I searched for this, but was surprised to not find any threads. Can anyone comment on their experiences with range estimating prairie dogs using their mil reticles (or whatever reticle variation)? I've been prairie dog shooting for about the last 10 years, using ARs, so ranging past 400 yards or so is mostly done by watching the bullet splash in the dust and using your follow-up shot. I got a new scope this year and I want to play with ranging the suckers optically. From what I can find, adults are 12-15" standing. That's quite a bit of variation to be using the mil reticle. In say mule deer hunting, the torso of adult bucks will have a smaller percentage of variation. In the past, we have just identified them as adults or pups, but not paid too much attention to their height standing or length when horizontal. I'm curious if anyone has experience that would lead me to quickly conclude if this is a good method to develop or a lost cause.
