Case trimming is the chore that slows every high-volume reloader down, and the Mark 7 Power Trim Xpress was built to fix that. This is a press-mounted electric trimmer that bolts right onto your setup and runs off an industrial-grade variable speed DC motor, the same kind of workhorse motor you'll find on CNC equipment. It muscles through standard trim jobs and heavier cartridge conversions without breaking a sweat, and the variable speed lets you dial it in for the brass you're working.
The biggest win here is the footprint. The slim motor design means the trimmer only takes up one die station on a progressive press, where a lot of competing setups hog two or three. That matters when you've got a full toolhead and every station counts. It works on most progressive, automated, turret, and single station presses, so it fits whether you're running a Dillon, a Mark 7 autodrive, or a simple single-stage for small-batch work.
The Power Trim Xpress uses standard trim dies, so you're not locked into a proprietary ecosystem. A 1-1/2 inch vacuum manifold is built in to pull chips and shavings away as you trim, which keeps your bench and your brass clean. The cutter is a long-lasting replaceable carbide end mill, so when it finally dulls after a lot of use you just swap it rather than scrap the whole unit. For folks converting .223 brass into .300 Blackout, this thing trims and forms the case in a single stroke, which is a huge time-saver if you're building Blackout in any real volume.
Keep in mind the trimmer requires the appropriate trim die for your caliber, and those are sold separately. It's normal for the motor body to run warm during long sessions since that's just the nature of a hard-working DC motor pushing through a big pile of brass.
No, the trimmer does not include a trim die or extended shellholder. You'll need to buy the appropriate standard trim die for each caliber you plan to trim. The good news is it accepts standard trim dies, so you're not stuck with proprietary parts.
It mounts to most progressive, automated, turret, and single station presses. Reloaders run it on everything from Mark 7 autodrive machines and Dillon progressives to a simple single-stage press for smaller batches. It only takes up one die station on a progressive, which keeps your toolhead free for other operations.
Yes, and that's one of its standout tricks. It trims and case forms .300 Blackout from .223 brass in a single stroke, which makes it a go-to for anyone building Blackout in volume. You will need the correct .300 Blackout trim die to do it.
Yes. The motor body running warm during extended trimming sessions is normal and expected with a hard-working DC motor. It's just the nature of pushing through a large volume of brass, so there's no cause for concern during long runs.
