Hornady Matchgrade Bushing .330

The Hornady Match Grade Bushing is required for use with the Hornady Neck Sizing die. It is a self-centering interchangeable bushing for extreme precision in neck sizing. Notes: - Bushing fits in Hornady Match-Grade full length and neck sizing die - Bushing is self-centering in die body Use of Hornady Match Grade Neck and Full Length Dies and Bushings: - Hornady Match Grade dies have a separate interchangeable neck size bushing (not included with die). - The dimension of the bushing (inside diameter listed) determines the neck size when the brass is inserted into the die. - Standard dies size to SAAMI minimum specification and this is often not necessary as a particular rifle brass type and chamber may not need minimum dimensions. Less sizing results in less working of the brass. - Using some loaded or dummy cartridges that fit the rifle s chamber without excessive play measure the diameter of the case neck. Subtract .001 from that diameter and the result should be a reasonable starting point for the correct bushing dimension. Select a size that is at that dimension or just under it. - Bushings work in both the neck and full length Match Grade dies. The bushings are available in .002 increments. - The 242 244 246 and 248 bushings are for the 223 Remington and 22-250 Remington cartridges. - The 260 262 264 and 266 bushings are for the 6mm PPC and 243 Winchester cartridges. - The 332 334 336 and 338 bushings are for the 308 Winchester cartridge.
