I think it is a mistake by Hornady to produce another 6.5 that is close to the 6.5CM. Fractionally faster and looks to be a barrel burner. Why introduce a cartridge to compete with your already successful CM? I say its more commercial hype than ballistic necessity.
220 fps same bullet, same pressures. And the Gap 4s claims tremendous barrel life.......
6.5 creedmoor: 52-53 gr case capacity
6.5 SLR: 55-56 gr
6.5 PRC: 66-67 gr
6.5 SAUM: 70-71 gr
The PRC has 25% more capacity than a creedmoor, and 5-6% less than a SAUM. In quickload, holding pressure constant at 57k psi in a 26" barrel with 140 hybrids, a 6.5 SAUM (H1000) is about 30-40 fps faster than a 6.5 PRC (H1000), and the PRC is 220 fps faster than a 6.5 creedmoor (H4350).

Been testing the new 6.5 Hornady PRC all morning, The brass is Excellent, Passed the test of 10 Loadings with a stiff charge on the 135 JLK and 147 ELD with ease. Pockets are still tight and the neck only stretched about .015". For the 135 a charge of 60.3 grains of RL26 yields 3200 fps. No pressure The 147 does 3000 with 58.2 grains H1000, light pressure . These are out of a 24" Bartlein 1-8 twist 5R. Loaded to 2.945
