Here’s the thing—at $20.48, this isn’t a competition-grade precision measure for smokeless pistol loads. It’s a purpose-built tool for its niche. The mechanism is straightforward: you adjust the cylindrical metering chamber by rotating it to increase or decrease the internal volume, which correlates to your powder charge. You then fill the chamber, give it a light tap to settle the granules, and dispense. It’s about consistency within a specific load, not micro-gram precision. The build uses a mix of materials to keep cost and weight down, making it a practical field or bench accessory. For reference, its total length is roughly 6 inches, and it weighs only a few ounces, so it won’t bog down your shooting bag.

Who This Powder Measure Is For

This tool is ideal for the muzzleloader hunter or shooter who needs a faster, more consistent method than a loose powder flask but doesn’t want the complexity or cost of a digital scale and trickler setup. It’s for the budget-conscious traditional shooter, the weekend black powder enthusiast, or someone adding a basic reloading station for cartridges like .45-70 Government using black powder. If you’re shooting a Thompson Center Hawken, Renegade, or a modern CVA Wolf, this measure fits the workflow perfectly. It’s also a solid backup for more experienced reloaders who want a dedicated measure for their black powder loads.

Pros & Cons: The Practical Tradeoffs

Pros: The price is the biggest win—it’s hard to find a dedicated measure at this point. It’s simple to use and easy to clean, which is crucial with corrosive black powder residues. It provides much better consistency than free-pouring from a flask, which directly impacts accuracy. No gunsmithing required; you just start using it.

Cons: It’s volumetric, so charge weight can vary slightly with different powder granulations or how you settle it. It’s not meant for modern smokeless powders used in high-pressure cartridges. The adjustability isn’t micro-fine, so it’s better for common charge increments. That said, for its intended use, these are acceptable trade-offs for the cost.

Frequently Asked Questions

Q: Can I use this with modern smokeless powder for my .308 Winchester?

A: We do not recommend it. This measure is designed for the larger, less dense granules of black powder and its substitutes. Smokeless powders are far more energy-dense and require precise weight measurement, not volume, for safe reloading.

Q: How do I calibrate or set the charge?

A: You’ll need a powder scale. Set your desired charge weight on the scale, then adjust the measure’s chamber until it throws that weight consistently. Mark the setting for future use. Remember, always verify by weight for safety.

Q: Is it compatible with all powder flasks?

A: It works with most standard black powder flasks and horns that have a removable spout. The threaded end is a common size. If your flask has a fixed spout, you may need to pour powder into the measure’s funnel top instead.

When you stack up the cost against the convenience it adds—moving from guessing to repeatable throws—the Thompson Center Field Powder Measure delivers clear bang-for-your-buck. It’s a single-task tool that does that task reliably without complicating the simple pleasure of black powder shooting. This product is available at firearms-missouri.com for Missouri residents and nationwide where compliant. If you’re setting up for muzzleloader season or rounding out your traditional shooting kit, this measure is a logical, low-cost addition.
