Have them for all my calibers. Wouldn't be without them for absolute accuracy and EASE of loading.
Reddings are my personal favorite of the factory type, and they make making adjustments so much easier because of the floating supporting sleeve and the micrometer tops.
Probably the best set to get is the Redding Competition Neck die set. It comes with a comp neck sizer, comp seater, and a body die for just pushing the shoulder back without touching the neck. I use this last die just when the brass won't go back in the chamber and I push the shoulder back only about .001-.002"
The bushings mentioned earlier also have many, many advantages that can be found on Redding website: www.reddingreloading.com
