I have the exact same setup as you with the same dies. I set it up to where you could put a piece of paper between the die and the shell plate (Hornady progressive press)/ shell holder (Hornady single stage). I don't "Literally" put a piece up paper into it, but I get it close. I personally don't allow the die to touch the shell plate/holder, but it's darn close.I'm fairly new to reloading. I'm getting ready to start reloading .243 for my Rem. 700 SPS V.
My question is that I see a lot of people setting up there sizing die by raising the ram and turning in the sizing die until it touches the shell holder then lowering the ram and turning in the sizing die another 1/8 to 1/4 turn. I recently took a local NRA certified reloading class and the instructor suggested this method but does not have experience with the Hornady dies I will be using.
In the instructions that come with the Hornady dies it says to screw the die down until it touches the shell holder when the ram is at its highest position without camming over them lower the ram and tighten the lock ring and its set.
Which way do I need to setup my die for proper resizing to insure a safe and accurate headspace?
That will work for you on everything you are loading. Hope that helps.
