SET UP
The Hornady Blackpowder Lock-N-Load
™
Powder Measure
has been designed to minimize sparking from friction and
static electricity. The hopper, its cap and the drop tubes
are aluminum. The rotor and metering unit are brass.
Though the measure is similar to the Hornady Lock-N-
Load
™
Powder Measure, parts do not interchange.
There
are clear drop tubes on the market that will fit this unit.
DO NOT USE THEM! Plastic can hold a static charge that
may cause a spark.
1
Follow cleaning instructions before use.
2
Install the drop tube of your choice, one that is as
large as it can be without allowing the case mouth into
the orifice.
3
The metering unit adjusts from ten to 50 grains in
five-grain increments, and from 50 to 130 grains in
ten-grain increments. The increments of the measure
correspond to other Blackpowder measuring devices
(10 grain, 20 grain, etc., with FFG Black Powder). Other
sizes of Blackpowder and Pyrodex will drop different
amounts. It is MANDATORY to confirm charge weight.
CLEANING INSTRUCTIONS
1
If the handle has been installed, remove the two attaching
screws and place the handle and screws aside.
2
Press the button on the side of the rotor and pull the entire
metering unit free.
3
Push the rotor free of the housing.
4
Disassemble the metering unit by removing the cap and
O-ring.
5
With a high-quality aerosol degreasing material, such
as Hornady’s One Shot
™
Gun Cleaner & Dry Lube, quality
brake cleaner, electrical contact cleaner or rubbing
alcohol, remove oil from any surface that may come in
contact with the powder. (It is not necessary to degrease
the push-button assembly.)
6
Place all parts on a clean rag and allow them to air dry.
7
Once parts are completely dry, reverse the procedure to
assemble. No lubrication is required.

OPERATION
1
The knurled nut and O-ring work with the various grooves to adjust your unit in any of the above-
mentioned charge weights.
2
A slight amount of compression should be applied to the O-ring. When the plunger is all the way in,
and the O-ring is in the first groove, there is approximately 1/2" of plunger showing outside of the
knurled nut. The unit is set to drop approximately ten grains of Blackpowder (FFG).
3
To adjust, start with the plunger all the way into the ten-grain notch. Loosen the knurled cap nut, and
pull the plunger back while slowly rotating it. Starting at ten, count 15, 20, 25, etc., until you get to
50, then count 60, 70, etc., until you get to the desired charge weight.
4
Once you have adjusted to the correct weight, tighten the knurled cap and drop two or three charges.
5
After dropping two or three charges, weigh your charge to verify that you have the correct weight.
6
When the plunger is all the way out to the last groove (about 3" beyond the nut), your Powder
Measure is set to drop approximately 130 grains (FFG).
NOTE:
Prior to setting higher capacity charges,be sure to drop the last charge, then rotate the rotor so the
plunger is in a horizontal position. If the plunger is down, you will drain the hopper.
CAUTION:
Any time you use a cleaning solvent on plastic
or rubber parts, check for chemical compatibility, prior to use.
