Finally introduced in 2018 after a long period of development, the 6.5 Precision Rifle Cartridge (PRC) has the same advantages of the 300 PRC, in that it uses tight chambering- and cartridge--tolerances so it can give exceptional accuracy with factory ammunition and is easier to develop accurate loads with. Performance is not significantly greater than what can be achieved with the 6.5-06, perhaps 40 fps with heavy bullets. With a shorter case, chambering in a standard-length action allows normal seating with heavy, long, efficient bullets (such as the Berger 153.5-grain), which is beneficial. The only thing I can see wrong with the 6.5mm PRC case is the foolishly short case neck. Had the designer set the shoulder back 0.1-inch, to lengthen the neck the same amount, ballistics would be indistinguishable and barrel life would be, perhaps, twice as long. For folks working with a long-range cartridge where load development toward the best feasible accuracy and extensive shooting are likely events, barrel life matters. Cartridge designers seem incapable of learning this lesson. It is well demonstrated that case designs with short necks, e.g., 243 Winchester, 264 Win Mag, 300 Winchester Magnum, 223 WSSM, 243 WSSM, etc., always result in comparatively short barrel life; regardless of this, designers insist on introducing new cartridges with short necks. To me and to most serious target shooters, barrel life matters; it matters a lot. We will gladly give up a few-fps of muzzle velocity for a significant increase in barrel life. To each his own.
