I have been loading with a single stage press and a Lee Pro Auto Disk powder measure. I am going to add a Lee Classic Turret Press or Pro 1000 progressive press. Is it difficult to use a different brand of powder measure (RCBS Uniflow or Redding 3BR, for instance) with the Lee flow-through die? Do other turret mounted measures operate the same, dropping the charge on the upstroke as the case mouth is expanded like the Lee?
