Actually a 4X scope is fine for most shooting we encounter around my hunting grounds, BUT if I were hunting out west where some of the shots were 150+ yards I could sure see the advantage of the better optics. When I am looking across an open field at the buck of a life time with my one shot muzzleloader, that 7X or 9X would be a great comfort to me about them.

I think the new BDC scopes are a waste of money. I had one years ago and never used the ability of it. Sold it and got a bottom lineLeupold. That Leupold was a great scope. I think if I remember the BDC scope was a Redfield, and maybe it was not a true BDC. There was a lot of fooling around you had to do. And I hunted for years with a 30-06 with a simple 4X Bushnell Banner and never knew I was out scoped. But with the new technological advantages of the optics today, they would be a real plus on the long distance stuff.
