The Forster Neck Reamer is an essential tool for reloaders using the Original, Classic or Power Case Trimmers. Manufactured from high-grade, wear-resistant tool steel, this Neck Reamer is built for durability and precision. The standard Neck Reamers are ground .0025 inches to .003 inches larger than the maximum bullet diameter to ensure optimal performance. The staggered tooth design allows for smooth cutting of brass without chattering, even on thick case necks. Thick necks can lead to high chamber pressures and cause accuracy issues, such as flyers, but the Forster Neck Reamer effectively removes excess brass from the neck walls, ensuring a proper fit. This tool easily mounts in the cutter of a Forster Case Trimmer in place of the pilot, offering an efficient and reliable solution for reducing case neck thickness to precise specifications.
