Lee Precision 90659 Breech Lock Pro Shell Plate #16 500 S&W / 7.62 x 54R

The Lee Precision 90659 Breech Lock Pro Shell Plate #16 is a precision reloading accessory designed for handloaders working with 500 S&W Magnum and 7.62x54R ammunition. This shell plate is the interface between your press and your brass, so getting the right fit matters—it ensures consistent case positioning during the entire reloading cycle, from decapping through final sizing and seating. If you're setting up or expanding a progressive or single-stage press system for these specific calibers, this is the component you need.

Lee Precision shell plates are engineered to tight tolerances so your brass seats squarely in the die station every time. That consistency translates to uniform rounds and reliable function downrange. The Breech Lock Pro system is built around strength and repeatability, making it a solid choice whether you're a volume reloader or someone who takes their handload quality seriously.

This is a caliber-specific component—it's cut for 500 S&W and 7.62x54R only. Before ordering, confirm your press model is compatible with Breech Lock Pro shell plates and that you don't already have #16 in your setup. It's one of those small parts that's easy to overlook but absolutely central to consistent reloading results.
