Station 5 - Adjustment of the Powder
Die/Powder Funnel
Note: Adjusting the powder die for
a straight wall case is not the same as
adjusting a powder die for a bottle-
necked case. This is because straight
wall cases are given a bell and bottle-
necked cases are not given a bell.
For the powder bar to properly dis-
pense a measured powder charge, the
powder bar must travel its full distance.
To travel its full distance, the white cube
must contact the powder measure body
(see arrow FIG 52).
Also the belling process does not
begin until after the powder bar has trav-
eled its full distance. The angled portion
on the bottom of the powder funnel (Fig.
53) is what bells the cartridge. Once the
white cube has contacted the powder
measure body the case is forced upward
against the tapered portion of the pow-
der funnel producing a bell. The more
the powder die is adjusted down (clock-
wise) the more the case will be belled.
Note: If the powder die is not adjusted
down far enough to cause the powder
bar to travel its full distance the powder
charge will be erratic and the case will
not receive enough bell.
Station 5 - Adjustment of the Powder
Die/Powder Funnel Cont...
Drop a case into the casefeed funnel
and cycle the handle twice. The case
should now be in the shellplate at
Station 2.
Move the handle down. Notice the
resistance at the end of the down stroke.
This is the resistance of the case in the
sizing die. Raise the handle. The case
will index to Station 3.
Cycle the handle to advance the case
to Station 4. Again, cycle the handle to
prime the case and index it to Station 5.
Cycle the handle.
If the white cube has not traveled its
full distance, raise the toolhead just
enough to pull the case off of the pow-
der funnel (this will prevent the
shellplate from indexing while you
adjust the powder die). While holding
the powder measure, turn the die down
1/8 of a turn. Again lower the toolhead
and observe the travel of the powder
bar.
Repeat as needed until the powder
bar travels its full distance, Fig. 52.
Once the powder bar travels fully
across you should continue to adjust
the powder die for the desired amount
of bell (turn the powder die 1/8 of a
turn at a time). The desired amount bell
is just enough to allow the bullet to sit
Fig. 51 - When properly adjusted, the
case mouth will go past the expanding
line and the stem will contact the bottom
of the case.

the end of its travel.
Fig. 53 - Adjusting the powder die up
reduces the amount of belling – down
increases the amount of belling.
A
Correct amount
of bell.
B
Not enough bell.
C
Too much bell.

than what you see in this photograph.
