The RCBS Matchmaster Competition Full-Length Bushing Die Set for .300 WSM brings precision reloading to your competition and hunting loads. Built for shooters who demand consistency, this full-length bushing die system lets you fine-tune neck sizing to exacting tolerances—critical for match-grade accuracy and reliable feeding. Whether you're dialing in for a precision rifle match or developing loads that shoot minute-of-angle groups, the bushing die approach gives you the control that factory dies simply can't match.
Full-length sizing with interchangeable bushings means you can adjust your neck tension without replacing dies or resizing the entire cartridge. This is the approach serious reloaders and competitors choose when factory ammunition isn't consistent enough and one-size-fits-all dies leave performance on the table. The .300 WSM is a popular magnum for long-range hunting and target shooting, and this die set is engineered specifically for that cartridge.
RCBS has been the standard in reloading equipment for decades, and their Matchmaster line represents the precision end of their lineup. If you're already familiar with bushing die systems, you know the workflow. If you're stepping up from standard dies, expect a learning curve—but the payoff in load consistency and repeatability makes it worthwhile. This is a complete die set, so you're ready to start developing loads once you have your brass, powder, primers, and bullets sorted.
This is a complete full-length bushing die set for .300 WSM. The set contains the dies needed to process .300 WSM brass. Refer to the product documentation or contact us for a detailed parts list if you need to verify specific components before purchase.
Bushing selection depends on your brass and desired neck tension. The general approach is to measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to account for brass spring-back. This gives you a starting point for bushing selection, though your final choice will depend on your specific brass, bullets, and how tightly you want to grip the bullet.
Yes. The bushing die system is designed for shooters developing precision loads where neck tension consistency matters. It's widely used for both competition shooting and precision hunting applications. If you're stepping up from standard dies or factory ammunition, understand that bushing die reloading requires attention to detail and familiarity with the system—but the consistency payoff is significant for match-grade accuracy.
The die set includes bushing(s), but you may want additional bushings in different sizes as you develop loads and fine-tune your setup. Check the product documentation or contact us to confirm what's included and what you may need to purchase separately.
