That mount is not what you want on a bolt rifle. Puts the scope up too high.
The scope is undoubtedly a good quality scope. The reticle isn't what I would choose for hunting. Leupold makes a 6X42 with a heavy duplex that would probably show up a lot faster on deer.
Any major brand 150 to 180 grain hunting ammo will work for deer, and any of them is likely to shoot well enough in your rifle.
