My dad came home from a banquet last night with a new toy for us.

Its is a Marlin 917vs .17 caliber, 22" heavy ss. It is a really nice looking gun. It has a grayish lamenant stock with a fox and some writing (forgot what it said) engraved in the side and a really heavy stainless barrel.
I probobly wouldn't have bought a gun like this since I don't do alot of varment hunting, but since it was free I might as well have some fun with it. Is this a decent gun? What ammo do you recomend I get for it? I have to pic up a scope yet, Im not sure which one or how much I should spend.
How much would this gun have been if I would have bought it?
