This is not meant as a flame, but looking at the totality of your questions over the past few weeks, if you are also asking what MOA is, you will not get the value out of a $2000 firearm and should not be focusing on "long range" shooting. Get a solid basic rifle and master basic marksmanship, learn the fundamentals, and read a ton. A Remington SPS and a Nikon Buckmaster 4.5-14X42 scope, in the chambering of your choice, would be an affordable learning platform.
