Picher is right on , bullets do not travel in a liner path . They are rotating around the straight path , that is why groups are round . There are many factors that will change the figures and ranges some what , but a good rule of thumb is 1 at 100 , 2.8 at 200 and 4.5 at 300 yards . After that the bullet does start to settle and the group sizes will start to get smaller percentage wise . There are many factors that will move the scale up or down . National bench rest champion shooters shoot 2.8x larger at 200 yards that 100 . If you do not then there is something wrong with your 100 yard load or you should be teaching the champs how to do it .
