Well, we'll all be able to find out shortly. But I just ran some numbers through various calculations, and there's no reason a somewhat larger capacity 6.5mm than the .264 Winchester shouldn't get 3400 with a 129-grain bullet, especially with a 26" barrel. And if they do, there's no reason not to meet their claim of a 415-yard point-blank range with a zero at 350 for mule deer/caribou/elk-sized game.
In fact I've run a 100-grain bullet from a 24" .257 Weatherby at about 3500 fps, sighted it in 2" high at 100, and found bullets still landed about an inch high at 300 and 5-6" low at 400. That was in typical pronghorn weather of 50-70 degrees, but the rifle did it over and over again. Why couldn't a 6.5mm 129 with a MUCH higher BC at 3400 fps do something very similar?
