With my Lee 1000 I have a set of powder measure disks for the auto disk powder measurer. It is a setof 4 disks marked A,B,C,D, the increments on these disks are .32, .34,.40 ect. all the way up to 1.57. My question is what do these #s mean? When I look a load data it says somthing like 6.6gr of whatever type of powder or somthing similiar!

How do I use my disks to get the right amount of powder?:confused:

Thanks!!!!!
 
Just use the numbers as an idea of how big they are compared to each other; once you have your powder chosen, you'll have to "bracket" the load you want, then decide on which cavity will give you the throw closest to what you need. It'll mean dumping the hopper out, unscrewing it, then moving the disk to another cavity at least 3 times, but once it's set, you'll never need to screw with it again (unless you change to another powder). Once you've got it set, throw and weigh a string of charges to make sure it's consistent, then you're good to go.
 
The numbers on the disk cavities are just a reference point...the higher the number, the more the volume of powder they will measure.
If you get the full instructions for the Lee Pro Auto-Disk powder measure, they have a complete table on the reverse side showing which disk cavity to use for which powder. There are approx. 70 different brands and types of powders listed. Don't "over think" it...As SDC says above, just start with the recommended disk cavity and then weigh the dropped charge. If it's too low, go to the next larger disk cavity...if too low, go to the next smallest. Once you have the charge you want, write the info down in a load book. ;)
If you find a copy of Lee's "Modern Reloading", it also gives the "start" disk cavity right beside the powder you want to use.
If you need more clarification, PM me. :)

Edited to add: AH, I see that acrashb has posted a link to the instructions.... :D
 
The numbers on the disks are Cubic Centimeters..ie .46 = .46cc. you will need to calibrate your powder to determine the disk cavity required for the weight of the charge. The lee manual explains how to do this. Be sure to always use a scale to double check.
