I will never let my Creedmagic know this, but my Swede will easily outrun it.
But seriously, here are quickload predictions of top velocities with popular powders you can get in america for 6.5x55 and 6.5 CM, both loaded with 143gr eldx to 62ksi in 22" barrels at SAAMI max OAL.
6.5x55 Swede:
Reloder 26 - 51.8 gr -> 2,902 fps
Norma MRP C - 50.6 gr -> 2,876 fps
Viht N560 - 50.4 gr -> 2,867 fps
MagPro - 52.6 gr -> 2,858 fps
IMR 7828 SSC - 50 gr -> 2,853 fps
Reloder 17 - 45.6 gr -> 2,816 fps
Reloder 16 - 44.6 gr -> 2,815 fps
Reloder 19 - 47.9 gr -> 2,802 fps
6.5 Creed:
Reloder 26 - 49 gr -> 2,886 fps
Norma MRP C - 47.9 gr -> 2,854 fps
IMR 7828 SSC - 47.1 gr -> 2,816 fps
Reloder 17 - 43.2 gr -> 2,801 fps
Reloder 16 - 42.2 gr -> 2,794 fps
Viht N560 - 47.0 gr -> 2,792 fps
Reloder 19 - 45.2 -> 2,773 fps
The 4.8 gr useable case capacity difference does give the old man a 16 fps advantage on the top end, and 20 - 60 fps advantage among the similar powders the two do best with. Assuming you are reloading in a modern action, don't mind loading 11ksi above SAAMI MAP and don't mind the deficit of good published load data for such loads.
I was never able to get above ~ 2,750 fps in my 22" 6.5x55 without getting a stiff bolt, but I'll admit my limitations in that I was using a sub-standard action (Rem 700) and I was mostly playing with H4350 and RL22, without much in the way of good high pressure load data available. Nothing wrong with the 6.5x55, but the juice didn't seem worth the squeeze to me, especially since there is a well marketed and widely supported easy button now that does very much the same thing.
