on the front of the trimmer and twist the case holder in towards the blade to
shorten the cases, or out away from the blade to lengthen the cases. Using the
witness marks engraved in the face of the trimmer body, each 45º of case holder
rotation will change the length 0.009”. Tighten the jam nut and try a few more
cases. Repeat the process as necessary. Once the case length is set, rotate the
trimmer onto its bottom. In the new position, the trimmer shaft will be vertical.
See Fig. 3.
The trimmer case holder is spring
loaded as a safety feature to
prevent the case mouth from
contacting the blade until the user
is ready to trim cases. The case
holder is made up of four separate
parts that are used as a single
case holder. The outer body of
the case holder threads into the
trimmer body and is adjusted to
control overall length of the
trimmed case. The inner sleeve
of the case holder is contoured
with a chambering reamer of the
appropriate caliber to hold the
case. A light compression spring
is held captive between the two parts and forces the inner sleeve away from the
cutter until pressure is applied to a case as it is inserted into the case holder. A
small internal snap ring contains the inner sleeve inside the outer body of the
case holder. See Fig. 4 and 5.
