Setting headspace with FL sizing die

[bigedp51]

Yes, that will work. The cheaper option however is to simply short stroke the press so the case does not go all the way to shell holder contact. If you look at the case neck you can see how far down the neck is being sized. Just size 2/3 of the neck and continue that practice "until there is a bit more Bolt resistance then you want".

Sunray is that you, what a great idea, just eye ball it and take a wild a$$ guess.

I really like the part about more bolt resistance than you want.
