From the ballistic charts I have looked at the 7mm-08 out performs the 6.5mm 260 out beyond 600 yrds. The 260 has more match factory ammo available which is a big plus. Neither have the ammo selection that the 308 or 243 Winchester do.
Just one more consideration, the 260 Rem is a 1000yrd max cartridge. The 7mm-08 has been used in competition out to 1500 yrds. It handles wind better than the 6.5mm cartridge. The father out you go the more the 7mm-08 out performs the 6.5. Food for thought.
