Forster Neck Reamer Features The Forster Neck Reamer is available in a wide range of diameters including .224 .243 .264 .284 .308 .429 and many others allowing reloaders to match their specific caliber requirements. When a case neck is too thick it can create excessive chamber pressure and negatively impact accuracy. This reamer addresses that issue by precisely removing excess brass from the neck walls. Designed to be mounted in the Forster Case Trimmer rather than used as a pilot this neck reamer cuts the entire bullet diameter evenly producing excellent symmetry and uniformity. Constructed from strong durable steel it is intended for use with unsized and untrimmed fired cases ensuring consistent results across batches.
