The Hornady Lock-N-Load
®
 AP
™
 Press is designed to use 
Hornady dies as well as most other dies with a 7/8"-14 threaded 
body. However, the characteristics of each die is different and 
will determine the setup and capabilities of the press. For 
example, using the Hornady Pistol Taper Crimp/Seating Die will 
free up a station on the press so that a Powder Cop Die may be 
used. Please see the various layout options below to help locate 
your dies on the press. 
Die Mounting Instructions
For initial die cleaning and individual die adjustment 
instructions, please refer to the instruction sheet that came 
with your die set.
Lock-N-Load
®
 quick change bushing system
The Lock-N-Load
®
 system is based on the positive locking 
action of the bolt action rifle. Just like the bolt action rifle, the 
locking action is incredibly strong and simple.
Once the dies and the powder measure are adjusted for loading, 
these settings are locked in place by tightening the Lock Ring 
that is provided with all Hornady dies and powder measures.
How the Lock-N-Load
®
 works:
•  Insert the Lock-N-Load
®
 bushing into the press and turn it 
clockwise to lock it in place. 
•  Adjust the die to the desired position and lock the setting in 
place with the die’s lock ring. 
Once Lock-N-Load
®
 bushings are installed, Dies and Powder Drop 
can be removed from the press with a quick counterclockwise 
turn. Since the Lock-N-Load
®
 bushing is locked in place, the dies 
and the Powder Drop remain set exactly as you left them. 
For added speed and convenience, Hornady offers inexpensive 
Quick Change Powder Dies for use with the Case Activated 
Powder Drop.
