Attention reloaders! This is the RCBS 98876 Pilot/Neck Reamer for .20 caliber cartridges. If you're into precision rifle reloading, you know that sometimes cartridge case necks can develop imperfections, thick spots, or need slight internal adjustment for consistent bullet seating and neck tension. That's where this tool comes in. It's a precision-ground reamer designed to clean up and slightly enlarge the inside of your .20 cal brass case necks, ensuring a smooth, uniform surface. It typically attaches to a hand tool or press via its pilot shaft. Using a tool like this can help improve accuracy and consistency in your handloads by giving you perfect neck dimensions every time. It's a specialized piece of gear for serious shooters and handloaders who want to squeeze every bit of performance out of their ammunition. Made by RCBS, a trusted name in reloading equipment, you know you're getting quality. If you're working with .204 Ruger, .20 Practical, or other .20 cal wildcats, this reamer might be just what you need for that final touch of brass preparation.
