It's interesting in theory but I think very few people would actually ever use 160 gr Weldcores in the 6.5 Creedmoor
There's no reason not to - it's no different than the 6.5x55 that bullet was designed for. It's far and away the best bullet for elk, moose, and big plains antelope in the 6.5mm offering consistent pass through and a wide wound channel combined with a BC sufficient for long range use. If people choose not to use it, that's their own mistake.
And there's no usable equivalent in the .277 and never will be because of twist rate. Which is the whole point of this - the reasons the .277 bore diameter has become so inferior as cartridge and bullet technology has improved.
