Description
The 25 GT has earned its spot on the firing line with the long-range crowd, and it's a cartridge that lives or dies by the quality of your handloads. This RCBS Matchmaster Competition Full Length Bushing Die Set is a two-die package built to do that job right, with a full-length bushing sizer and a micrometer seater die working together to turn good brass into match ammo.
What Sets the Matchmaster 25 GT Sizing Die Apart
The full-length sizer brings your cases back to spec and de-primes in one pass, but the real story is the interchangeable neck bushing system. Instead of overworking your brass with a fixed neck, you drop in the bushing diameter that gives you the exact neck tension you want. That approach has been a benchrest and long-range staple for years because it keeps the brass working to a minimum, which stretches case life and pays off over a season of loading. Keep in mind the neck bushings are sold separately, so grab the right size for your brass before your first session. RCBS also builds these with a titanium carbo nitride expander to cut down on brass buildup and give you smoother case extraction.
Dialing In the Matchmaster Seater Die
The seater is where a lot of accuracy is won or lost, and this one is set up for repeatability. The oversized micrometer knob has big, easy-to-read hash marks so you can dial in a thousandth of an inch and get exactly that. RCBS's loading window lets you drop the bullet in and run the press without balancing it on the case mouth, and the internal sleeve holds everything in alignment for concentric seating you can count on.
Everything here is made in the USA from proprietary die steel with a deep blued finish, threaded standard 7/8-14 so it fits your existing press. For anyone running a 25 GT rifle and loading their own, this set brings genuine match-quality tooling to the bench.

Frequently Asked Questions
Do the neck bushings come with the Matchmaster 25 GT die set?
No, the neck bushings are sold separately. The Matchmaster sizing die is designed around an interchangeable bushing system, so you'll want to pick the bushing diameter that matches your brass and gives you the neck tension you're after. Sizing your fired case necks first and measuring is the best way to land on the right size.
Will this die set fit a standard reloading press?
Yes. Both dies use standard 7/8-14 threads, so they'll thread right into any common single-stage or turret press. That makes it easy to add these to a bench you already have set up.
What makes the Matchmaster seater die worth it over a standard seater?
The micrometer top lets you adjust seating depth in precise, repeatable increments down to a thousandth of an inch, which matters a lot when you're tuning loads for accuracy. It also uses a loading window and an internal sleeve that keeps the bullet aligned with the case for concentric seating. That combination helps produce more consistent ammo than a basic seater.
Is the 25 GT a good cartridge to reload for?
The 25 GT has become a favorite among long-range and precision competitors thanks to its mild recoil, good barrel life, and strong wind performance from high-BC 25-caliber bullets. Since it's a cartridge that rewards careful handloading, quality dies like these make a real difference in the ammo you can produce. If you're running a 25 GT rifle, dialing in your own loads is part of the fun.
