Here is my take on this old thread having owned and shot both.
After messing around with the odd rim size, various throat lengths, differing twists, pressures. I came to my Looney senses and realized I was messing with all the 6.5 oddities when I already had a perfectly good cartridge in my safe.
I can easily load my 270 to achieve the soft recoil of the Swede with matching ballistics.
The only time I can see a benefit to the Swede is when using a true intermediate length action... or for looneyism/nostalgia.
