Dillon Rapid Trim 1200B Case Trimmer
Connect the power cords and turn the
motor on.
Trim a case and check it for overall length
in a case gage. To check for overall length, set
the case firmly into the case gage and set the
gage on a clean, flat surface. The case mouth
should be between the high and low step of
the case gage (see page 10 for further infor-
mation on reading a case gage).
Adjust the motor up or down and repeat
these steps until the right overall length is
achieved. Once the right length is reached,
lock the motor jam nut. Before turning the
unit on, always retighten the motor jam nut.
NOTE: The vacuum assembly clamps
around the lower bell of the trimmer motor
assembly. It should surround the chip exhaust
port on the trim die. The vacuum attachment
may need to be modified to fit your vacuum
cleaner model.
Now that your cases have been
trimmed to length, you’ll need to
decap them and expand the case
mouth. To do this properly you
need to make sure that the sizing
die does not contact the shoul-
der of the case and change the
headspacing. To prevent this
from happening, thread the size
die down until it makes contact
with the case and then back it up
1/2 a turn and lock in place.
