The RCBS MatchMaster Competition die sets are the perfect sets of dies for the
precision handloader looking to craft the most precise round possible. The
Full length sizing die utilizes RCBS’s precision-machined neck bushings to put
the perfect amount of neck tension on each round. The titanium nitride coated
expander offers silky-smooth case extraction and reduced brass build up on the
expander both of which help reduce the amount of stretch on the case neck.
Rounding out this exceptional set is the MatchMaster Competition Seating Die.
What sets the MatchMaster seating die apart from the competition is the bullet
seating window with bullet retaining system. Simply place the bullet in the
window and raise the case into the die to seat the bullet. No more smashed
fingers or misaligned bullets! Couple this with a micrometer adjustable, free-
floating, self-centering bullet seating stem and you have the easiest, most
accurate bullet seating die on the market. MatchMaster Sizing dies require
appropriate RCBS neck bushings for the caliber you are loading (sold
separately). To determine the proper neck bushing size, measure the outside
neck diameter of a loaded cartridge and subtract .002†to .003†to allow for a
small amount of brass spring back.
