TC Encore with a Nikon BDC scope. I am very comfortable out to 200 yards with it.
I am sure the $300 difference is materials, machining specs and tolerances. I doubt that TC believes it can an extra $300 just on name recognition, and CVA is 1/2 the price because of mftg shortcuts, materials, or less stringent machining specs.
Spend as much as you can on the scope. Better glass, better low light transmission at critical times.
