Lyman Flash Hole Uniformer | Sinclair Intl

This fine selection of hand tools from Lyman performs the three most important steps in achieving a clean, uniform primer pocket and flash hole in preparation for seating a new primer. Each tool features an unbreakable, comfortable, cushioned, ergonomic polyurethane handle. Flash Hole Uniformer removes burrs from the inside of the flash hole to ensure unobstructed passage of the spark to the powder for consistent ignition from one round to the next. Insert into flash hole through the case mouth, and a quick, clockwise turn of the tool does the job. Adjustable stop collar allows use with any size case, from .22 through .45 caliber.
