Precise Bullet Seating for Long-Range Applications Micrometer Adjustment and Floating Seating Stem for Maximum Accuracy The RCBS MatchMaster Benchrest Seating Die with Micrometer Adjustment in caliber .338 Lapua Magnum (#16640) was specially developed for demanding reloaders who expect the highest precision, exact repeatability, and perfect cartridge geometry.
