New Lee Challenger ''Breech Lock'' press - 90588

The Lee Challenger Breech Lock Press 90588 is a single-stage press designed for reloading and case preparation operations. The robust O-frame closed design offers stability during operation and ample working space to comfortably handle cases of different sizes.

The Breech Lock system allows for quick die changes, reducing the need for repeated adjustments with each change.

Robust and stable O-frame

The closed O-frame structure is one of the most common configurations for single-stage presses due to its rigidity. The stated working opening is approximately 4 inches (10.16 cm), providing good clearance for inserting and removing cases.

The press is suitable for numerous operations, including:

• Case resizing
• Decapping
• Priming
• Bullet seating
• Crimping, using the appropriate die

Breech Lock quick change system

The Breech Lock Quick Change system allows you to install and remove the die with a simple twist.

Once the die is correctly adjusted within the Breech Lock bushing, it can be removed and reinstalled without having to repeat the full adjustment every time. The system is compatible with common standard 7/8 x 14 threaded dies from Lee and other manufacturers.

Lee Lever Prime priming system

The press includes the Lee Lever Prime system, designed to facilitate primer insertion during the working cycle.

The priming position is located at the front of the press, making it more accessible to the user. The system also allows for quick switching between small and large primer configurations using the appropriate accessories.

Spent primer collection

During decapping, spent primers are channeled through the ram to the collection system. This solution helps keep the workbench cleaner and tidier.

Adjustable ergonomic lever

The Lee Challenger Breech Lock features an ergonomic lever with adjustable length. This configuration allows for adapting the movement to different operations and exerting progressive and controlled pressure.

The lever linkage is made of steel to ensure durability during use.

Bench installation

The press must be securely fastened to a sturdy workbench using appropriate bolts. For consistent results, it is important to install it on a rigid surface, leaving sufficient space for the full movement of the lever.

Dies, shell holders, and other reloading accessories not expressly mentioned must be purchased separately.
