I find it works best to check emotional attachment at the door, and evaluate things based on merit. Can a guy kill game with a .270 Win and 150 gr Speer SP? I sure hope so, or he’s got bigger problems than BC to worry about. But do bullets exist now that give a guy an advantage over that .270/150 combo? Sure, they do.
It's not just technological advancement. The ..270 was garbage from day one. If you look at the round that supposedly inspired it, the 7x64 Brenneke, you'll see it has a 1:220mm (roughly 1:8.5") twist. This problem was basically solved already (all that needed fixing was the shoulder diameter and angle) and Winchester was too ignorant to understand what's out there. In that respect Winchester then is much like the fangirls now - too ignorant to know how wrong they are.
