[QUOTE="LkeAF, post: 2974149, member: 118231"] Naturally a larger group give you better info. My question was about why the difference in the numbers. The next two rounds (fired 5 days later with temps @ 15 colder) were 2972 and 2976. According to the online calculator that gives an SD of 3.03 for a 5 round group. Maybe not good enough for some, but I'll shoot that all day long. [/QUOTE]
