If one must think in inches or MOA while using a MIL scope then .3 MILs is aproachimently 1 inche at 100 yards. If I want to hold off in the wind in inches that close and is close as one can hold in my experience.
The 1/3 MOA that you use is very close to MILs in adjustment. 1/3 MOA is .349" at 100 yards, .1 MIL is .366 a difference of .017. Don't see any advantage in one over the other.
