The 6.5s will give you similar performance with a bullet that weighs 20 grains less than a 7mm, so the recoil will be a bit less. True the 7mm has more bullet choices but how many use 130, 145 or 154 grain 7mm bullets? Most use 140s for medium game and 160s or 175 for really big game. So the 6.5 with 120, 140 and 160 grain bullets isn't at much of a disadvantage. Me bein' obtuse prefer the 129 Hornady's in my .260.
