I had trouble with a single red dot unless i shot at same distance , I sold my aimpoint and got a Eotech 3x 3-4 with has alot of ranging areas , granted it was designed for a AR gun and steel plates or combat as the dots and circles are good with a ar platform out to 600 yds with a 3x magnifier with a 5.56 so once you zero on your platform the dots can be used for holdover the outer ring is 68inches @100 yards so can be used for wind but it was designed to range a person as this was built for combat ,
here is what I run for red dot

Now me my self I love LVPO much better as you can really streach out the shots and precision is much better , I used to run 5 or 6 of the lvpos , Bushnell 1-6 , swfa 1x6 hd , trijicon 1-8 accu-power and my newest one I use now is called a vortex razor 1-10 , now again these were built for mid range out to say 800 yds with 308 or ar , but great for pcp guns , While the razor3 has no parallax adjustment with good glass and design it is fine in close range you get crystal clear images , however this optic went up like 140% with MSRP isince I got it , The reticle is well thought out and has a great tree type reticle good for quick follow up shots , great in low light and even magnifaction is superb compared to other ones I have tried , and Vortex is great if they ever need service ,a good company. and weighs only 21 ounces and has a 34mm tube ,
