Maybe, but I do allright and I learned that from Tom Roster at his steel shot field shooting clinic. SDGFP probably doesn' t know sh*t either as they promoted subtension as a way to range geese also. The width of ones rib is constant and it covers so much area at different ranges if you know how big your target is then you know the range. That maybe of no value to you who sees himself as a chattering monkey. Like I said before on pass shooting knowing the range and being in the lethal range of your gun and load is a good thing and will help cut crippling loss. But hey passport carry on and show us your Michigan intelligence.
