I really do appricate the answer's and help I am getting from everybody. After Looking at the picture's of the scope's that Steve sent in,it look''s as if the taller one would be more comfortable to shoot.
As to the picture's 1KPerday sent in, I didn't see any difference between the 2 grade's. It is to late as I sent in my order for the special grade this morning.
Now I get to spend the rest of my money on accessorie's. Oh well that's life.
I really enjoyed the u tube video but couldn't tell what you were shooting at.
