they will mount and bore sight it for you for free. That vx-1 will be a hell of an up grade for you and you will like it.
Gun ranges often have a bore sighting service. I don't know if Cabela's does, but I would say it's a safe assumption. Give them a call before you go.Here is how I bore sight a bolt action. I get a good size cardboard box and cut two notches so the rifle will cradle the long dimension of the box. Remove the bolt and sight down the bore at a target maybe 25 yards away. Without bumping or moving the box, turn the elevation and windage screws until the crosshairs line up on the target sighted through the bore. A do it yourself method, should put you on paper at 100 yards.
I'd go with the VX-II in a 3-9x40 if you can afford to spend just a little more. It's a great scope for the money. I think they're just a hair over $300. Anything less and you may be wanting to upgrade in the near future and you'll be money ahead to just spend a bit more now.
