I would thoroughly enjoy talking to your friend about rifle telescopes, spotting scopes and exterior rifle cartridge ballistics. I’m a shooter and a software engineer who during the course of his career was able to be paid a little money studying that discipline. I wonder if it was a cold bore shot or if he had to walk it up. If it’s cold bore, then we even have to factor in barrel harmonics, pressure curve, barrel steel, Rockwell Hardness, what else? Let’s setup a Support Vector Machine, SVP, probably run the algorithmic equations under Linux. You know, just for fun. Optics and mounts are critical. Regards, kawhill
He was down at a place specializing in such weapons and training in Alabama.
