RCBS F L DIE SET .300 WIN SHORT MAG

Unlock Unrivaled Precision and Consistency: The RCBS 30801 Full-Length 2-Die Set for .300 WSM Reloading

Are you a dedicated shooter, hunter, or competitive marksman who understands that the key to superior performance lies in meticulous ammunition crafting? Do you spend hours at the reloading bench, striving for the perfect load that delivers unparalleled accuracy and reliability? If your pursuit is ultimate precision for your .300 Winchester Short Magnum (WSM) rifle, then the RCBS 30801 Full-Length 2-Die Set, available at DEGuns, is an indispensable cornerstone for your reloading endeavors.

This isn't just another set of dies; it's a meticulously engineered system designed to bring your fired .300 WSM brass back to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) minimum cartridge dimensions with uncompromising precision. This comprehensive two-die set addresses the fundamental requirements of bottleneck case reloading, ensuring that every reloaded round feeds smoothly, chambers perfectly, and performs consistently, shot after shot.

Why Choose Full-Length Sizing for Your .300 WSM?

The .300 WSM is a powerful, high-performance cartridge favored by long-range shooters and big game hunters for its flat trajectory and substantial energy. Maintaining optimal case dimensions is critical for cartridges like the .300 WSM, especially when used in bolt-action rifles, semi-automatic platforms, or when reloading brass that has been fired multiple times or in different firearms.

• Restoring Factory Specifications: Full-length sizing ensures that your fired brass, which expands slightly with each shot, is uniformly resized to its original, factory-fresh dimensions. This is crucial for reliable feeding and extraction in any firearm chamber.
• Universal Compatibility: Whether you shoot your .300 WSM in one rifle or switch between several, full-length sizing guarantees that your reloaded ammunition will chamber correctly every time, regardless of the rifle's specific chamber tolerances. This eliminates concerns about "sticky" bolt lift or rounds failing to fully chamber, issues often associated with neck-sized-only brass in different chambers.
• Enhanced Safety: By restoring the case to SAAMI specifications, you minimize the risk of pressure excursions due to tight chambering. This proactive approach contributes significantly to reloading safety.
• Prolonged Brass Life (with proper lubrication): While some believe full-length sizing shortens brass life, the reality is that consistent, precise sizing with proper lubrication can actually extend it by reducing unnecessary stress on the case during chambering and firing, as the brass is consistently brought back to its intended dimensions.

The RCBS 30801 set excels in these areas, providing the foundational accuracy and consistency that competitive shooters and serious hunters demand from their .300 WSM ammunition.

Understanding the Components: Precision at Every Stage

The RCBS 30801 Full-Length 2-Die Set for .300 WSM comprises two primary, highly specialized dies, each playing a vital role in the transformation of fired brass into perfectly reloaded ammunition:

1. The Full-Length Sizer Die with Expander-Decapping Unit

This is the workhorse of the set, responsible for bringing your .300 WSM brass back to its original, precise dimensions. Its design reflects RCBS's deep understanding of ammunition mechanics and decades of manufacturing excellence.

• Exterior Case Sizing: The die meticulously sizes the entire outside of the case body, ensuring that the critical body taper and shoulder dimensions are restored to SAAMI minimums. This is paramount for smooth chambering and reliable function in your rifle. RCBS holds headspace to minimum tolerances, a key factor in preventing undesirable changes to the case body length during the sizing process, which can otherwise lead to issues like premature case head separation.
• De-priming Action: As the case enters the die, the integrated decapping pin efficiently pushes out the spent primer from the primer pocket. This prepares the brass for a fresh primer, essential for reliable ignition of your new powder charge.
• Neck Expansion: Simultaneously, the expander ball, which is part of the decapping unit, passes through the case neck. This action precisely expands the neck to the correct internal diameter, ensuring that it securely accepts a new bullet without deforming the bullet or creating excessive friction. This careful sizing of the neck is crucial for consistent bullet seating tension, a direct contributor to shot-to-shot velocity consistency and, consequently, accuracy.
• Advanced Venting System: A hallmark of RCBS's thoughtful design, the sizer die features strategically placed vents. These vents serve a critical purpose: they prevent hydraulic lock caused by trapped air or excessive lubricant within the die. Without these vents, trapped air can build pressure, potentially deforming the case shoulder, while excess lube can be forced into the primer pocket, leading to misfires. This simple yet effective feature safeguards your brass and ensures clean, consistent sizing operations.

2. The Seater Die with Bullet Seater Plug

Once your brass is sized, de-primed, and primed, and a powder charge has been added, the seater die comes into play. This die is where the bullet is precisely seated into the case neck, and simultaneously, a secure crimp is applied.

• Precision Bullet Seating: The die guides the bullet straight into the case mouth, ensuring it's seated to your desired overall cartridge length (OAL) with consistent depth. The included bullet seater plug is specifically designed to fit the profile of .30 caliber rifle bullets, providing proper alignment and minimizing bullet deformation during seating. Achieving consistent OAL is vital for optimal accuracy, as it directly impacts bullet jump, pressure, and barrel harmonics.
• Integrated Roll Crimper: A significant advantage of this RCBS seater die is its built-in roll crimper. This feature allows you to secure the bullet in the case at the same time it is seated. Roll crimping is particularly effective for rifle cartridges where a secure hold on the bullet is desired, such as those used in tubular magazines (though less common for .300 WSM) or for hunting loads that may experience rough handling. It provides a firm, even crimp that helps prevent bullet setback under recoil and ensures consistent pressure upon ignition. The ability to seat and crimp in a single step streamlines your reloading process, saving time and reducing potential for errors.
