NOT to dispute nor argue with anyone.
I have a Win 70 XTR FTWT in 6.5 Swede and W W and Rem factory brass works without any problems. I also have a couple of boxes of PRVI but I haven't messed with them yet.
OTOH - I have RCBS shell holders and MY 6.5 brass would not fit the No.3, I had to get a No. 2, which works perfectly.
TECHNICALLY speaking or Nit Picking the Swede's Rim OD is .479
While the 06's Rim OD is .473
so the answer to your ? is --NO, they're not exact.
