No, it doesn’t. That’s not reality at all.
starting velocity and “energy” isn’t ending velocity. Ft-lbs of energy tells you absolutely nothing about how deep a bullet will penetrate, how wide the wound will be, how much expansion, or how many bones it will break.
The “sound” isn’t energy. In SAC the 6.5 CM with the most common long range loading has surpassed the “energy” of the most common 308 load at 375 yards, and it only gets worse for the 308 passed that.
If someone wants to believe some myth from someone that’s on a shooting team that fine. But it doesn’t make it true, and people shouldn’t pass it as facts.
Here is reality- given like bullets, no one could tell the difference in tissues damage or “killing” between a 308 and a 6.5CM. No one.
