I'm a 6.5 Creedmoor kind of guy, but this thread certainly has my curiosity piqued. Stainless T3x Lites are so cheap in .300 WM and WSM. It would be a hunting rifle only to supplement my T3x Lite 6.5 CM. I really don't need one, but dang...
IMO the perfect stable of precision calibers looks like this;
A short action 6mm or 6.5mm variant
A 300 magnum that suits your needs be it 300PRC, 300WM, 300 Norma, or a RUM
And either a 375 Cheytac or a 37XC..............< One day I'll get around to this.
