thread. If you are looking at the
cutting end of the shaft, turning the
head counter clockwise while
holding the shaft will loosen the
head for removal. Turning the
head clockwise will tighten the
head for installation. As the unit
operates, the cutting forces act to
tighten the cutting head to the
trimmer shaft. It will not spin off in
normal use, so there is no need to
apply dramatic torque to the
cutting head during replacement.
Do not over tighten when
installing, a snug fit is all that is
necessary. Over tightening will
only make the unit more difficult to remove later and provides no additional
stability to the operation.
Meplat Trimming Feature
The ability to clean up the meplat surface of match hollow point projectiles can
result in better accuracy at long range. Because of this, several manufactures
offer device to trim or uniform the
meplat surface of bullets. The Giraud
Powered Case Trimmer is among
them. To trim projectile meplats,
additional parts are needed and
described below.
A cutting head with a carbide end mill
replaces the case trimming cutter head
using the interchangeable head feature.
Only one meplat cutting head is
required to trim meplats of any caliber
projectiles. It is installed using the
same spanner wrenches and process
described above for case trimmer
cutting head changing. See Fig. 8.
A projectile holder is required for each
specific caliber diameter projectile to be
meplat trimmed, i.e. .22 caliber, 6mm
caliber, etc. This projectile holder is
constructed of the same basic parts as
a cartridge case holder and is installed
in the trimmer in the same way as a
cartridge case holder, loosen the jam
nut, remove the previous holder, install
