Description
The Mark 7 Universal Pistol Mechanical Powder Measure is made for reloaders who care about clean, consistent charges and want to get rid of the separate bench-mounted measure taking up real estate. It mounts right to your press, so the powder drop happens as part of your normal stroke instead of as a second step. That means less clutter and a faster rhythm when you're running through a big batch of 9mm, 45 ACP, or anything else on the handgun menu.
The headline number here is accuracy within plus or minus a tenth of a grain, which is the kind of consistency that keeps your velocities tight and your groups honest. A generous 5,000-grain hopper means you can load a long session without constantly topping off, and the integrated powder screen helps keep debris out of your charges. Inside, there's a powder baffle that keeps pressure on the metering chamber even as the hopper drains down, so your first drop and your five-hundredth drop land in the same spot.
What Makes the Mark 7 Powder Measure Tick
This is a case-activated unit with built-in compliance, so it works with slightly varying case lengths without throwing off your charge. The rotating barrel rides on sealed ball bearings with oil-impregnated bronze bushings on the sliding surfaces, which is why the cycle feels smooth and holds up under the constant vibration of a motor-driven press. It's CNC machined and built to run hard, whether you're cranking a manual progressive or letting an autodrive do the work.
Fitting the Mechanical Powder Measure to Your Setup
It's designed for Mark 7 Apex 10 and Evolution machines and plays nice with standard 7/8-14 threaded stations, so it can go on a variety of presses. Breakdown for cleaning is simple, and if you ever want to run rifle, converting over is a matter of swapping the drum and funnel with the appropriate conversion kit. For a high-volume pistol loader, it's one of those upgrades that pays you back every session in consistency and saved time.

Frequently Asked Questions
What presses does the Mark 7 Universal Pistol Mechanical Powder Measure work with?
It's designed for Mark 7 Apex 10 and Evolution machines and fits standard 7/8-14 threaded stations, so it can go on a variety of progressive presses. It handles both manual and motor-driven setups well because the bearings and build are made for constant cycling. If you're running an automated press, this measure holds its setting through the vibration.
Can I convert this pistol measure to load rifle calibers?
Yes. Switching from pistol to rifle is done by swapping the drum and the appropriate funnel using a separate Mark 7 conversion kit. The unit breaks down simply for both cleaning and the changeover, so you're not fighting it when you want to switch.
How accurate are the powder charges?
It meters within plus or minus a tenth of a grain, which is excellent for handgun loads where charges are small and consistency matters. A powder baffle keeps the metering chamber under steady pressure as the hopper empties, so your charges stay uniform from the first drop to the last.
How much powder does the hopper hold?
The hopper holds 5,000 grains, which is plenty for a long loading session without constant refilling. It also has an integrated screen to keep debris out of your powder, which helps protect the consistency of every drop.
