Re: Stoney Point thread size?
[ QUOTE ]
I am thinking fire formed brass will give a more accurate measurement of base to lands.
My Stony Point threaded brass is like .004 shorter at the shoulder than the fired cases. If I bump the shoulders .002, now I have a difference of .002. ARRRGGHHH!

For most of us, the $6.50 per furnished case (ie, ship them your fire-formed brass) is a bargain. I make a similar tool for my 50 BMG and had to purchase a hand tapper to get the required perfect alignment. Even with the proper tap and my alignment (hand tapper) tool, I wouldn't bother to cut my own threads.
