I will also give top marks to Redding. They really put a lot of effort into very close tolerances, more so than any other brand, excepting some specialized benchrest competition dies.
If you use cast/swaged bullets, you'll get a better fit without squeezing the bullet base using Redding dies.
I agree with the first response that the dual carbide ring dies are excellent. So are the Pro Series, if you use a progressive press, like Dillon. (Incidentally, Redding are the only other dies recommended by name by Dillon besides their own dies.)

Best Regards,
Jim
