[quote=jwallthat the 260 is BEHIND the 270 until 650 yds.
(upper case for emphasis only)
Seriously, my only point was to point out that the 260 DOES NOT outperform the 270 everwhere in every way AS SOME PROPOSE. Actually I would have to LOAD DOWN my 270s to equal a 260 for MODERATE ranges. (Using comparable s d & b c)

Behind in velocity, not in all aspects.
The .260 has an advantage in wind drift at any distance that wind would make a difference. You would need a .270 Weatherby with a couple hundred fps more muzzle velocity than the .270 Win to match the .260 on wind drift.
At moderate ranges, the real choice between a .270 and .260 ballistically is whether you want 15 or 20 yards more in max point blank range (e.g., 295 vs. 277 yards), or whether you want more margin of error with respect to variable winds. Beyond MPBR, you're going to have to compensate for trajectory anyway. The difference in recoil doesn't depend on what distance you shoot.
