This is at least the third such incident involving stainless Sako/Tikka rifles and good quality factory ammunition. It does not appear to be an ammunition problem, but rather a problem with the rifle barrels.
Anyone who owns a stainless SAKO or TIKKA rifle should contact the manufacturer before firing it again.
This thread contains contact information for the manufacturer/distributor as well as pics of a blown up SAKO rifle.
