The RCBS Uniflow Powder Measure Case Activated Linkage Kit transforms your single-stage powder measure into an automated progressive press accessory. If you're running a four or five-station progressive press and want the speed and consistency of case-activated powder dispensing, this kit mechanically links your Uniflow measure to your press's indexing cycle—no manual throws needed between rounds. It's the kind of upgrade that turns a reloading session from tedious to genuinely efficient, especially when you're burning through large batches of rifle or pistol ammunition.
The kit ships with three powder bushings that cover the vast majority of handloads: a Small Rifle bushing for cartridges from .22 through .270, a Large Rifle bushing for 7mm through .45, and a Pistol bushing spanning .32 through .45. Each bushing is engineered to minimize powder scatter around the case mouth—a small detail that keeps your reloading bench cleaner and reduces wasted powder over the course of a season. The system adjusts fully for case length variation, so you're not locked into a single cartridge's dimensions.
Keep in mind: the Uniflow Powder Measure itself is sold separately. You'll be installing this linkage kit onto a measure you already own or plan to purchase. The kit works whether your Uniflow has the standard Measuring Screw or an optional Micrometer Adjustment Screw, so it's flexible depending on how you've outfitted your measure.

The case-activated linkage is designed for four or five-station progressive presses. Confirm your press falls into that category before purchasing.
No—this is the linkage kit only. You'll need to purchase the Uniflow Powder Measure separately. The kit will install onto your existing Uniflow or one you source yourself.
The three bushings cover Small Rifle (.22–.270), Large Rifle (7mm–.45), and Pistol (.32–.45). For most common hunting and handgun cartridges, you're covered out of the box.
Yes. The linkage kit is compatible with Uniflow measures equipped with either the standard Measuring Screw or the optional Micrometer Adjustment Screw.
