I am 65 and after 50 years of shooting MOA scopes; I’d like to learn to shoot one of the Christmas Tree Mill reticle. I can see the benefit. Some appear to be too busy so I thought someone could help me out. All my scopes are first focal plain Tangent theta, S and B, NF, etc. i Have no problem learning on a lesser scope if the reticle is better for someone making the transition...any help appreciated...Semper Fi..
