I'm thinking of swapping out the bolt handles on both my Savage 12F/TR, and 10FP rifles with a couple of these "tactical" models from Sharp Shooters Supply, http://www.sharpshootersupply.com/ Has anyone done this? I'm told Savage really tightens the heck out of everything at the factory, but there is a fairly large Allen type screw at the rear of the bolt. I just wondered how easy of a job this was? When working on guns I always apply Murphy's Law. If anything can go wrong, it will. Sometimes there is more to these type of jobs than meets the eye. Thanks in advance, Bill T.
