In all honesty, I couldn't find anything I could kill with the .264 that I couldn't kill just as dead with a .270.
Thus, I have concluded that belted magnums just mean more powder, more bark but the end result is the same.
I tend to agree. My lifetime animal harvest has been with 2 standard cartridges, the 280 Remington & 308 Winchester. I have taken roughly 50 big game animals from Axis, Whitetails and lesser critters. At no time did I ever feel like I needed anything else. I have owned other shooters including some fire-breathing magnums but they were only wants not needs. Shooting critters across a canyon is not for me. I have shot some across arroyos but they were all under 400 yards.
