Comparing figures of energy etc isn't comparing apples with apples. 7mm doing over a 100fps faster and 45gn lighter bullet doesn't mark a steel plate that I use. A 30cal cal going slower with the heavier bullet both of the same construction puts holes in it. On paper nothing between them. In real world there certainly is. Like comparing a v8-v6 4cyl with the same hp and similar toque . Put a hill in front of them and see who runs out of puff first

I’ve been halfway through a .338 edge build for the past 6 years or so. I’ve used a Winchester P14 action, but to complete that build, I need to spend a bit on a decent barrel and stock... and grow some nuts to see if the action will take it. So for now I’m just looking at 7mm cal which I really like.
