Beg to differ yall-sheperd scopes work really well once you get used to them,I have 3 mounted right now. For the average joe who don't want to learn about milliradians and such they WORK. They have the most exacting bdc on the market except for custom reticules. Try 1 yall and you'll learn to respect it-I did. I'm not saying they take the place of serious 2000.00-3000.00$ tactical scopes but they work.
