This expanding button is designed for reloaders who require precise control over neck tension when assembling .375 caliber rifle cartridges. It is compatible with Lyman resizing dies and can be easily installed or replaced by threading it into the die stem. Regular inspection and cleaning are recommended to maintain smooth operation and prevent the buildup of case residue.
