Home Forums Hunting & Shooting Long Range Hunting Smaller dispersion at longer range than at close range.

The term entropy comes to mind.

Over the years, I've participated in many discussions about this phenomenon. The only credible bit of evidence that came up in support of the phenomenon was a posting by Gale McMillan on the old usenet recguns forum, which I believe was archived on yarchives. Mac described observing just such an effect while testing the 50 cal Sniper Rifles he produced for the military. I've searched high and low for that old posting recently, and can't find it now. Maybe someone with stronger Google-Fu than I will unearth that gem.

I forgot to add that there's another credible explanation for the effect manifesting in the vertical plane only called Positive Compensation.

BTW, I proposed acoustic targets when the Oeler's became available on the consumer market, but I think he's using old fashioned paper for the midrange.
