Description
Lee Precision built its reputation on presses that just work, and the Challenger III is the third generation of the one that started it all. This 40th Anniversary Pack celebrates four decades of the design by pairing the press with a free .223 Rem Breech Lock 3-die set, giving you a ready-to-load package for one of the most popular rifle cartridges around. The press uses the time-tested "O" frame layout, which is the strongest and most popular style for a reason, and the larger than average 4-inch opening gives you plenty of hand clearance when you're seating bullets or working longer cases.
What Makes the Challenger III Worth the Upgrade
The big story on this generation is comfort. Lee added an ergonomically formed lever that cuts out the stooping at the bottom of the stroke, so long reloading sessions are a lot easier on your back and shoulders. The priming position has been moved up front where the action is, and the Lee Lever Prime System lets you handle priming right on the press. Through-ram primer disposal sends spent primers down into a collection tube, which keeps the grime off the frame and ram and your bench a whole lot cleaner.
The Breech Lock Quick-Change Advantage
The Breech Lock system is what sets this apart from a standard threaded press. Each die locks into a bushing, so once you've set your depth you can pop dies in and out with a quarter twist and never lose your adjustment. That means moving from sizing to seating takes seconds instead of re-dialing everything every time.
Loading .223 Rem Out of the Box
The included .223 Rem set covers the full job: a Full Length Sizing Die, an Easy Adjust Dead Length Bullet Seating Die, a Factory Crimp Die, plus colored Smart Lock bushings for quick die ID, a universal shell holder, a powder dipper, and load data. It's a solid foundation for anyone getting into rifle reloading or adding a dedicated .223 setup to the bench.

Frequently Asked Questions
What comes in the Lee Challenger III 40th Anniversary Pack?
You get the Challenger III single-stage press along with a free .223 Rem Breech Lock 3-die set. The die set includes a Full Length Sizing Die, an Easy Adjust Dead Length Bullet Seating Die, and a Factory Crimp Die, plus colored Smart Lock bushings, a universal shell holder, a powder dipper, and load data. It's basically a complete starting point for loading .223.
Can the Challenger III load 5.56 NATO as well as .223 Rem?
Yes, the included .223 Rem die set can be used to load 5.56 NATO (5.56x45mm) brass. You'll want to follow published load data specific to 5.56 NATO, which you can get from your preferred powder manufacturer. The press itself handles both without any changes.
What is the Breech Lock system on this press?
The Breech Lock is Lee's quick-change die system. Each die threads into a bushing that locks into the press with a short twist, so once you dial in your settings you can swap dies in and out without re-adjusting. It makes moving between sizing, seating, and crimping fast and repeatable.
Is this a good press for someone new to reloading?
It's a strong choice for beginners. The single-stage O-frame design is simple and forgiving, which is exactly how most folks learn the fundamentals, and the included dies and load data mean you're not hunting for extra parts to get going. The ergonomic lever and on-press priming also make longer sessions more comfortable as you build experience.
