I found the following about Savage bolts on the web (so take it with a grain of salt):
"In a few early production rifles there were several reports of the "bolt head retaining pin" that holds the bolt head to the bolt body cracking under heavy usage . This would cause a major stoppage. This was apparently a fluke as there have been no further reports of this problem and I believe that bolt pin breakage is no longer an issue and that there is no need to be concerned.
However, when notified of these incidents Savage Arms, to their great credit (and something other firearms manufacturers could learn from), immediately investigated the bolt head pin problem. While they were unable to duplicate the failure after some exhaustive testing they did come up with a way to beef up this part of the their scout rifle by using their "magnum" bolt head assembly.
The Savage Arms' bolt assembly incorporates a floating bolt head to assure full bearing on both locking lugs. To achieve this, a bolt head retaining pin is used as a "pivot" point. The firing pin passes through a hole in the retaining pin and is ultimately guided/supported by the bolt head. To increase the cross-sectional mass of the bolt head retaining pin in their magnum assemblies, the diameter of the firing pin hole through the pin was reduced."
