Energy is a theoretical number in a calculation....
Mass and frontal area, OTOH, do not change.
The reason we argue this nonsense endlessly is that the animals we hunt are easily killed with both so it's impossible to see much difference between anything (say) 6.5 to 7mm or 30 on standard cases.
So true....at the end of the day either will work but whats the fun in that.
Aruging/learning on the internet is just entertainment we do when we can't be out actually killing animals
