Description
The RCBS MatchMaster Competition Neck Bushing Die Set is aimed squarely at the 6.5×55 Swedish Mauser handloader who wants match-grade rounds without babysitting every case. It pulls the best ideas from RCBS's old Gold Medal and Competition lines into a two-die package that sizes the neck only, keeps your brass fire-formed to your chamber, and gives you the kind of control benchrest and long-range crowds have chased for years. Everything is machined from case-hardened steel, precision drilled and reamed, then hand polished and finished in a deep blue that reads more like a fine firearm than a workshop tool.
What the 6.5×55 Neck Bushing Sizing Die Does
Instead of a fixed expander ball, this die uses interchangeable neck bushings so you can set exact neck tension by dropping in the diameter that matches your brass. The general rule is to measure the outside neck diameter of a loaded round and subtract .002 to .003 inch, which leaves a little brass springback for proper grip. Because it only works the neck and leaves the body untouched, your cases don't get overworked and brass life stretches out considerably. There's also a titanium carbo-nitride coated expander built in that cuts down on drag and brass buildup, so extraction feels smooth and the neck sees less stretch on the way through.
Seating Bullets Straight with the MatchMaster Competition Seater
The seater is where this set earns its keep for a lot of folks. It has a loading window that lets you set the bullet in and run the press without balancing it on the case mouth, so no pinched fingers and no crooked starts. The free-floating, self-centering seating stem keeps everything concentric, and the oversized micrometer knob adjusts seating depth in clean one-thousandth-inch clicks with big, easy-to-read markings.
Keep in mind the neck bushings themselves are sold separately, which is standard for this style of die and lets you tailor tension to your exact brass and load. Grab one or two sizes above and below your target diameter and you'll be set to experiment. For anyone loading precision 6.5×55 for a bolt gun, this is about as dialed-in as a factory die set gets.

Frequently Asked Questions
Do I need to buy neck bushings separately for this 6.5×55 die set?
Yes. The MatchMaster neck bushing sizing die uses interchangeable bushings that are sold separately so you can set the exact neck tension you want. A common starting point is to measure the outside neck diameter of a loaded round and subtract about .002 to .003 inch. It helps to keep a couple bushing sizes above and below your target on hand for load development.
What's the difference between this neck bushing set and a full-length bushing set?
This neck bushing set sizes only the case neck and leaves the body untouched, which keeps your brass fire-formed to your chamber and reduces case stretching. That approach is popular with precision bolt-action shooters who fire and reload the same brass repeatedly. A full-length bushing set resizes the entire case back toward factory dimensions, which is the safer bet if you rotate brass between rifles or want maximum feeding reliability.
What makes the MatchMaster Competition seating die worth it?
The seater has a loading window that lets you drop the bullet in and run the press without balancing it on the case mouth, so setups are quick and your fingers stay out of the way. Inside, a free-floating, self-centering stem keeps bullets seated concentric for better runout numbers. The oversized micrometer knob adjusts depth in clean one-thousandth-inch increments with large, easy-to-read markings.
Can I use this die set without sizing the inside of the case neck?
You can. The decapping rod comes pre-installed with the titanium carbo-nitride expander ball, but RCBS includes a separate decapping pin holder in the box for anyone who prefers to skip the inside neck sizing. That flexibility is handy if you turn your necks or rely on the bushing alone to set tension.
