Mark 7 Universal Rifle Mechanical Powder Measure

The Mark 7 Universal Rifle Mechanical Powder Measure is a press-mounted solution designed for reloaders who want to consolidate their bench setup without sacrificing accuracy or efficiency. Instead of dedicating space to a separate powder measure, this unit mounts directly to your existing press—whether you're running a single-stage, turret, or progressive system—and handles rifle cartridge reloading with consistent, repeatable results. If you're building precision rifle ammunition or simply looking to streamline your loading sequence, a press-mounted measure cuts setup time and frees up real estate on an already crowded workbench.

Mark 7 engineered this measure around the details that matter to serious reloaders. The charge output holds accuracy within ±0.1 grain, which is tight enough for hunting and match loads alike. The 5,000-grain hopper means fewer refills during a loading session, and the integrated powder screen keeps dust and debris out of your charges. A powder baffle inside the hopper promotes consistent metering, while case-actuated operation with built-in compliance adapts to varying case lengths—no trimming required. The rotating barrel rides on deep-groove ball bearings and bronze bushings, both designed for smooth, wear-resistant operation over years of use.

Durability is built in: all stainless-steel internals resist corrosion and wear, and the oil-impregnated bronze bushings on sliding surfaces keep the action smooth. When it's time to clean or switch between rifle and pistol loads, simple disassembly gets you there without special tools or frustration. This is the kind of workhorse engineering Mark 7 has built a reputation on—functional, reliable, and purpose-built for reloaders who demand accuracy and repeatability.
