The 7-08 is inhertily less accurate than the .260 its the hardest caliber knowen to man to keep shooting straight and will loose accurcy over night.
I've got 4 sub moa .284 rifles, two of them 7-08's. I've never had a hard time.
you know that 260 will penetrate where a 7mm will just bounce right off....admit it!
Chuck Norris invented the 260.
I also have a 6.5x55, I could live with any of the 6.5, .277 or. .284 caliber cartridges based on the .308, Swede, 30-06, .284Win or 7x57 cases.
