M193 ammo has a mean radius of about 1MOA, but the ES for a 10 shot group runs about 3 inches. Frankly, I think the 3 moa number is more relevant. Take 10 shots and they will be in there somewhere.
Red cone for the red dot 'coverage' and black bars for typical distribution of shots.
I think this is great.
If I'm understanding your post, the red cone would be 1/2 the size for his 1 MOA Vortex UH1.
It looks like you used 3 MOA as the typical dispersion for the XM193, for the black bars. Would be accurate to extend the bars to 5 MOA for the 2 MOA dot, and 4 moa for the 1 MOA dot?
It would also be useful to shade the cones along the trajectory arc.
Sitting back and looking at the results - with the extensions as you posted and with the ones I surmised might be accurate for dot size - I still get the same results in terms of why I select 50 or 100 over 25 or 36 as a zero range. Although, I may be inclined to switch from jugular notch POA to sterum POA.
