This is what I had in mine,and love it .
It's reticle is half mil dot graduated for highly precise aim points .
This scope is an excellent choice for a range up to 100/120 yards.
Priced around $150 plus $15 for the side wheel,it can't be beat .
A bit heavy because the tube is 30mm (1.8 #),but worth it.
For higher magnification,maybe the one that Charlie mentioned would be the ticket .
