Baffel for Lee Pro Auto Disk Powder Measure...

[Rook]

My Lee Pro Auto Disk Powder Measure does a great job but I do have to keep the hopper close to full to get really consistent powder drops. I decided to try using a baffle that takes the weight of the powder instead of the bottom of the hopper. I've only tried it once with CFE223 powder but so far I'm getting consistent drops whether it's full or nearing empty.

I was loading using double disks today with two .82 holes stacked which with CFE223 it drops a little over 25 grains of powder which I'm using as a starting load for some .223 rounds. After getting the powder settled down I recorded my first 13 loads and spot checked the rest and they were pretty consistent. My Amston electronic scales will measure grains in the hundreths.

25.26 "

25.22 "

I spot checked after this and continued to get drops between 25.22 to 25.28 down to where the hopper was approx. 3/4 empty before I started getting some lighter loads.

I found the baffles on E-bay that somebody has done a pretty good job making. They fit the Lee round hoppers perfectly. I got 2 of them for $9.99 with free shipping.

Nice baffle , I have 4 auto discs on each of my turrets and the baffles do help no doubt . I ordered mine from Amazon and they are a double baffle (prairie dog 6-102 ) for $11 each, yours is a way better price though.

I've got 6 of the older Auto Disk with the square type hoppers and one of the Auto Drums but I like the Pro Auto Disk better than the others.

I did convert my old square hoppers to be able to use the brass thumb nuts instead of using a screw driver to install them. I cut the heads off of the machine screws that are used on the Pro Auto Disk and screwed them into the holes of the square hoppers with JB Weld.
