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.
Ballistics is what keeps the energy until it gets to the target, poor ballistics = faster loss of energy, that’s the appeal of long skinny bullets and the advantage high bc’s give. Probably common sense but I just figured I’d add it to the conversation. It’s what I like about the heavy for caliber bullets and the reason I like the 6.5’s.
