The Savage is a nice little do everything gun, my brother had one in .22/.410 when we were kids. I think you'll be pleased with it.
If you really want to get into AR-10 rifles the forum to hang out in is ar15.com. The general discussion section can get really rowdy and you'll need a thick skin, but the AR-10 sub-forum is where you can get a good answer to any question you have might have.
Like any place you have to separate those who know what they are talking about from those that talk about, but the knowlegable members are really good at keeping the knuckleheads from giving out bad information.
Lol..
Just like on any forum, how do you know that it isn't the knuckleheads that are keeping the knowledgable members from giving out good information..
I just had to say that for ironic effect. Real life is a minefield of good and bad advice.
