I am a beginner and have a new rifle that I need to put a scope on with a $1k budget. I'm more confused about the reticle style than scope brand. My uses are target-steel-bench and even some hunting out to 800. I can see myself using holdover more than dialing due to time constraint. Are the grid/Christmas tree style better for hold over than the mil/moa only on the cross hairs? I have never used a grid style but am concerned about making the right choice the first time.
