The RCBS MatchMaster Full-Length Bushing Die Set for .223 Rem/5.56 NATO (RCBS part no. 11108) is built for the long-range precision handloader, combining full-length case sizing with the neck-tension control of a bushing die. It builds on the familiar RCBS Gold Medal die line, so a .223 Rem/5.56 NATO shooter already running Gold Medal dies gets the same sizing pedigree with bushing-neck flexibility added on top. Full-length sizing bumps the shoulder back to set correct headspace for reliable chambering, while the interchangeable neck bushing lets tension be matched to the brass rather than a fixed expander. Part of RCBS‘s line of reloading dies.
