I agree on moving at least one disk over what they list. Find the disk thats the closest to what I want to drop, if it's within .1 +/- I go with it. If it's more than .1 less than what I want I will just trickle up to my load weight.

As for as the OAL that's just where they tested the load. If you go below the tested oal it will add pressure to the load and you may need to reduce the powder charge. Longer lowers the pressure. The number one thing on oal is if it will chamber and work in your gun.

The auto pro is very accurate once you know what the disk drops. When you find what they drop write it down for future reference. Do this for every powder that you use and soon you will have a handy reference to go by. Good luck.
