Should be a shooter. What type of barrel?

In all likelihood, the rifle will shoot certain weights better than others. It will probably shoot all of them 'well enough,' but certain ones are going to outperform others. I would recommend asking him for the load data on that rifle, at least that will give you a baseline to start with.

Time & true basically just makes the action smoother (bolt lift/manipulation, etc.). Not exactly sure what it entails, but I'm sure Fred will tell you if you call. It's a very common service for Savage owners, and he definitely knows what he's doing.

Based on the brief description, it should serve you very well based on what you're looking to use it for.
