Thank you for purchasing the Hornady Lock-NLoad™ Power Case Prep Center. Please read these
instructions before using this machine. If you have
any questions about this machine, contact us at 1-800338-3220.
Product Description:
The Hornady Lock-N-Load™ Power Case Prep Center
features a powered Case Trimmer and six work stations for the following reloading tools: Chamfer Tool,
Deburring Tool, Large & Small Primer Pocket Cleaning Heads and caliber specific case neck brushes. The
Power Case Prep Center may also be used to deburr
flash holes and uniform/ream primer pockets with optional accessories which are sold separately.
The Cam-Lock™ feature on the Hornady Lock-NLoad™ Power Case Prep Center locks the case in a
removable Shell Holder for precise trimming. The
Lock-N-Load™ Power Case Prep Center will only
work with Hornady Shell Holders. (Hornady Shell
Holders are sold separately) The Power Case Prep
Center comes with a 5/64” hex wrench and seven interchangeable pilots to accommodate .22 cal, 6mm,
.270 cal, 7mm, .30 cal, .38 cal and .45 caliber cartridges. Other pilots are available. Caliber specific
pilots are used to align the case mouth on the cutting
unit. The Hornady Lock-N-Load™ Power Case Prep
Center is engineered to help you significantly improve
the efficiency of your reloading process by combining
several essential case prep tools into one unit.
General Information About Case Trimming:
Repeated firing and reloading results in the brass of a
case flowing towards the case mouth. Reloaded cases
grow in length because of these actions. When a case
exceeds its maximum case length, it may contact the
throat of a firearm. If this happens, the case will not
release the bullet properly upon firing and chamber
pressure will subsequently increase. Whenever a case
grows longer than its maximum specified length it
must be trimmed back to a length near the minimum
for that caliber. Trim and maximum case length specifications for modern cartridges are published in the 7th
Edition Hornady Handbook of Cartridge Reloading.
Refer to this handbook for case trim specifications and
other case prep topics.
Safety Precautions:
The Hornady Lock-N-Load™ Power Case Prep Center
has been engineered with your safety in mind. The
likelihood of an injury or property damage is reduced
when these safety precautions are followed.
• Become thoroughly familiar with the machine by
studying these instructions.
• Leave the machine unplugged until you are ready
to prep cases and have read these instructions.
• Do not work on or near damp or wet surfaces.
• Plug power cord into a properly grounded outlet.
• Wear eye protection when operating the Power
Case Prep Center.
• Do not use this machine if you’re rushed for time
and don’t take shortcuts by attempting to bypass
any of these instructions.
The Hornady Lock-N-Load™ Power Case Prep Center
has an in line fuse to protect the motor from damage
when the cutter is under too much load. If you try to
trim off more than .050” at a time really fast you may
put too much load on the motor which will blow the
fuse. The fuse is a 1
glass fuse. You can purchase these at most automotive
or electronic stores. Under normal use, you should
never have to replace the fuse. NEVER USE A FUSE
LARGER THAN 1
Instructions for Powered Case Prep Center:
(1) Secure the Hornady Lock-N-Load™ Power Case
Prep Center to your reloading bench with four 1/2”
diameter bolts, nuts and washers. Select a bolt length
based on the dimensions of your reloading bench.
(2) Before you start trimming, make sure all cases
have been full-length sized or neck sized with a reloading die.
(3) Check to make sure the power cord is NOT
plugged in.

use trimmer pilot # 1 for .223 Remington. Tighten
pilot set screw with the 5/64” hex wrench. See Fig. 1.
(5) Loosen Main Adjustment Knob on the back of the
machine and turn the Main Adjust Handle Counter
Clock Wise so there is ample room between the Shell
Holder and Trimmer Pilot. See preceding photo with

When you have installed a caliber specific pilot, focus
your attention on the Position Screw which is located
on the right side of the Spindle Platform. The bottom
hole is used to accommodate short/medium cases and
the upper hole is used for long cases. To check the
initial position of the Shell Holder, insert a case into
the Shell Holder Retainer and rotate it Counter Clock
Wise to lock up the case. The slot in the Shell Holder
should be facing the front of the machine. If it is not,
pull down the T-Handle approximately 1/2” and unscrew the Position Screw. Rotate the Spindle Stop
Clock Wise until the slot in the Shell Holder faces the
front of the machine. Re-install the Position Screw in
the upper or lower hole (Fig. 2).
