different times there is a chance your size die setting could vary thus giving
the user inconsistent results.
5. Insert the case to be trimmed. Push the
case and bushing against the compres-
sion spring with even pressure until the
case bottoms out. (pic 7) Observe the
distance from the case mouth to the
cutter head. (pic 8) If the case mouth
IS contacting the cutter head, turn the
adjustment wheel clockwise until the cut-
ter is barely contacting the case mouth.
If the case mouth IS NOT contacting the
cutter turn the adjustment wheel count-
er-clockwise until the cutter barely touch-
es the case mouth.
TRIMMING TIP: when setting the initial
cutting depth make sure you have fully
compressed the spring; repeat this step
a few times, to ensure the proper initial setting.
6. Once you have your initial setting turn your adjustment wheel count-
er-clockwise one graduation mark. Turn trimmer to the highest RPM set-
ting and compress the case into the bushing with even pressure and trim.
TRIMMING TIP: Using even pressure each time you trim a case will help
the user achieve clean and consistent trim lengths each time.
7. Remove the case and measure your case again, compare that with the start
length of the case that you made note of earlier. Your case should be at
least .001” shorter.
TRIMMING TIP: Always trim at the highest RPM setting. If you observe
chatter on the case mouth, slowly adjust RPM down until chatter is gone.
8. Once you have measured the case, you can now set the adjustment wheel
the correct number of graduation marks in order to achieve your correct trim
length.
TRIMMING TIP: Here is an example of steps 5,6,7,8: .270 Win case with
untrimmed length of 2.546”. Initial setting completed, adjustment wheel is
turned one graduation mark, then trim a case. Trimmed case measures
2.545”. Turn adjustment wheel counter-clockwise 15 graduation marks (trim
to length for .270 Win is 2.530”). Trim case and measure. Your case should
now measure 2.530”. Your trimmer is now set to trim your .270 Win cases
to the correct trim to length of 2.530”. With some practice and using firm
