Hornady 544283 Match Grade Die Set 6.5 Precision Rifle Cartridge (PRC) Details

6.5 Precision Rifle Cartridge (PRC) (.264) Hornady Match Grade Dies give you total control over neck tension when resizing. These dies feature the ability to use interchangeable, self-centering neck size bushings that eliminate the chance of over sizing your case necks and overworking the brass. Tight tolerances at the press translate into tighter groups at the range. The easiest way to determine the proper diameter bushing, is to measure the neck diameter of several loaded or dummy cartridges with an accurate micrometer. Subtract .001”- .002” from the average neck diameter and this diameter bushing will generally size case necks to create the proper press fit for the bullet. Another method is to measure the neck thickness with a ballmicrometer. Double the wall thickness and add this number to the bullet diameter. The result is the neck diameter of a loaded cartridge, and bushing size can be determined as above.
