I've recently discovered the Horus Vision reticles and like them for preision shooting both for subsonics and long range high power cartridges. I use a laser to determine distance and an ultrasonic anemometer to check the shooters position crosswind. (and modify that with available visual clues from mirage and plant movement downrange). Then a lookup table (or PC) gives mils offset to tenths each axis. Then just move the target to that position on the reticle and fire. There are no knobs to twiddle or clicks to count other than initially zeroing the scope. The Horus Raptor with the H25 reticle is a good choice for a subsonic in my opinion. If you need more vertical than 15 mils (over 50 moa) the H37 reticle is available in the Horus Falcon model. .
A Mil Dot reticle can be used in the same manner, but only has 10 mils (36 moa) of range on the reticle and you can only roughly guess the correct position when both the elevation and windage have a significant offset. This may look complex, but functionally is just a mil-dot reticle with the blanks filled in. Each major division is one mil with ticks at 0.2 mils. Unlike BDC reticles or knobs it's not bullet/velocity/atmosphere specific. It will work with any cartridge and bullet. It's the best scope I've found if you don't like the "spray and pray" method of aiming and find target knobs to be too slow and error prone. The Horus scopes are made in Japan and (my opinion) are of similar quality to Nikon or Weaver.
