If you own a 308 there is no "need" for a 26 cal.
SO WHAT?
We buy what we want because we want it. "Need" has little to do with it. Freemen buy what they want. Slaves are given what they need.
The 260 is the "American 6.5 Swede" and will match the Swede's performance on game with the same bullets going the same speed.
What's not to like?
If white tails are the only big game on the list, I can assure you the 26s will do all you'd every need them to do. And they do kick less, and can fly flatter, but the flatness of the trajectory is more a marketing ploy for a deer hunter, and had little to do with the real world. Even the 308 with a 180 grain flies flat enough for white tails, in 98% of the cases.
Instead of wrestling over the "need" just go get one and enjoy it.
If need for flat trajectory was really important to you the advice given above in this thread to just load your 308 at 3000-3100 FPS with Barnes 130 grain bullets is as good as any advice here. Works great and is less expensive then a new rifle and scope. But maybe not as fun.
