The Forster Neck Reamer is an essential accessory for the Original, Classic and Power Case Trimmers. Crafted from high-grade, wear-resistant tool steel, this Neck Reamer is designed for precision and longevity. The standard Neck Reamers are ground .0025 inches to .003 inches larger than the maximum bullet diameter to ensure optimal case neck sizing. Its staggered tooth design cuts through brass smoothly, eliminating chattering and providing a clean, consistent finish. Thick case necks can lead to excessive chamber pressures and accuracy issues, such as flyers. The Forster Neck Reamer effectively removes excess brass from the neck walls, preventing these issues and ensuring the proper neck thickness for reliable reloading. It mounts easily in place of the pilot in the cutter of a Forster Case Trimmer, making it a convenient and indispensable tool for precision reloading.
