Re: Just out of curiosity...........
Well, I am not sure what kind of game or what bullet, but if you use a 178 AMAX at 3000 FPS at standard air it will have about 1500 FPS at 975 yards. That is also about 900 FPE.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
