Two tools sit on your reloading bench, each serving a fundamentally different purpose. One measures the very heart of your cartridge’s power, while the other shapes its form. The WISHSOM RS-1500 Digital Reloading Scale and the Lee Precision 92139 40th Anniversary Die Set represent two distinct pillars of the handloading process. Comparing them isn’t about declaring a single winner, but about understanding how each contributes to the final goal: safe, consistent, and accurate ammunition.
This analysis breaks down what each product brings to your reloading bench setup. We’ll examine their core functions, their impact on your workflow, and where their value truly lies. From the granularity of a powder charge to the smooth operation of a die set, every detail matters.
Head-to-Head Product Overview
At first glance, these tools couldn’t be more different. The WISHSOM RS-1500 is a modern electronic instrument focused on measurement. The Lee Precision 92139 is a mechanical, durable toolset focused on forming and assembly. One deals in digital precision, the other in mechanical precision.

Honestly speaking, you can’t have one without the other in a complete reloading workflow. The scale ensures your powder measure is throwing the correct charge, while the dies ensure your brass and bullet are assembled correctly. They are complementary, not competitive.
Accuracy & Performance Deep Dive
This is where the core missions of these tools diverge completely. For the WISHSOM RS-1500, accuracy is about stable, repeatable electronic measurement. For the Lee dies, it’s about precise mechanical tolerances and repeatable adjustments.
Scale Precision: The Digital Realm
The WISHSOM scale offers a 0.1 grain resolution, which is a solid standard for most rifle and pistol cartridge reloading. The included 50g calibration weight is crucial for maintaining long-term accuracy. My honest assessment is that a scale’s true performance is often defined by factors beyond its specs. Scale warm-up time and environmental factors like drafts or bench vibration can significantly impact readings, something many reviews overlook. A compact scale like this can be more susceptible to these issues if not placed on a stable surface.
When considering the best budget digital scale for reloading, the RS-1500’s package is compelling. The tare function and backlit display are practical for low-light bench conditions. Battery life and the auto-shutoff are practical considerations for your reloading bench setup, preventing dead batteries mid-session. To be completely honest, learning how to calibrate WISHSOM RS-1500 for precise charges regularly is as important as the scale’s initial quality.
Die Precision: The Mechanical Realm
The Lee Precision 92139 die set achieves accuracy through consistency. The Breech Lock system means that once a die is perfectly adjusted, you can remove and re-install it without losing that setting. This is a huge time-saver and directly contributes to reloading consistency across multiple loading sessions. The die performs the critical case mouth expansion and bullet seating operations with uniformity.
The dies are designed for the specific .223 Remington cartridge, ensuring proper thread compatibility with standard presses and correct dimensions for the case neck. From my honest perspective, the mechanical precision of a die set like this is proven over hundreds of cycles, not in a single measurement. Its reliability is in its simplicity and robust construction.
Features & Usability Comparison
Usability defines your experience at the reloading bench. A frustrating tool slows you down and can introduce errors. Let’s break down how these products function in real use.
WISHSOM RS-1500: Setup and Daily Use
- Compact & Portable: Its small footprint (4.72 x 2.4 inches) saves precious bench space.
- Simple Operation: Tare function and clear LCD make weighing charges straightforward.
- Versatility: It can double as a scale for weighing bullets, small parts, or even arrows.
- Dependency: Requires batteries and is sensitive to its environment. A draft shield might be a necessary add-on for some.
Lee Precision 92139 Dies: Integration into Your Workflow
- Breech Lock Quick Change: This is the standout feature. Changing dies “instantly with a twist of the wrist” streamlines the process immensely when switching operations.
- Complete Three-Die Set: Covers the full range needed for .223 Remington: sizing/depriming, case mouth expansion, and bullet seating.
- Press Compatibility: Designed to work with the Challenger press and other standard presses, a key point of thread compatibility.
I honestly believe the Lee die set’s usability shines in a progressive or turret press setup where quick changes are paramount. The WISHSOM scale’s usability is about providing a reliable, no-fuss measurement node in your process.

Value Analysis: Price vs. Performance
Value in reloading equipment isn’t just about the lowest price. It’s about reliability, longevity, and the confidence it gives you in your ammunition. A scale that drifts or a die that scratches cases costs more in the long run, regardless of its initial cost.
The WISHSOM RS-1500 positions itself as a value-oriented digital scale. It includes the essential calibration weight and offers a good range of features for its class. When you’re building your first reloading bench setup or need a backup scale, it represents a low-risk entry point. Speaking honestly, its value is tied to its consistency. If it holds calibration and resists environmental interference, it’s a great buy. If it doesn’t, it’s a paperweight.
The Lee Precision 92139 40th Anniversary set carries the value proposition of a trusted brand known for affordable, functional tools. The Breech Lock system adds tangible value The value here is in decades of design refinement offered at an accessible price point. You’re paying for proven function and a system that works seamlessly with other Lee equipment, like the press discussed in our analysis of precision turret presses.
My honest take is that both products aim for the “smart budget” segment. They aren’t the absolute cheapest options, nor are they the high-end luxury choices. They attempt to deliver core reliability without superfluous features, which for many reloaders is the sweet spot.
Final Verdict & Recommendation
So, which one should you buy? That’s the wrong question. The right question is: which one do you need based on the gap in your current setup?
You need the WISHSOM RS-1500 Digital Scale if:
You are entering the world of metallic cartridge reloading and need your first scale. You want a digital readout for charge weights. You need a compact, battery-powered scale for a portable bench or as a secondary check scale. Your primary concern is monitoring your powder measure‘s output for charge weight consistency.
You need the Lee Precision 92139 Die Set if:
You are loading .223 Remington/5.56 NATO ammunition. You own or are considering a press that uses the Breech Lock system (like the Lee Challenger). You value speed and convenience in switching between reloading steps. You want a straightforward, no-nonsense die set from a reputable manufacturer.
From my honest perspective, these two tools are a solid foundation for a new .223 reloader. The scale manages the explosive variable, while the dies manage the mechanical assembly. They address different but equally critical aspects of safety and performance. For authoritative information on reloading processes and safety, always consult an official source or manufacturer guide.
In the end, the best equipment is the equipment you use correctly and consistently. Whether you’re weighing a charge to the tenth of a grain or seating a bullet to the perfect depth, the focus and care you apply matter most. That’s the true Honest Opinion from the bench. Start with solid, purpose-built tools like these, learn their nuances, and your handloading equipment will reward you with the satisfaction of crafting your own accurate ammunition.
