If you wanted to make a target face to be shot at 20yds that simulated the size of a 122cm at 100yds -

This is just as bit of fun to let beginners get a general flavour for relative size difference when shooting at 100yds - (I know this excludes the effects of wind, rain, drag, the magnification of a bad shot and all that stuff all of which is amplified at 100yds - that's not the point here).

**A)**Would you go by reducing the circle

__by 5:1, because this would represent reducing the distance from centre to the edge of a ring by 5:1 - and hence difficulty in terms of relative accuracy to a fixed point of aim?__

**diameter**

*or***B)**Would you reduce the circle

__by 5:1 - because it's the circle (or annulus) area that represents likelihood to hit it?__

**area**This is purely a mathematical type question for a bit of fun - and not seeking advice on the advisability or relevance/value of doing this - thanks.

thanks very much in advance
