I am building an AR10 platform rifle for long range. I am starting with an Anderson M5E receiver / foregrip assembly. The lower is an 80% Arms that I have. Ill probably go with a Rainier ultra match barrel. Haven't decided for sure, but it will be from one of the top manufactuters.
I have read a lot about these two calibers. From what I understand it is a six of one half dozen of the other situation. The Creedmoor May feed slightly better but 260 is supposed to be acceptable and may have a slight ballistics advantage for reloaders. I'm leaning towards the 260 because I have a lot of 308 national match brass. All experience based input is much appreciated.
