and small powder bar, on the other hand,
are standard equipment and are included
with every XL 650. All powder measures
are shipped with small powder bars
installed . If you need to change the powder
bar – refer to “Powder Bar Adjustment” in
the Caliber Conversion Section on page 30.

E. Station 2 – Adjustment
of 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.
Adjusting the powder die for a
bottle-necked case is covered in
the rifle section.

FIG 40

For the powder bar to properly dispense 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 40).

FIG 41

Also the belling process does not begin until
after the powder bar has traveled its full dis-

tance. The angled portion on the bottom of
the powder funnel (see arrow FIG 41) 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 pro-
ducing 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 dis-
tance the powder charge will be
erratic and the case will not
receive enough bell.

To adjust the powder die/powder
funnel:

1. Drop a case into the casefeed funnel

and cycle the handle. The case
should now be in the shellplate at
Station 1.

2. Raise the platform. Notice the resis-

tance at the end of the downstroke.
This is the resistance of the case in
the sizing die. Lower the platform.
The case will index to Station 2.

3. Raise the platform. Check to see

how far the powder bar has traveled
FIG 40.

FIG 42

4. If the white cube has not traveled its

full distance, lower the platform just
enough to pull the case off of the
powder 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 FIG 42. Again
raise the platform and observe the
travel of the powder bar.

5. Repeat step four until the powder bar

travels its full distance FIG 40.

FIG 43

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 during the seating process (see “A”
FIG 43).
Note: If you screw the die down too far,

the case will look like example “C”
FIG 43. You must then discard
this case, back the powder die off,
by turning it counter-clockwise, and
continue with a new sized case.

You’ll soon learn to judge the correct

amount of bell by simply looking at it. In
the meantime, you might want to use your
dial calipers to check it. Twenty thou-
sandths of an inch greater (at the mouth of
the case) than its original diameter, should
about do it.

Correct amount of

bell.

Not enough bell.

Too much bell.
