re: .308 or 6.5 creedmoor for deer hunting?

My post wasn't very clear, UpToPar. I've killed three deer w/ the 260 Remington (ballistically equivalent to the 6.5 Creedmore) in a bolt action handgun w/a 15" barrel. I've also killed 25 deer w/ a 6.5 JD (equivalent too the 6.5 Grendel) in a 14" barrel T/C Contender. Since my muzzle velocity is less in the shorter barrels, I use lighter, 120 gr bullets. Almost all the 6.5 JDJ kills were w/ the 120 gr Nosler Ballistic Tip. The two killed w/ the 260 Rem last year were w/ the 120 gr Speer spire point (now discontinued). I'd think the 130 gr Nosler AccuBond, 125 gr Nosler Partition and 140 Nosler Ballistic tip to also perform well in the 6.5 CM. The Ballistic Studies website has a good breakdown on real world experience w/ various 6.5 bullets in the 6.5x55, also equivalent to the 6.5 CM. A lot of the bullets loaded in the 6.5 CM are fairly new so there's not much mention of them in the link.
