The Forster 6 Creedmoor ULT Ultra Micrometer Seater Die – 6mm is a non-crimping style seater die that has been designed to hold your bullet and case in perfect alignment while the bullet is press-fit seated.
A handy micrometer fixes the bullet seating depth to your specifications. After you have seated your bullet close to the desired depth and measured it, simply adjust the Micrometer stem up or down to the desired depth and the cartridge will be exactly the length you need.
