The SDD-2 die is a version of the serrator/draw die which
can serrate just the mouth of a bullet jacket, ejecting the jacket
back out after serrating a certain distance toward the base.
The bullet jacket is serrated after seating the core, but before
the point is formed. The die fits into the press ram. The inter-
nal punch is a loose fit, serving only as an ejector.
The jacket (of a specific wall thickness, but any reasonable
length) guides the tip of the punch through the serrator. The
ram should not be run up and down without a jacket in place to
align the internal punch.

and is critical: do not

The depth of cut is set at the factory and should not be
changed. Too much depth will cause the jacket to collapse or
bend, and stick in the die or on the punch. The purpose is to
make shallow cuts which act as stress risers and cause the
jacket to peel back along the lines, on impact. The jacket should
be placed mouth down into the die, and the external punch
used to gently push the jacket down as far as desired without
actually entering the die. On the down stroke, the internal
punch enters the jacket mouth and pushes the jacket out. Use
Corbin Swage Lube on the OD of the jacket to ease the pressure. Brush out the ID of the die to remove chips.
