I was going through my 308 hog hunter the other day and noticed that the bolt is hard to close with an empty chamber. I mounted it in an accustock with the proper recoil lug and material removed to accept the top bolt release receiver. The bolt runs smooth in the action until you just start to close it, then there is resistance and it closes with some added effort. It doesnt take a whole lot of extra effort but enough that I noticed it wasnt as smooth as my other Savages. Anyone have an idea as to why this would happen?
