6.5 PRC vs 7mm PRC
Typical factory loads side by side: speed, energy, BC, twist, range and what each one is built for.
The short answer
With typical loads, the 7mm PRC is about 40 ft/s faster at the muzzle (2,960 vs 3,000 ft/s).
The 7mm PRC carries about 26% more energy at the muzzle (3,497 vs 2,782 ft-lbs), which usually also means more recoil.
The 7mm PRC's typical bullet has the higher BC (0.689), so it holds speed better and drifts less in the wind at long range.
