Exchange the 260 brass and dies for 6.5x55 brass and dies.
Lapua makes 6.5x55 brass. Would be a better fit n the M70.
Go light contour, you may love it so much you want to carry it in the field?
Heavy contours suck for hunting.
If you know it will never leave the bench then go heavy.
Easier to spot your shots at long range etc...
^ That. To me the advantage of the 6.5x47L over the 260 Rem is on a short action due to seating constraints. In this action the Swede would seem to me to stand out above the 260 for the same reason.
I ordered a custom tube from Rock Creek directly and they said they're 4-6 wks out. You might consider them if the contour of what you have is holding you back.
Good luck,
