Classic Cast Breech Lock Press

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

I received the patent on this new press late last year. It is the first press of its kind 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, 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.
