Hornady New Dimension Custom Grade Dies - Manual (Page 5)

SEATING WITHOUT A CRIMP
1 Insert a sized case into the shell holder and lower the handle
and back out the seater adjustment screw. If you have the
seater adjustment screw too low to start, you may run out
of adjustment.
2 Thread the seating die into the press until you feel
resistance. At that point, the crimp ring has come in contact
with the mouth of the case.
3 Back the die out of the press one turn to prevent the case
from being crimped — tighten the die body lock ring. Raise
the handle and return the ram to its starting position.
4 Insert a bullet in the case mouth - lower the handle so
the cartridge and bullet enter the alignment sleeve. Upon
completion of the stroke, the bullet should be barely seated
in the case.
5 Adjust the seater adjustment screw down in small
increments, each time operating the handle until the bullet
is seated to the desired length. At the completion of each
stroke, inspect the cartridge for the correct overall length.
