Who has found a bullet seating stem that does NOT either imprint the .308 175 Sierra TIPPED MK over a slightly compressed .308 Win load, or stick the Tipped MK bullet in the seating stem? The Hornady New Dimension Custom Grade seater die, using an optional 208-gr AMAX seating stem or the factory stem, imprints the hell out of the bullet's ogive (tangible dent ring). The Forster fully-supported National Match .308 Win seater die sticks to the bullet, HARD! I spent an hour on each seating stem with 220-grit sandpaper in attempting to remove any ridge and open up the stem mouths. No help. RCBS standard die works perfect, no ogive imprints, no stuck bullets, but I wanted a fully-cartridge-supported seating die (e.g. Forster or Hornady) to minimize bullet runout. Thoughts? - C. Smock
