- Made by Lee Precision
The Lee 1.25 Inch-12 Breech Lock Update Kit converts a standard single-stage reloading press with a 1 1/4"-12 threaded die station into a Breech Lock press, letting you use Lee's quick-change bushing system instead of screwing dies in and out by hand. The kit fits presses including the Lee Classic Cast, Hornady Iron and Lock-N-Load, RCBS Rock Chucker Supreme, and Redding Big Boss and 700 Ultramag, as well as other makes sharing the same 1 1/4"-12 thread — worth checking your press's removable bushing size before ordering. In the box you get the breech lock adapter itself, a spline drive lock-ring eliminator, and a lock-ring wrench, everything needed to fit the update with no extra parts required. Once installed, swapping between dies on a Breech Lock bushing is a matter of a quarter-turn rather than resetting the die's lock ring each time, which keeps your seating and sizing settings consistent from one reloading session to the next. A straightforward, well-priced way to bring an older press up to Lee's current bushing standard without replacing the press itself.
