If you shoot 1" at 100 you will shoot 2" at 200 and 3" at 300.
Metal God-again, it is not about the specific group size. As an example, 1 moa at 100 yds is 1 in. 1/2 moa at 300 yards is 1.5 in. The actual group size at 300 yards is larger, but the 300 yard groups are better than the 100 yard groups. In some specific instances the bullet may not fully stabilize at 100 yds, and is by 300 yds and groups better.
