I do admit that RCBS dies a tad better.
I picked up a set of 45-70 RCBS dies from another nut.
When the dies arrived, they were dusty with cobwebs.
I thought to myself, these things were toast.
I though wrong. A good clean up and the dies were cranking out perfect rounds for my Marlin.
The only thing i dislike about my lee dies in 9mm is the belling die.
It sticks on the downstroke and requires a quick "whip" of the arm to set it free. Probably not good for the dies or the press. That and the rings coming loose.
I'm not complaining though. I picked up a Lee hand press and the 9mm dies plus the lee cutter plus cutter guide for just under 100$. That price simply can't be beat.
60$ more and I got 500 lead cast 125 grainers and some Titegroup.
You get what you pay for, but you still get lots on a shoestring.
Your millage may vary.
