Hi. I was wondering if it's possible to calculate bullet accuracy in terms of percentage in a series of ranges, given bullet's max effective range, a series of ranges, bullet mass and velocity with gravity (assuming no wind resistance, or any frictional resistance). I'm looking for a simple/basic formula, if there is any (this is for a game). When I say accuracy, I mean in terms of how far the bullet is from the axis of the barrell since technically the bullet can never go above it (technically accuracy should be judged without a series of shots and how close they are to a target). 100% accuracy means it would stay perfectly straight. The way I see it is, the closer a target is the more accurate the bullet is because it still has enough force to keep going straight so accuracy and range should scale proportionally and thus at a further range the bullet would be less accurate due to gravity pulling the bullet down, so the faster a bullet travels the further it can go?
