RE: leupold VX-lll
8.5x25 is a great scope. It will be a little hard to see 6mm holes at 500 but you can usually see 30 cal holes. Although the Nightforce is great because of the 42 power, at more than double the cost for a NSX the Leupold will do just fine for the money. If you really want to spend the $$ get the March variable 60 power. A smooth $2500 will land that on top of your gun.
