I personally don't believe the .260 has enough going for it to take on mature bull elk in the wild. I did it once with a 25/06 but everything was darn near perfect that day and I did have a perfect broadside presentation under 200 yards. NOPE! I say the .30-06 should be the smallest caliber attempted to take bull elk. I'll drop down to the .270 Winchester for cows though with premium bullets like the 160 grn Nosler partition.
I guess you .308 Win & .300 Savage guys are SOL.
