Product Description The RCBS UPM-3 Competition Powder Measure is built for reloaders who demand consistent, repeatable powder charges. Based on the proven Uniflow design, it adds a powder baffle to stabilize powder flow and a micrometer adjustment screw to fine-tune and record settings for future load sessions. The ambidextrous handle can be configured for right- or left-hand operation, and the threaded hopper design supports easy removal and cleanup. For best results, use this powder measure alongside an accurate powder scale to set and periodically verify charges. Do not use this powder measure with black powder.
