[QUOTE="Jud96, post: 1235490, member: 69478"] I understand the AI outperforms the Creed without a doubt as far as speed. But that 100fps advantage is only giving you 100lbs more energy at 800 yards. According to my ballistics app, with a 140gr ELD-M with a .620 BC and 1200' altitude with standard temp and pressure for the elevation,with the Creed going 2850fps it has 1072 ft lbs and the .260 AI has 1164 ft lbs. That is less than 100 lbs of energy between the two at 800 yards. Yes its a gain, but in reality it's marginal. So in my opinion spending the extra money to have a barrel rechambered to .260 AI and then going through the hassle of fireforming and buying expensive dies is not worth it in this case. I really love the Ackleys, but I believe the OP will be more than happy with a 6.5 Creedmoor. The Creed can also function with bullets loaded way out there in any short action, the same can't be said for the .260 Ackley. I am not a supporter for any cartridge but this is how I see it.
