Modern action 6.5x55 data is not as hard to find as you think, Nosler lists it and several of us here are more then happy to help.The 6.5x55 is one of the nicest cartridges ever developed. It's just a very sweet balance of characteristics, non-fussy, and widely used in Sweden for moose. The recoil is mild.
On the other side of the ledger, it's an intermediate length cartridge like the 7x57. It won't fit in a short action. That, plus you have to really look to find recipes that load it to its potential in modern firearms.
You can get very similar performance with the 260, and that does fit in a short action.
I don't mind the action length at all, my Tikka comes with a long action bolt regardless of caliber. While the 260 and 6.5 Creedmore are both fantastic modern ballistic twins to the old Swede I still have a soft spot for the original.
