You may very well be right. I didn't look too closely at the charts. But if you take a mid weight 6.5 bullet (say 130gr) and a mid weight .22 bullet (50gr) I would assume the 6.5 swede would drop more. Now if you loaded the light 85-90 gr bullets in the 6.5 you might be flat as the .22-250 again, but you end up with a bullet that doesn't buck the wind very good anymore either.
The fact is you can turn the 6.5 Creed into almost a .22-250, but I think you will end up giving up some of its supposed merits to get there, namely the Ballistic coefficient you get with heavy, long slippery bullets (which the light for cal bullets likely won't be) and the ability to shoot heavy bullets, which the 6.5 caliber cases are known for. But I may be barking up the completely wrong tree.
This is all just my opinion. YMMV
