I have a Savage Weather Warrior 116LHSS in 30-06. It was nice to shoot an accurate rifle after shooting a few borrowed/used RH action rifles. The LH action is awesome.
For me it turned out to be a great value for the $$ spent.
As for caliber recommendations, I'd do a few searches in the gun forum. Ammo availability and cost are important.
I think the 7mm will give you a bit more power & options for shots up to and past the 4-500yd range (way, way past 500 with the right bullet), if that's what you need.
Good shot placement trumps a lot of ballistic bragging.
