solution for powder charge fluctuations
At one point in the past, I was using a Lee Pro Auto Disk and getting big fluctuations in each load. (I can't remember what powder now, but it just may have been Unique??)
My solution was to simply fabricate my own little baffle to put into the powder hopper. I just took a cap off of some plastic jug and cut pieces out of the sides. The end result was that the top of the cap looked like it was supported by several little 'legs'. Drop this into the powder hopper with the legs pointing down, and whaaala... a custom baffle.
This was the only time I've ever had problems with a Lee disk-type powder measure, but it works like a charm now. Never varies more than 1/10th of a grain. I now use the baffle for every type of powder... can't hurt.
...update:
- I just checked my reloading spreadsheet, and it was Unique that gave me big fluctuations. I am willing to bet that if you try the baffle-thingy, your problems may disappear.
