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 powder
funnel producing a bell. The more the
powder die is adjusted down (clockwise)
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, Continued
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 re-
sistance 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 ad-
just 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
on the case mouth without falling off
and to keep the case from shaving lead
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 re-
duces the amount of belling – down in-
creases the amount of belling.
Fig. 49 - You don’t need any more expansion
than what you see in this photograph.

bell.

Too much bell.
