I have found over many years of shooting savages the bolts tend to become smoother with use, i have a model 11 that has been a switch barrel for many years and is butter smooth because of the round count through it. I have a new 10 fcp-k that is stiff at the moment but it only has 10rds through it so far.

I have also found that easy to open bolts can open while being carried, since it has happened to me in the past.
