Thread: Obtaining more information from your groups - overlaying groups

Interesting thread, and hopefully I can contribute next time I get the range.

I've wondered at times if 3 x 10 shot groups would yield the same results as 10 x 3 shot groups (especially across different sessions). There seems to be a certain set of skills involved to maintain consistency while shooting larger groups (excuse the pun), to avoid shooter fatigue, manage barrel heat/mirage, and sometimes to overcome discouragement when you start to see a group open up as put more rounds into it. At the other end, there are what I guess could be called "cold shooter" effects - maybe these get evened across a larger group?

I've posted this image before, however seemed relevant. Interestingly the first three shots were close to the central X (approximately 1/2 moa or less) and then opened up from there.
