Just got my new RCBS FL dies for my 7mmSTW. I used Redding for the last week and complained about the out of alignment of the expander ball with the body causing my neck to knocked out of round. These are my first set of Redding FL dies. No matter what I try, I always come back to RCBS. These FL Dies are good for thier money. The Expander ball seems in perfect alignment, and it knocks the shoulder back .002" from fireformed cases.

I plan to send the reddings back to see if they can fix that wobble.

Only thing I don't like about the RCBS, is they seem to overwork the neck. They compress too much before expanding back out.
