The RCBS MatchMaster Competition Neck Bushing Die Set for 300 PRC is built for precision rifle reloaders who won't compromise on accuracy or case longevity. This two-die set pairs a neck-sizing die with a competition-grade seating die, giving you the foundation for tight, repeatable loads where it matters most—on the target. The interchangeable neck bushing system lets you dial in exact neck tension without guesswork, a technique trusted by benchrest and long-range competitors for decades.
Each die is machined from case-hardened steel with precision-drilled and hand-polished internals. The neck-sizing die uses a titanium carbo-nitride expander that reduces brass buildup during extraction and extends case life by minimizing unnecessary working of the brass. That means your 300 PRC brass lasts longer, and your loads stay more consistent shot to shot.
The seating die is where competition meets craftsmanship. Its oversized micrometer adjustment knob is marked with large, easy-to-read hash marks and letters—dial one thousandth of an inch and that's exactly what you get. The innovative loading window and built-in bullet retention system eliminate the old frustration of balancing bullets on case mouths or risking your fingers. A free-floating, self-centering stem guides the bullet into perfect alignment and seats it with outstanding concentricity, die after die.
This is serious reloading equipment for shooters building match-grade ammunition or hunting loads that demand precision. You'll need to source neck bushings separately to match your desired neck tension, but that flexibility is the whole point—it's why precision shooters have chosen this system for years.
| Caliber | 300 PRC |
| Die Type | Neck-sizing and bullet-seating set |
| Thread Size | 7/8"-14 |
| Expander Material | Titanium carbo-nitride |
| Finish | Deep blued (seating die) |
| Warranty | Limited lifetime |
No, neck bushings are sold separately. You'll need to choose the appropriate bushing size(s) to match your desired neck tension once you receive the dies.
This is a neck-sizing die set. It includes the neck-sizing die and seating die, allowing you to minimize case working and extend brass life compared to full-length sizing.
These dies feature the standard 7/8"-14 thread, so they're compatible with any reloading press that accepts standard die threads.
The loading window and bullet retention system let you drop the bullet into the case and run the press without balancing the bullet by hand. The free-floating seating stem self-centers and guides the bullet for consistently concentric seating, which is critical for long-range accuracy.
