WARNING: Be sure you read and understand the following
BEFORE you order!
SDD-1-S serrator draw die for full length
serration of bullet jackets fits the head of your S-press.
The empty jacket fits over a long punch, which screws
into the ram. Raising the ram pushes the jacket through the die,
putting a series of shallow grooves in the side of the
jacket. Ideally these are just visible, not huge or very
deep, for best results.
It is best for short bullets (handgun) for fragmenting
or low penetration applications, for large meplat designs
with a large ejection pin, semi-wadcutter bullets, and
other styles that do NOT have a long shank. They work
best with thick walled tubing jackets, or with handgun
bullets designed for use by prison guards (to help reduce
ricochet from concrete and steel, and excessive penetration
of soft targets as in hostage situations).
Full length serration is ONLY recommended for flat base,
cup base or dish based jacketed bullets. It should not
be used with RBT bases or heel bases. The reason is that
the serrations weaken the jacket prior to the step or
boattail section being formed, and will promote cracking
and breakage during this base forming operation. Even
if the base does not appear to be harmed by serration on
the boattail portion, the jacket can be made too fragile
for accurate and safe shooting if serrations extend into
The SDD-1-S is NOT recommended for standard rifle
bullets using commercial or conventional thickness
jackets and small ejectors in the point form die. The
design can expand and stick in the point form die,
like a collet, from the pressure on the tip trying to
expand the bullet in the die, in those specific designs.
The depth of groove is adjustable but should
ideally be left at the factory setting to insure
proper operation. Very shallow grooves are sufficient.
Adjustment is primarily to allow for replacement of
the cutter tips and to make them all the same depth.
Fiddling with the depth is not recommended until you
already have a good deal of experience with tool and
the bullets have been well tested using the standard
factory setup. It is easy to try to get TOO MUCH of
a groove, which raises excessive burr material and can
cause other problems "down-stream" in the processing.
