How would you sneek up on this 9mm load

I used to ream out Hornady brass bushings to get the charge I wanted, but I finally broke down and bought a 10X measure.

Carefully drilling out the Lee disk should work just fine.

The Auto disk instructions say you can stack disks, but keep the larger one on top to prevent having a 'ledge' that won't drop the powder.

Actually you want to do the opposit. The disk with the smaller hole needs to be on top.

Yep, which is why Lee says to enlarge the hole partway on the bottom edge to increase the volume of one hole, as 1SOW posted earlier.

Oops, a senior moment. Sorry, you're correct of course. That's why I said drill the bottom larger.

Thanks Walkalong I didn't see that. I could have swore in post 25 it said to have the smaller hole on the bottom.
