REDDING · 3BR · MICROMETER DOSING CHAMBERS
Prepare two charge ranges on the 3BR precisely and reproducibly
The interchangeable chambers complement an existing REDDING Match-Grade 3BR powder measure. Universal covers approximately 5–100 Grain, Handgun the fine range up to about 10 Grain.
Purchase check: exclusively 3BR, choose chamber by charge range


Honest assessment
The micrometer scale helps to find documented starting values again but is not a weight indication. Every new setting, every powder lot and every chamber must be checked on a suitable scale.



Fits well if …
you already own a REDDING Match-Grade 3BR
you want to prepare recurring large or small charge ranges
you document micrometer values and check every throw gravimetrically



Fits less if …
you use a BR-30, classic Model 3 or third-party powder measure
you expect a complete powder measure
you want to adopt a scale value unchecked as actual powder weight




Practical features and benefits


Universal 5–100 Grain Wide mechanical range for larger dosing quantities.

Handgun 0–10 Grain Finer adjustment reserve for small charges.

Quick chamber change Supports prepared, recurring workflows.

Micrometer adjustment Makes it easier to approach documented starting positions.
