Seems that Beretta after purchasing Sako wanted faster barrel production and attempted to change that process. The Sakos affected were the finnlight models in wsm calibers. If one would notice a lot of custom gunsmiths and barrel makers have issues with making lightweight barrels out of stainless steel and also their use in extremely cold weather. Just look at the Krieger barrel site and their disclaimers concerning minimum contour barrels made out of SS. They offer 410 stainless as an alternative(higher price) for those situations. I also understand that Weatherby makes their barrels and recievers out of 410 in lieu of 416 probably because they make thin barrels out of SS. I have owned many Sakos both blued and stainless and never had a problem when purchased the gun was purchased new. I did buy a used one that some nitwit attempted to pressure point bed and had to have the gun rebedded.
