depends on if you will be dialing in for range or windage. if you are dialing (and your dials match in moa or mill) then the mill dot/moa dot pays off because you can dial in range then use the reticle for wind or vice versa. if your not dialing in then the bdc is nice because you can just find where on the dial ring to keep the magnification to match your ballistics, but you will lack precision and extended long range ability. i have found to dials and bdc reticles (reticle in a non linear graduations) is very impracticle so dont mix the two if you do get a bdc scope. i have a preferance towards mill dot reticles with a full grid in either a fixed pwer scope or a front focal plane reticle because i can sight in at non specific ranges and work well beyond what most bdc reticles will provide. but with most types of shooting, precision (mill grid or the use of dials) is slow where as the less precise methods (bdc, kentucky holdover, bdc dial) are faster
