A. Station 1 – About the Case
Gage FIG 71:
To install and adjust a sizing/decapping
die you must have a case gage and know
how to use it. The sizing die shapes the
case. If the case doesn’t have the proper
shape it won’t fit properly in the chamber of
the rifle. The purpose of the case gage is to
determine whether or not the case has the
proper shape, which in turn will tell you if
your sizing die is properly adjusted.
Note: Case gages are caliber specific.
B. Station 1 – How to use the
Case Gage:
The way the case gage works is this:
Once you’ve made a preliminary adjust-
ment to your sizing die drop the sized case
all the way into the case gage FIG 72. Look
at the base of the case.

FIG 74
FIG 75
If the base of the case is below the high step
(see “B” FIG 73) and above the low step
(see “A” FIG 73) then the sizing die is prop-
erly adjusted. If the base of the case is
above the high step FIG 74 then you will
need to adjust the sizing die down by turn-
ing it clockwise.
FIG 76
FIG 77
If the base at the case is below low step
FIG 75 then the sizing die is adjusted
down too far and needs to be backed out
by turning it counter-clockwise (Note: this
case should be thrown away). Once the
sizing die is properly adjusted, drop the
properly sized case back into the case
gage and look at the mouth of the case FIG
76. If the case mouth is below the high
step (see “C” FIG 76) and above the low
step (see “D” FIG 76) then the case is the
proper length and will not need to be
trimmed. If the case mouth is above the
high step FIG 77 then the case mouth
needs to be trimmed in order to reduce the
overall length of the case. If you find that
your cases need to be trimmed, Dillon
Precision offers two types of case trimmers.
