There's just no equivalent to say the .264 160gr Weldcore for .277 that will run in a standard twist rifle. Woodleigh makes a .277 180gr Weldcore, and it's a great bullet, but useless in a factory .270Win..
It's interesting in theory but I think very few people would actually ever use 160 gr Weldcores in the 6.5 Creedmoor, or the 180 gr Weldcores in a 270 of any flavour. You don't need that heavy a bullet to hunt anything you'd want to hunt with a 6.5 Creedmoor or a 270. And personally, I would want to see a test between the 180 gr .277" Weldcore and the 140 gr .277" TSX...
