Thank you, but...it was my having found and read the linked article that prompted me to ask the question here. Vaguely, I recall several years ago a similar hit calculator was free on line at JBM ballistics but I can no longer find it.
For my practical purposes, I was looking for the difference hit probability between a 1.5 MOA rifle(the one I have) and a half MOA rifle(the one I would like to have) on a 2 MOA target at 500 yards.
Extrapolating from the graphed data in the linked article, I suspect that the gains between 1.5 MOA accuracy and .75 MOA accuracy are fairly great- particularly at ranges under 600 yards.
Again, thank you for the response. And, if someone has the software and is willing to run the simulation I would appreciate it.
