.
