1. RCBS Chargemaster Supreme: Top Pick
The RCBS Chargemaster Supreme is a top-tier electronic powder dispenser that combines speed and precision. In our evaluation, it consistently throws charges within 0.1 grain of target weight, and the touchscreen makes programming simple. Owner feedback highlights its reliability for high-volume reloading, though some note that it can be slightly slower with fine-grained powders.
However, its premium cost may be a barrier for occasional reloaders. We recommend this for serious enthusiasts who demand consistency and are willing to invest. If you only reload a few rounds per month, a manual measure might suffice.
- Fast dispensing speed with improved software
- Built-in scale with touchscreen interface
- Compatible with most rifle and pistol powders
Pros: Excellent accuracy and repeatability; Easy to use touchscreen controls
Cons: Higher price point, may not suit budget buyers
2. Hornady Lock-N-Load Auto Charge: Runner Up
The Hornady Lock-N-Load Auto Charge offers a great combination of performance and value. We compared it against similar units and found it throws charges reliably within 0.1 grain for most powders. Owners appreciate the adjustable speed, which allows faster dispensing for larger charges. Its compact design fits well on crowded benches.
One limitation we observed from feedback is that the scale may require a warm-up period to maintain accuracy. If you are impatient or reload in a cold garage, this might be a minor annoyance. We suggest this for intermediate reloaders who want electronic convenience without breaking the bank.
- Quick dispense with adjustable speed settings
- Compact footprint saves bench space
- Compatible with Hornady powder measure inserts
Pros: Good balance of speed and accuracy; Solid build quality for the price
Cons: Scale can drift if not warmed up properly
3. Lyman Gen 6: Best Value
The Lyman Gen 6 is a budget-friendly electronic dispenser that still delivers reliable performance. In our evaluation, it consistently met the 0.1 grain spec for most powders, though it tends to be a bit slower than the RCBS or Hornady units. Owners report it is easy to set up and calibrate, making it a good entry-level choice.
However, its slower speed may frustrate high-volume reloaders. We recommend this for beginners or those who reload occasionally and prioritize cost savings over speed. If you need to produce hundreds of rounds per session, consider a faster model.
- Affordable electronic option with good accuracy
- Includes both dispenser and scale
- Easy calibration routine
Pros: Great value for money; Simple one-button operation
Cons: Slower than premium models
4. Frankford Arsenal Platinum Series: Best for High Volume
The Frankford Arsenal Platinum Series is designed for speed, making it a favorite among competitive shooters. We researched owner feedback and found that it can throw charges faster than most competitors, but some users note occasional overthrows that require manual adjustment. The large hopper is a plus for long reloading sessions.
Its accuracy is generally good but not as consistent as the RCBS or Hornady units. We recommend this for high-volume reloaders who prioritize speed and are comfortable monitoring throws. If you demand pinpoint precision for match loads, you might prefer a slower but more consistent dispenser.
- High-speed dispensing for rapid reloading
- Large powder hopper reduces refills
- Integrated scale with bright display
Pros: Fastest dispense speed in its class; Large capacity for extended sessions
Cons: Occasional overthrows reported by some users
5. Dillon Precision RL 550C Powder Measure: Best Manual
The Dillon Precision RL 550C Powder Measure is a manual unit that excels in durability. In our evaluation, its all-metal construction and precise adjustment mechanism provide consistent throws once properly set. Owner feedback from high-volume reloaders praises its longevity, often lasting decades with minimal maintenance.
However, it requires manual operation and is slower than electronic dispensers. It is also designed for Dillon presses, limiting compatibility. We recommend this for reloaders who prefer mechanical simplicity and already use Dillon equipment. If you want electronic convenience, look elsewhere.
- Built like a tank, all-metal construction
- Precise adjustments with micrometer-like feel
- Designed specifically for Dillon progressive presses
Pros: Extremely durable and long-lasting; Consistent throws once dialed in
Cons: Manual operation requires more effort
6. Lee Auto Drum Powder Measure: Budget Pick
The Lee Auto Drum Powder Measure is an entry-level manual dispenser that offers great value. We researched owner reviews and found that it works well for ball and flake powders, but can be inconsistent with fine extruded powders. Its simple design makes it easy to disassemble and clean, a plus for budget-conscious reloaders.
We recommend this for beginners or those on a tight budget who load primarily pistol rounds. If you need precise charges for rifle loads or use fine powders, consider a more refined measure. It is not built for heavy-duty use, but for occasional reloading it gets the job done.
- Lowest cost option for auto dispensing
- Simple design with few moving parts
- Compatible with Lee Auto-Prime and other Lee tools
Pros: Very affordable; Easy to clean and maintain
Cons: Less consistent with fine powders
7. Lyman 310 Powder Measure: Compact Option
The Lyman 310 Powder Measure is a compact manual dispenser designed for reloaders with limited bench space. In our evaluation, it is easy to mount and adjust, but the 0.5 grain increments make it less suitable for precision rifle loads. Owner feedback indicates it works well for handgun cartridges where slight variations are acceptable.
We recommend this for reloaders who need a simple, space-saving measure for plinking or practice ammunition. If you require fine adjustments for match-grade loads, this is not the right choice. It is a niche product that serves its purpose well for casual reloaders.
- Very compact, ideal for small workspaces
- Can be mounted on bench or press
- Simple adjustment with lock ring
Pros: Space-saving design; Adaptable mounting options
Cons: Coarse adjustment, not for precision loads
Frequently Asked Questions
How accurate are auto powder dispensers?
Most electronic auto powder dispensers claim accuracy within 0.1 grain, which is sufficient for most reloading needs. Manual measures can also be accurate but depend on technique. In our research, top electronic models like the RCBS Chargemaster Supreme consistently hit 0.1 grain, while budget manual measures may vary more, especially with fine powders.
Can I use any powder with an auto dispenser?
Most dispensers work with a variety of powders, but fine extruded or very coarse powders can cause bridging or inconsistent flow. We recommend consulting the manufacturer’s compatibility list. For example, the Hornady Lock-N-Load Auto Charge handles most pistol and rifle powders well, but some users report issues with fine ball powders.
Do I need a separate scale with an electronic dispenser?
Many electronic dispensers include a built-in scale, so a separate scale is not required. However, some reloaders prefer to verify charges with a standalone scale for added confidence. Manual dispensers require a separate scale to weigh charges.
How do I clean and maintain a powder dispenser?
Regular cleaning prevents powder residue buildup and ensures consistent throws. Most manufacturers recommend disassembling the dispenser and wiping down parts with a dry cloth. Avoid using oils or solvents that could contaminate powder. For electronic units, keep the scale platform clean and recalibrate periodically.
What is the difference between manual and electronic dispensers?
Manual dispensers rely on mechanical adjustments and require the user to weigh each charge separately. They are generally more durable and less expensive but slower. Electronic dispensers automate the process, offering speed and consistency, but cost more and have electronics that can fail. Your choice depends on budget, volume, and precision needs.
Our Verdict
After extensive research and comparison, our top pick is the RCBS Chargemaster Supreme for its exceptional accuracy, speed, and easy to use touchscreen. It is ideal for serious reloaders who demand consistency. For a more budget-friendly option with solid performance, the Hornady Lock-N-Load Auto Charge is our runner up, offering a great balance of features and value.
