Re: new to long range shooting.
The newer Savage rifles generally shoot pretty good. BSA scopes are a little uncommon around here, but that doesn't mean it won't work. I wouldn't rely on it for continued dialing in elevation or windage, but if you get a good zero than it may hold it fairly well so I would utilize the power setting and the mildot for hold over rather than adjusting the knobs for distance shooting.
As for the ammo, every rifle has it's own "taste", so you will just have to try some out. Some will shoot better than others in any particular rifle. 308 has about the best selection for match grade ammo available from the factory so that is good.
Only one way to find out so go ahead and shoot some ;)
