AUTO CHARGE®PRO
The new Hornady®Auto Charge®Pro provides precise, customizable powder
dispensing in an easy-to-use, space-saving unit. Precise to within 0.1 grain, the Auto
Charge®Pro offers customizable trickle speeds for various powder types, as well as
custom time settings. Store settings for up to four custom loads or use the factory
setting. The backlit touch screen is easy to read, while a large knob on the side
simplifies powder emptying. Other features include large powder capacity, built-in
bubble level and smaller footprint than competing brands.
IMPORTANT SAFETY FUNCTIONS
WARNING - Before operating the unit, please carefully read and
understand this document.
• NEVER use with black powder – for smokeless powder only.
• Do not store powder in clear powder hopper for extended periods. Powder can
absorb moisture from the air or eventually attack the plastic. Remove powder
after every loading session.
• Internal components are very sensitive. Do not shake, drop, or overload unit.
• Handle unit with care, treating it as the sensitive instrument it is.
• If spilled powder gets inside unit, do not operate. Call Hornady Customer Service
at 1-800-338-3220.
POWER SUPPLY (Adapter):
Input: AC100-240V - 50Hz/60Hz
Output: DC 9V 1A
TIPS TO IMPROVE PERFORMANCE
• Fluctuations in temperature, even of a few degrees, can cause scale readings to
vary. While scale can be used immediately, optimal performance will occur after
unit has warmed up for 5-15 minutes.
• Always place the scale on a flat, level, and stable surface when in operation.
• Electrical interference can cause scale readings to vary. Keep other electronic
devices (power strips, florescent lights, motors, radios, phones, etc.) away from
scale when in operation.
• Do not let a fan, air conditioner, heater, or open window blow on scale.
• Using clear cover over powder pan will improve accuracy and lessen effects of
outside variables.

QUICK START
• Verify unit is properly assembled with scale plate, powder pan, and clear powder
hopper in place.
• Turn unit on by removing the powder pan, plugging it in and pressing black power
button on front of unit. For best performance, allow unit to stabilize for 5-15
minutes before use.
• Calibration is recommended before each use. (See Calibration Section.)
• Ensure powder pan is on scale and that actual weight reading (right side of
display) reads “0.0.” If not, touch ZERO/CALIBRATE button.
• Verify that powder hopper empty nozzle (at rear, right side) is closed. Fill clear
powder hopper until powder is visible at bottom of clear hopper. Fill higher if
loading many rounds.
• Check to be sure that “Setting” reads “Normal.”
• Tap TARGET button in upper left corner.
• Enter Target Weight using numerical keypad. Last number entered should be
decimal amount of charge: xx.X. Press ENTER to store Target Weight.
• Tap DISPENSE to begin dispensing entered powder charge.
• Should dispensed charge be greater than 0.1 of a grain above targeted amount,
“OVER” will be displayed. Press ENTER to remove “OVER” warning. Then, either
dump charge into powder tube and re-dispense or remove a small amount of
powder, and press and hold DISPENSE to trickle to desired weight.
• Do not use “OVER” charges.

begin to trickle.
Larger Number - Longer Trickle Time, Higher Accuracy
Smaller Number - Shorter Trickler Time, Lower Accuracy
SETTING: Tap SETTING to toggle between Normal, 1,2,3,4. The settings you are
currently using are displayed above the SETTING button. Settings 1,2,3,4 are

CALIBRATION
• For optimal performance, turn
unit on and allow 5-15 minutes to
warmup.
• Verify powder pan has been
removed, and that the red scale
plate is empty.
• Press ZERO/CALIBRATE button for
three seconds until unit displays
“CAL---“.
• When 10.00g is flashing, place
the 10g weight on the center of
the scale plate. The unit will show
“---- --” while calibrating the
10gweight.
• When 10.00g appears again,
remove theweight.
• When 50.00g is flashing, place
the 50g weight on the center of
the scale plate. The unit will show
“---- --” while calibrating the
50gweight.
• When 50.00g appears again,
remove theweight
• After calibration, the unit will
briefly display “PASS” before
returning to normaloperation.

CLEANING
It is very important that the powder is cleaned out of the Auto Charge Pro after each
use. The Auto Charge Pro should not be used as a powder storage device. To easily
clean out the unit perform the following steps.
• Slide Auto Charge to the edge of a table, with the Powder Empty Spout hanging
over the edge of the table.
• Hold the proper powder container below the Powder Empty Spout, and slowly
rotate the spout so that the powder will dump into the container.
• Once the powder has been emptied out of the hopper, close the powder empty
spout.
• Place the powder pan on the Auto Charge as if a charge is going to be thrown.
• Touch DISPENSE on the screen to empty out the trickle tube. If the charge weight
is smaller than the amount of powder left in the tube, this will need to be repeated
more than once.
• After all powder is out of the trickle tube, repeat steps 1 and 2 to remove the rest of
the powder.
• At this time, remove the powder hopper and use the included brush to clean out the
rest of the powder from the hopper.
• Close the powder empty spout when finished.
