I'm not so scientific with it...

Been working with my ADL lately...

I just make a dummy round...seat it long, and then ram it home in the chamber single fed...

that gives me what the throat length is...

put that in the press and adjust down until I touch the bullet.. then turn the seating adjustment down a hair and call it a day...

and leave the dummy round in the die box for reference, until I'm changing bullets...

I usually buy the TNTs in the larger box with 750 bullets...
and I have a couple of those... so I'll be shooting the TNTs a while...

75 grain HPs seem to be pretty close.. I'd buy those instead if they came in the boxes of 750...
