The Automatic Processing Press is your first choice for primer pocket swaging, bullet sizing and single stage reloading.

The APP gets its speedy operation in part by the use of the X-press shell holder. The shell holder allows the case to pass through the shell holder after the operations are performed. The X-press shell holders are sold separately.

The Lee Automatic Processing Press is fastest and easiest way to prepare cases and size cast bullets. It is also a very convenient single station reloading press.


  • Press
  • Automation Kit
  • Bottle Adapter

The first press of its kind, patentented press (Patent # 10,076,781 B1), with the ability to mount the die to the top or bottom of the press. This die mounting flexibility allows previously unheard of automation on a single station press. Now you can deprime, prime primer pocket swage, bulge bust or size cast bullets as fast as you can operate the lever.

The press is actually heavy for its compact size. It is manufactured from a variety of materials best suited for the application. The lever or handles are made of steel and are topped with a molded grip we call the power grip. We went through a lot of iterations to come up with a really comfortable design. The grip is completely symmetrical making either hand operation a delight. The upper and lower die carriers are aluminum and the low stress items are nylon or acetal copolymer. The upper carrier rides on two centerless ground and roller burnished columns. The upper die carrier is counter balanced by a centrally mounted coil spring. The counter balance prevents the handle from falling and pinching a finger.

The APP is a "frameless" design with nearly all the forces going directly to the dies through the steel linkages rather than through the frame. As a single stage reloading press it has almost unlimited visibility and hand clearance. Mounting is easy on any bench or table with no under swing.  Dirty, gritty, lead contaminated spent primers are 100% captured in a screw top bottle. 

The top carrier and base are machined to accept Lee Breech Lock bushings, so they will accept standard 7/8-14 dies of any manufacture. The APP also uses standard press shell holders from most manufactures. Includes one Spline drive breech lock bushing and universal type shell holder quick-change adaptor.

A little over three inches of stroke allows sizing of the larger belted magnum cartridges. Priced less than nearly all single station presses makes it a perfect starter press or a perfect companion press to an expensive progressive.

Automation packageAutomation package included, making it the world’s fastest single stage press. Now you can deprime cases, size cast bullets, swage primer pockets, etc. as fast as you can cycle the lever!

Features revolutionary case and bullet feeder. Jaws automatically open and grasp the bullet or case. They then rapidly position the case or bullet into the operating position. Once in position the jaws instantly open and return for the next case or bullet. It is fascinating just cycling the press empty watching the jaws open and close as it cycles back and forth.

The APP gets its speedy operation in part by the use of the X-press shell holder. The shell holder allows the case to pass through the shell holder after the operations are performed. The X-press shell holders are sold separately.

Complete with all the feed tubes, tube supports, risers and case slider. It even includes the 22-caliber bullet feed jaws.   

Maximum case legnth is 30-06 or 2.494" to process cases

Primer Pocket Swager

APP Primer Pocket Swager

APP press works with some exclusive new products, like our new primer pocket swager. The new swager removes military primer pocket crimps automatically and as fast as you can operate the lever.

Breech lock bullet sizer

APP Close-up Bullet Sizing Breech Lock Bullet Sizer Kit

The Breech lock bullet sizer allows nose first bullet sizing and you can change size with an inexpensive punch and bullet sizer die. Nose first bullet sizing is the most accurate, distortion free and because you are pushing on the base of the bullet no special nose punches are required. On the App press bullets are sized as rapidly as you can operate the press lever. The sized bullets drop into an attached wide mouth container. This is the perfect tool for the now popular powder coated bullets.

APP Bulge Buster Kit

APP press bulge busting brass

The Lee APP Bulge Buster Kitand the appropriate Lee Carbide Factory Crimp Die restores free function of rimless cases that have low base bulges. Low base bulges usually occur from chambers that do not fully support the cartridge or cases resized in carbide dies from manufacturers other than Lee. These show a noticeable stop ring near the base. You will most likely find cases with these problems in mixed range brass.
The Lee Carbide Factory Crimp Die must be purchased separately.
**Will work with the following cases: 380 ACP, 10mm, 40 S&W, 41 AE (Use 40 S&W Factory Crimp Die), 45 ACP, 45 GAP, and 45 Win Mag.
