If a guy REALLY knows his reticle, and really knows how to range with their reticle, AND really pays attention to their magnification setting, then a Leupold Varmint Hunter's reticle is as versatile and arguably more so than a mil-dot. It requires more attention, so I'm not sure it actually makes life easier for any shooting, but it CAN have a slight advantage if a guy is willing to pay very close attention and do a lot of math. To me, irregularly spaced drop compensating retooled like these are all but worthless when compared to a regularly graduated reticle like a mil-dot, because not many people actually range with their reticle, and not a lot of people actually do "shooter math" in the field, but a lot of people do hold and correct with their reticle, where regular graduations have an advantage. So I recommend mil-dots, and recommend against drop compensators like the varmint hunter from leupold.
I can elaborate if you want the math to support my points above, but I assume not many folks aren't interested in that kind of math, which is why regularly graduated reticles have the edge in my book. I went through that explication recently with
@RussellC, the difference in use is all there.
Now cue a Zeiss fan who is convinced the Z600 is a special program which works differently than any other drop compensator and ignorantly flames me for disparaging their beloved system...
