Nope. Nice try but not even vaguely close mate.
Both examples I gave above are using the same muzzle velocity (3,000 ft./sec). Which is a realistic muzzle velocity for both cartridges using those common and popular bullets, not the hottest load and by no means the slowest. It’s the most sensible way of demonstrating the difference between the two cartridges at the range our mate here told us he wants to be able to shoot large deer.
And why when shooting large red deer in particular, I have come to the view that one is more suitable than the other.
I get the .243 fanboy reticence to see the issue for what it is. Remember I have been a .243 shooter since I was in my early teens, 40 years ago. I can out-fanboy the best when it comes to loving the .243 Winchester. In that time there’s only been a handful of years that I have not been in possession of one. I know the cartridge inside out and back to front, just like you.
I also know what 30% more thump looks like at the business end….
