We all know people that claim a particular load shoots poorly at 100 and magically gets it s**t together at 300, 500, 1000 etc and gives a tighter MOA. I say horsefeathers and want to know if somebody can defend this with science. A bullet impacting at 1000 has a start (end of gun barrel) and an obvious ending. The arc between them is theoretically determined by observation at closer ranges and software based on bc, altitude and a few other factors. I contend that if I could shoot through tissue paper held taught every 25 yds, that the holes would be on a single arc and that the only difference between them would be the shape of the hole. They would be perfect holes at the end if we computed right and less perfect as you go toward the shooter. The bullet traveling this arc might not be perfectly stabilized and thus produce less than a perfect hole. I would concede that because of changing BC's this arc might not be completely linear. What I am having trouble conceding is a bullet off the vertical plane that pulls itself magically back on the intended path. FLAME SUIT ON! Make me a believer.
