Thread: Obtaining more information from your groups - overlaying groups

This for example is a group from a T3 .223 that usually averages around 2MOA for 10rd groups. The shots labeled 1,2,3 for this particular group were in fact the first 3. Other groups the first 3 are all over the place. At least it's zeroed pretty well.
