Article said they started by shortening, and then tweeking, a 7mm RUM, no doubt to fit a standard action.
Just checking for comparison sake...
Hornady .308 GMX 150 has a BC of .415
They list for my .300 WM the Superperformance with this bullet, 3400 ft/sec, and 5.1" drop at 300 yds.
No doubt the .26 Nosler is a tad bit flatter shooting...but not by a helluva lot out to 400 yds...beyond which most of us have no business going anyway. Thinking, sighted in accordingly, maximum point blank range for this combo would probably come almost within spitting distance of 400 yds.
Punching in some numbers on Hornady's ballistics calculator...
