I have this rifle on order from Remington in a 300RUM. I would like some recommendations on what scope, mount, and rings I should put on it. I am trying to stay around the $800 range if possible. My gun shop recommended a set of Leupold rings and base for $50 and a Nikon 4-12x50 Buckmaster for $300. Is this a good setup for this rifle, and can it handle this caliber? Any help would be greatly appreciated.
