Barnes load data shows a 260 Rem pushing a 100 TTSX to 3200+ fps and a 120 TTSX to 2900+ fps in a 24 inch barrel; and the 270 pushing a 110 TTSX to 3400+ fps in a 24 inch barrel; the 129 LRX and 130 TTSX to 3200+...
Seems to me all those bullets would do the same thing on a big deer to any reasonable range. The 270 will always offer more V, but is it needed at reasonable hunting ranges 0-440 yards? The appeal of the 270 is the max V and ammo availability. The appeal of the 260 is accomplishing the same result with less blast and recoil.
if one can't decide, the 270 makes sense for overall availability of everything...
