B.
The Crimp Start Die contacts the
shell holder, in which case, un-thread
die one-half to one full turn (most
pistol cases).
4.
At this point, the crimp die lock ring
can be threaded against the press and
locked.
5.
If the crimp start sleeve has not
made contact with the cartridge case
(instance 3B), thread the adjusting
screw into the die until contact is made.
6.
Obtain a “star shaped” crimp by
lowering the ram of the press and
threading the adjusting screw into
the die. Raise the ram to the top of the
stroke again. Continue this step until
the serrations in the cartridge case
come nearly to a point or the mouth of
the cartridge case is closed.
The Crimp Start Die is now set. In
some instances, the crimp start die will
sufficiently close the cartridge case to
form the blank round and no finish crimp
will be necessary.
