    Factory Second

    The "O" frame press by design is the strongest and by far the most popular style press. The larger than average 4" opening allows for maximum hand clearance. The spent primer catcher is positive and allows you to route the spent primers directly to the trash can. Priming is a dream with the Lee Lever Prime System. Best of all, it includes the Breech Lock Quick Change die system. Change dies instantly with a twist of the wrist, and you never have to re-adjust your die.

    Other features include all steel linkage with adjustable length lever. This same press costs you over twice as much from other manufacturers, and that's without all of the Challenger's features. Press includes one Breech Lock quick change bushing.

    Frame is cast out of aluminum.

    Spline Drive Bushings

    Spline Drive Bushings

    New, easy grip splined drive surface allows easy, accurate and fast die installation in your press. Reloading dies are confusingly similar looking, so we anodized and colored the bushings so you can “color code” your dies for quick positive identification. No need for lock rings on your dies with these quick-change bushings. Simply lightly tighten the clamp screw, and split collar will put a vise lock on your die. Loosen the screw, and the die will spin freely. Once set you’ll never lose position.

    They look so good and work so well, you’ll want them for all your dies.

    For even easier installation, we have a handy lock ring wrench. Works with Lee Spline drive lock rings and Breech lock bushings.

    Customer Product Review

    I just wanted to say that recently I purchased a Lee Challenger press and dies for several of my older military rifles. Along with this I purchased dippers and scales and several more items including "Modern Reloading 2nd Edition Richard Lee" manual.

    This was my first experience with reloading and I can honestly say that you guys build a very good quality product. I read your Modern Reloading manual and enjoyed every page. It's nice to see a company take pride in their product as you guys do. Using your products make it very enjoyable to reload, and something I'll do from now on and pass it on to my kids.

    My first reloads through my Springfield 1903A3, using your equipment, I was able to consistently shoot 1" groups @ 100yds with this old rifle. Thank you for making such a good product and producing such a good reloading manual to read and follow. You have made a lifetime customer out of me.

    Thank you and Take Care, Donald B. - Talking Rock, GA - March 18, 2017
