you'll love the scope....better optics than nightforce for less than half the cost :)

the 6-24 will be fine at 200-300....but, why NOT just go ahead and get the 8-32 or even the 10-50??? the 10-50 comes with 1/8moa clicks, as opposed to 1/4moa....and you don't HAVE to use it on the highest power....and if you decide to shoot longer ranges later on, you have the power at your fingertips already
