The ballistics are undeniably awesome and so will be the blast. It’s a tad too much for me but I can’t pretend I wouldn’t be happy to have a mountain goat client lined up on his billy with one to remove more variables, if he carried his own rifle all the way there- these aren’t going to be lightweights.
No secret I’m rather traditional but also like speed, for now I’ll stick with the .270 and 7 Mag, but can’t scoff at any of the Noslers aside from their impracticality in weight for mountain backpack work. When it’s all simmered down I like the .270/.280/.284 range of capacities and rifles, as the guns can be 6lbs all up and not tear your cheek off. The .270 Sig round is interesting, appears it may pave the way to higher pressures in light rifles. But time will tell.
On a tangent if I was building a lightweight, flat shooting rifle I’d presently make it a fast twist .25-284, but ask me next week.
