RCBS 0.218" Tungsten Neck Sizing Bushing is coated with Tungsten Disulfide for frictionless operation without traditional case lube.
Designed for use with RCBS Gold Medal Match neck sizing dies, ensuring precise bullet tension for consistent shooting ammo.
To select the correct bushing size, subtract .002" to .003" from the loaded cartridge's outside neck diameter or calculate based on case neck wall thickness and bullet diameter.
