A couple of the recoil charts I've looked at shows the 260 to have slightly more recoil.
with what bullets?
I've had the 260, 7-08 and 308... Frankly, and despite recoil tables, I can't tell the difference between any of them recoil-wise, until stepping up to 180's in the 308. Even then, that's no big deal.
I find a noticeable difference between the 308 and 30-06 though...
