RCBS Small Base 2 Die Set .30-06 Springfield

• Small base sizing: The sizing die reduces the case body and shoulder slightly below standard full-length dimensions, which helps fired brass chamber more reliably in tight semi-automatic, pump, and lever-action rifles.
• Two-die loading workflow: A dedicated small base sizer and a regular seater die cover the core steps of rifle reloading, keeping setup straightforward while still handling sizing, decapping, seating, and crimping.
• Built-in roll crimp: The seater die can crimp as the bullet is seated, helping maintain bullet retention for cartridges that may see repeated feeding or recoil in the magazine.
• Steel die construction: Steel sizing surfaces are suited to repeated use on bottleneck rifle brass, giving the die set the durability expected for regular .30-06 Springfield loading.
• Made for .30-06 Springfield: Caliber-specific geometry supports consistent case preparation and bullet seating for one of the most widely used hunting and field rifle cartridges.

About the Small Base Series

RCBS Small Base die sets are built for reloaders who need ammunition to feed dependably in rifles with less tolerance for marginally sized brass. Within the RCBS rifle-die lineup, this series sits alongside standard full-length and neck-sizing sets, but it is aimed more directly at semi-automatic, pump, and lever-action rifles where reliable chambering is often a higher priority than minimizing case working. The defining feature is the small base sizing die, which sizes bottleneck cases slightly more than a conventional full-length die by reducing the body and shoulder a few thousandths.

That design makes the series especially relevant for hunting ammunition, field rifles, and repeaters that must cycle smoothly under practical conditions. RCBS pairs the sizer with a regular seater die, creating a simple two-die format that covers the essential loading steps without adding unnecessary complexity. In use, the series is characterized by straightforward adjustment, conventional 7/8 x 14 die-format compatibility, and a practical emphasis on dependable function. For reloaders working with bottleneck rifle cartridges, Small Base sets offer a sensible option when chambering reliability matters more than preserving every possible bit of brass life.

About the RCBS Small Base 2 Die Set .30-06 Springfield

The RCBS Small Base 2 Die Set .30-06 Springfield is intended for reloaders producing ammunition for rifles that benefit from tighter, more uniform case sizing. In this chambering, that matters because .30-06 Springfield is used across a wide range of hunting and utility rifles, including actions that can be less forgiving of brass that is only minimally resized. The small base sizer brings the case body and shoulder down slightly below standard full-length dimensions, helping loaded rounds chamber with less resistance after repeated firings. In practical terms, that can reduce stoppages and make feeding more predictable when reliability takes priority.

The set combines full-length sizing, decapping, and bullet seating in a simple two-die arrangement, so it suits reloaders who want a conventional workflow rather than a match-style multi-die setup. The included seater die uses a built-in roll crimp, which is useful when loading ammunition that may be cycled through the magazine repeatedly or carried in the field. Because the crimp function is integrated into the seating die, the set remains compact and easy to set up on a standard press.

Steel die construction supports long service life, while the standard adjustment format keeps the dies familiar for established handloaders. For .30-06 users loading for dependable field use rather than benchrest-only applications, this set is defined by reliable chambering, straightforward operation, and caliber-specific fit.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from “Rock Chuck Bullet Swage,” the original bullet-swaging die that started the business. From that beginning, RCBS developed into a specialist in ammunition handloading and reloading equipment for rifle and pistol cartridges.

Its product range covers the core tools of metallic cartridge reloading, including presses, dies, shell holders, powder measures, and priming tools. RCBS is particularly well known for building complete reloading systems, from single-stage presses to turret and progressive designs, giving the brand a long-standing presence among both new and experienced handloaders. The company remains based in Oroville, California, United States, and its focus on practical, workshop-oriented reloading tools makes it especially relevant in categories such as rifle dies and case preparation equipment.
