Your asking your question to the wrong group of people. What you have here are a bunch of shooters and what you need is a statisation. Several years ago I read an artical somewhere that gave the porbibality of where you bullet would hit given your group size with a varying number of shots being fired for group size. I cannot remember where I see that now. I do remember that that 5 shot groups were a hole lot better that 3 shot groups and that 10 shot groups were even better. Now you have me thinking about it, I sure wich I could find that again.
