Exact same SD = .301

6.5 cm has 26.5% less bullet weight
6.5 cm has 5.4% less velocity
6.5 cm has 35-40% less energy
Is 55.4% less recoil worth 35-40% less energy into the animal? For some it is, and for some it isn't. The energy into the animal is similar to the energy into the person's shoulder so those are the two numbers to compare. Not recoil to velocity. Do you need excessive energy to kill? Absolutely not. Do you need a Toyota or a Ford truck to pull a trailer? Take your pick. One may have a bit more power but both should get the job done.

Well said, and agree. When often that extra energy, however useful it really is, is dumped into the ground. The efficiency ratio about as high as you can currently get with the 6.5’s.
