Re: air temp, altitude, and, air density effects
Don't know what to tell you old buddy, as a target shooter the only thing I worried about between 100 and 500 yards was wind and light, (because of using iron sights), After 600 yards humidity, temperature, altitude etc. were added to wind as factors. 100 yards is so close I honestly don't think you would get any meaningful measurements in energy differences. You certainly wont notice any meaningful difference in point of impact in up close and personal shooting at 100 yards except with lower power guns and maybe round nose bullets like a 30-30 or handgun bullets.
