Please don't laugh. I am an old man that has used scopes for years, bad eyes since a kid. The scopes I have used have always been just a plain cross hair , Duplex hair or the old post design, What is it with these new scopes that have the military recticle? What are all those lines below the center cross hair ? Sometimes the scope will have these as just straight lines and others have them in somewhat of a bottom of a hour glass design. This is something all new to me.
