Referring to only the current online Nosler loading manual, it shows a 6.5 129gr ABLR capable of 2900+ out of a CM. It also shows a 270 Win w/140gr AB capable of a bit more (but not much) velocity. Both bullets have a high BC and a high SD. The ABLR opens to a lower fps. Both hold together as they are bonded. The 270 is seldom questioned as an elk killer yet the 6.5 is. One is as good as the other on the performance end and I'll take less recoil and short case. They both kill well with good shooting and I've used both. Mac
Come on, .264 vs. .277! All the difference in the world! I read it here somewhere...
