It might be enlightening for some to read the Sept. 2017 recounting of how the cartridge developed in the NRA American Rifleman. Demille and Emary, two veteran competitors and ballisticians, were at a 2005 Camp Perry shoot and began "brainstorming". They set down 7 parameters to meet for a potential new cartridge. What was easy to conclude - the .264 diameter, for its ballistic performance. In deference to the .260, they were critical of its body taper, shallow shoulder and relatively short neck. All of which could induce some axis tilt to the bullet. But they also said it wasn't an inaccurate round as it won the 2010 NRA High Power championship. But the .260 Rem. wasn't designed for precision shooting and the future round, the 6.5 Creedmoor, was meant for that very sport.
Like so many of these debates, some like to flap their keyboard over minimal issues. If you like it, fine - if you don't, then use something else.
