On the Lee, once a disk is in place it will drop a steady powder charge. However if I need to use less powder, the next lower amount is .6 to.7 gr less. I didnt mean that there was a variance of .6 to .7gr with each throw.
For example, I'm currently loading a 9mm round and I'm using 6.0gr, I wanted to use less powder so I dropped down to the next smaller size, that size yielded a 5.3gr charge. I'm not able to do a 5.7gr that I wanted for the specific bullet that I was using.
I was asking if the Dillon could be set up at whatever target weight that you wanted. I understand the +/- .1gr variance.
