Lee 90045 vs Frankford M-Press: Reloading Press Comparison

Two names consistently surface when shooters start looking for a reliable, no-fuss single stage press: Lee Precision and Frankford Arsenal. The Lee Precision 90045, often called the Classic Cast, and the Frankford Arsenal M-Press represent two distinct philosophies in bench press design. This direct comparison cuts through the noise to give you the practical insights needed for your reloading setup.

Whether you’re focused on precision reloading for long-range accuracy or seeking a durable, straightforward press for learning the craft, the choice matters. Honestly speaking, both have earned their reputations, but they cater to slightly different priorities in the reloading process. Let’s break down their build, performance, and value.

Head-to-Head Overview: Lee 90045 vs Frankford M-Press

At first glance, these are both robust single stage presses built for longevity. The Lee 90045 is a classic O-frame design with a reputation for sheer strength, while the Frankford M-Press introduces a modern, guided approach with its parallel rod system. This fundamental difference in architecture influences everything from operation feel to spent primer management.

For beginners embarking on reloading for beginners, se core designs is key. The O-frame is a time-tested workhorse, whereas the guided system aims for enhanced alignment and stability. My honest take is that neither is inherently “better”; it’s about which system’s advantages align with your workflow.

Build Quality & Design Comparison

The Lee 90045 is built around a massive cast iron O-frame. This material choice is about brute force and dampening; cast iron absorbs vibration and provides a rock-solid foundation for sizing operations. It’s the definition of a classic bench press, with an emphasis on mechanical simplicity and press durability.

Conversely, the Frankford M-Press utilizes a heavy-duty die-cast construction. Its standout feature is the twin parallel guide rods that ensure the ram moves in a perfectly vertical plane. This design aims to eliminate any side-to-side play, which can be a critical factor for reloading press for accuracy. In my honest opinion, the M-Press’s guided system feels more “modern,” while the Lee feels more “industrial.”

Noise, Vibration, and

This is where we cover ground others often skip. The Lee’s cast iron frame naturally provides superior noise and vibration damping compared to most aluminum or die-cast frames. You’ll feel less “chatter” during tough resizing operations. The M-Press’s guided rods add stability but don’t necessarily dampen sound the same way.

Warranty and support are also part of the reloading press comparison. Lee Precision is known for strong customer support and readily available parts. Frankford Arsenal, as a larger brand, also offers support, but it’s wise to check the specific warranty terms at purchase. Both brands have generally positive reputations here.

Performance & Features: Priming, Leverage, and Operation

Performance boils down to leverage and primer handling. The Lee 90045 employs a compound linkage system. This design provides significant mechanical advantage, making it easier to size stubborn brass with less perceived effort on the lever. It’s a proven system that excels at the heavy lifting.

The Frankford M-Press focuses on smooth, aligned operation. The floating shell-holder plate is a clever feature, allowing the shell holder to self-center under the die for improved alignment. This can contribute to more consistent bullet seating and case sizing. Speaking honestly, for a beginner, this auto-alignment can be a forgiving feature that helps produce better ammo from the start.

The Critical Primer Handling Systems

Both presses address the messy issue of spent primer disposal. The Lee includes a primer catchera simple but effective chute that directs spent primers into a tube or container. It’s a functional, no-fuss solution that has worked for decades.

The Frankford Arsenal M-Press also features a spent primer catcher. The integration with its guided system means primers drop cleanly away from the working area.

Honest to goodness, efficient primer management keeps your bench clean and is a feature no shooter should overlook.

User Experience: Ergonomics and Ease of Use

Ergonomics can make or break a reloading session. The Lee 90045, with its compound linkage, offers a distinct leverage curve. The initial pull feels smooth, with power ramping up through the stroke. It’s a comfortable, efficient motion for high-volume case prep. The press is a dedicated tool, often requiring separate purchases for additional reloading accessories like case holders or mounting solutions.

The Frankford M-Press aims for a different feel. The parallel rods create a consistently smooth stroke from top to bottom. The quick-change die blocks are a significant usability boostswapping dies becomes a matter of seconds without constantly threading and unthreading. This is a huge plus for load development where you’re changing dies frequently. Its versatility, as noted in its features, means it “does a lot” within a single, integrated unit.

• Lee 90045 Feel: Powerful, mechanical, and direct. You feel the mechanical advantage.
• Frankford M-Press Feel: Smooth, guided, and streamlined. The focus is on precision and ease.

Regarding compatibility, both accept standard 7/8″-14 dies from any major manufacturer like RCBS, Hornady, or Lyman. This universal thread standard means your investment in quality dies from an official source like Hornady is safe with either press. You’re not locked into one brand’s ecosystem.

Verdict: Best Use Cases and Final Recommendation

So, which is better: the Lee 90045 or Frankford M-Press? The answer depends entirely on your reloading personality and goals.

Choose the Lee Precision 90045 Classic Cast if:
You value raw, proven durability and mechanical advantage above all. You don’t mind a more traditional setup and prioritize a rock-solid foundation for tough sizing operations. It’s an excellent choice for the reloader who wants a lifetime press for high-volume case preparation or full-length resizing. The question of durability of Lee Classic Cast vs M-Press often leans toward the Lee’s cast iron heritage.

Choose the Frankford Arsenal M-Press if:
You appreciate modern engineering and streamlined workflow. The quick-change die blocks and floating shell holder are major benefits for load development or those who switch calibers often. If you’re looking for a reloading press for beginners that incorporates thoughtful features to aid precision from the start, the M-Press is compelling. Its integrated approach to spent primer disposal and stability is well-executed. For more on Frankford’s ecosystem, see how their frankford case prep tools compare.

My Honest Assessment & Final Word

I honestly believe the Lee 90045 remains the undisputed champion for sheer, brute-force durability and simplicity. It’s a tool that will outlast most of us. However, the Frankford Arsenal M-Press makes a incredibly strong case for itself as a modern, feature-rich best single stage press contender that enhances the user experience.

For the beginner seeking an easier, more feature-integrated path to quality ammo, the M-Press might be the more satisfying choice. For the traditionalist or someone processing large batches of rifle brass, the Lee’s compound linkage and cast iron frame are hard to beat. To be completely honest, you can’t go wrong with either for building a solid reloading setup. It comes down to whether you prefer timeless mechanical leverage or modern guided precision.
