Our new range of adjustable micrometre head straight line seating dies are manufactured to suit 6mm, 6.5mm, 7mm, and 30 Cal projectiles, and some smaller and larger calibres are undergoing the design stage at present. The dies are made from 416 stainless steel and are supplied in two forms, either as a blank die that has to be reamed with your specific custom reamer or as a fully reamed die to suit specific chambers.
