I'd have to disagree, if you're reloading you have a bit more capacity but both fit in an AICS mag. There are lots of 260's in the precision competitions and no one is single loading them. I was able to get 2810 FPS in my savage LRP 6.5CM with 41.7 of H4350 with 140Amax, 139 Scenar was pretty much the same, but the scenar is more consistent at longer distance. IMO if you're reloading it's a wash between the two, though you have more choices for brass. If you aren't reloading the 6.5CM would be the preferred choice for me as you can buy match quality ammo for a lot less than than the .260 or even the .308.
