I bought these for a Montana that I had for a while and sold. These are basically new. I think I next sized and loaded 20 rounds. Here is the Redding description:
The Redding Type S Bushing Neck Die allows the reloader to precisely control case neck size and tension. Type S Dies use interchangeable sizing bushings that are available in .001" increments. This set includes Type S Bushing Neck Sizing Die, Body Die and Competition Seater Die. Bushing and Shellholder are sold separately.
These list for $190 new. I'll sell these for $150 shipped.
