Redding Bullet Seating Micrometer STD #18 Seat Plug

The Redding Bullet Seating Micrometer STD #18 Seat Plug is a precision replacement component for reloaders who demand accuracy in ammunition assembly. This standard-profile seat plug integrates with Redding's proven seating die system and provides direct interchangeability across compatible dies, enabling shooters to switch between different cartridge applications without purchasing duplicate equipment.

Designed for bottleneck cartridges with traditional bullet shapes, the micrometer-style seat plug allows fine adjustment of bullet seating depth—a critical variable that directly affects pressure curves, velocity consistency, and accuracy. The compact 4.55-inch length and 0.75-inch width make it easy to store and swap between dies when transitioning between different calibers or reloading stations. Redding's modular approach means serious reloaders can build a complete seating die collection without redundant components, reducing both cost and storage requirements.

This product is purpose-built for handloaders who reload multiple bottleneck rifle cartridges and require consistent, repeatable seating depth across different ammunition batches. Whether loading for precision rifle, competition shooting, or field hunting applications, the ability to precisely control bullet seating depth ensures uniform cartridge specifications and predictable ballistic performance. The seat plug's compatibility with standard Redding seating dies makes it an essential accessory for anyone managing a multi-caliber reloading operation.

Redding Reloading Equipment is recognized in the handloading industry for manufacturing precision tooling that meets the exacting standards of competitive shooters and serious reloaders. Replacement seat plugs like this one maintain component consistency across your reloading bench, ensuring that your dies perform predictably whether you're loading your first batch or your thousandth.
