Pricing Analysis

The Redding 3 Powder Measure with Handgun Metering Chamber occupies the premium tier of the manual measure market. While general-purpose measures are often cheaper, the specialized handgun chamber included here is machined to tighter tolerances for lower volume drops. In the 2024-2026 market, shooters often choose this model to avoid the “slop” found in universal measures when trying to drop very light charges of powders like Alliant Bullseye. The investment is justified by the unit’s “generational” durability, as a Redding 3 Powder Measure with Handgun Metering Chamber is designed to outlast several electronic dispensers.


Build Quality, Materials, and Ergonomics

The defining characteristic of the Redding 3 Powder Measure with Handgun Metering Chamber is its heavy cast iron housing. Unlike aluminum or plastic measures, the mass of the cast iron frame in the Redding 3 Powder Measure with Handgun Metering Chamber dampens vibration and resists static electricity, both of which are common culprits for inconsistent powder throws.

Ergonomics and Mechanical Advantage

The operating handle is balanced to provide a smooth, rhythmic “feel.” The handgun metering chamber is designed to drop charges between 0 and 10 grains, though it can go higher depending on powder density. This smaller diameter metering cavity means that the adjustment screw has a higher resolution; a single turn of the screw on the Redding 3 Powder Measure with Handgun Metering Chamber results in a smaller change in volume than it would on a rifle measure, allowing for extremely fine-tuned loads for 9mm Luger or 38 Special.


Comprehensive Setup, Calibration, and Operation

To maximize the performance of your Redding 3 Powder Measure with Handgun Metering Chamber, follow this professional setup guide:

  1. Mounting: The Redding 3 Powder Measure with Handgun Metering Chamber features a 7/8-14 thread. It should be mounted to a sturdy bench stand or a press-mounted bracket.
  2. Degreasing: Before the first use, disassemble the metering unit and clean the steel drum of the Redding 3 Powder Measure with Handgun Metering Chamber with a residue-free cleaner to remove anti-corrosion oils.
  3. Hopper Setup: Fill the hopper at least 1/2 full of a handgun powder such as Winchester 231 or Hodgdon HP-38.
  4. Initial Settling: Throw 10-15 “throwaway” charges. This coats the internal surfaces with graphite and settles the powder column for more consistent volume in the Redding 3 Powder Measure with Handgun Metering Chamber.
  5. Calibration: Adjust the metering screw until you reach your target weight, verifying every few throws on a scale like the RCBS M500 Balance Beam Mechanical Powder Scale.

Maintenance

The Redding 3 Powder Measure with Handgun Metering Chamber is largely self-maintaining if kept in a dry environment. Periodically wipe the exterior with a light oil to prevent rust on the cast iron, but keep the interior dry. If the drum movement on the Redding 3 Powder Measure with Handgun Metering Chamber feels gritty, disassemble and clean with a dry brush; never use liquid lubricants inside the measure.

Redding offers a clear upgrade path for those using the Redding 3 Powder Measure with Handgun Metering Chamber:


Competitive Market Analysis

The Redding 3 Powder Measure with Handgun Metering Chamber competes with other high-end manual handgun measures.

1. RCBS Uniflow Powder Measure 3

The RCBS Uniflow Powder Measure 3 is a direct rival. While the RCBS is a fantastic all-arounder, the Redding 3 Powder Measure with Handgun Metering Chamber is often preferred by those who want a measure dedicated strictly to the smaller volumetric requirements of pistol propellants.

2. Hornady Lock-N-Load Powder Measure

The Hornady Lock-N-Load Powder Measure offers a quick-change insert system. While the Hornady is more convenient for multi-caliber benches, the Redding 3 Powder Measure with Handgun Metering Chamber provides a more solid, cast iron feel that many traditionalists prefer.

3. Lyman Brass Smith Powder Measure

The Lyman Brass Smith Powder Measure is a solid mid-range choice. However, the Redding 3 Powder Measure with Handgun Metering Chamber usually features tighter tolerances in its handgun metering unit, leading to better consistency with flake powders like Alliant Unique.

4. Lee Perfect Powder Measure

The Lee Perfect Powder Measure is the budget champion. It works surprisingly well, but it lacks the weight, the cast iron durability, and the “heirloom” build quality of the Redding 3 Powder Measure with Handgun Metering Chamber.

Real-World Feedback & Troubleshooting

Users of the Redding 3 Powder Measure with Handgun Metering Chamber frequently cite its “clocks-like” precision.

Pros

  • Extremely high resolution for small charges (3-6 grains).
  • The cast iron body is a natural defense against static build-up.
  • Heavy construction makes for a very stable bench presence.

Cons

  • Changing to rifle-sized charges requires purchasing a separate metering unit.
  • Lack of a micrometer on the base model makes recording exact settings more manual.
  • Heavier than most other measures in its class.

Troubleshooting

  1. Leaking with Ball Powders: If using very fine ball powder like Accurate No. 2, ensure the side tension screw on the Redding 3 Powder Measure with Handgun Metering Chamber is tight enough to close any gaps between the drum and the frame.
  2. Bridging with Flake Powders: Flake powders like Alliant Red Dot can occasionally bridge. A consistent “double-tap” at the top of the stroke is the expert workaround.
  3. Static Issues: If powder is jumping in the hopper, wipe the clear reservoir of the Redding 3 Powder Measure with Handgun Metering Chamber with a dryer sheet.

FAQ

Q: Can I drop 50 grains of powder with the Redding 3 Powder Measure with Handgun Metering Chamber?

A: No, the handgun metering chamber is too small for large rifle charges. You would need the universal metering chamber for that.

Q: Is the metering unit made of stainless steel?

A: It is made of polished, hardened steel, which is very durable but should be kept dry to prevent rust.

Q: Does it fit the Redding T-7 Turret press?

A: Yes, it uses standard 7/8-14 threads and fits most presses and stands.

Q: Is it compatible with Hodgdon Titegroup?

A: Yes, it is exceptionally accurate with Hodgdon Titegroup.

Q: Can I upgrade this to a micrometer unit?

A: Yes, Redding sells micrometer metering units that are compatible with the Redding 3 Powder Measure with Handgun Metering Chamber.

Q: Does it come with a powder baffle?

A: It typically does not include a baffle; adding one is a common and effective upgrade.

Q: How do I empty the measure?

A: Most users simply remove the measure from the stand and pour it back into the original canister.

Q: Is it safe for 45 ACP?

A: It is ideal for 45 ACP and all other standard pistol calibers.


Conclusion & Expert Verdict

The Redding 3 Powder Measure with Handgun Metering Chamber is a purpose-built tool for the handgun reloader who refuses to compromise on consistency. While it lacks the universal appeal of larger-bore measures, its specialization is its greatest strength, providing a level of control over small powder volumes that is difficult to replicate with all-purpose gear. For the competitive bullseye or action pistol shooter, the Redding 3 Powder Measure with Handgun Metering Chamber is a lifetime investment in accuracy.

Expert Pro Tip: For the absolute best results with the Redding 3 Powder Measure with Handgun Metering Chamber, install a powder baffle halfway up the hopper. This ensures the weight of the powder column on the metering drum remains the same, regardless of whether the hopper is full or nearly empty.
