To some degree we ourselves are spoiling our fun....
By the way we measure our groups....
I explain.
The way we usually measure groups is the
EXTREME SPREAD method.
In a 10-shot group we measure
only the 2 shots that are farthest apart from each other, say, 1.5 inches apart.
And
ignore the quality of the other 8 shots...! Which could have been all in one ragged hole of 0.5 inches. But: Our performance measurement method EXTREME SPREAD does not care, nor does it tell us the whole story. It leaves us with the fragmented knowledge of 2 shots only.
Thankfully, there are more reliable measurement methods that measure MEAN SPREAD (two of the common ones are
mean radius and
CEP).
These MEAN SPREAD methods take all 10 shots into account to indicate our shooting performance. And the more shots you take the closer your result represents the true performance of your gun or you the shooter (statistically reliable). Very much unlike the EXTREME SPREAD method where results get worse and worse the more shots you send at the target.
➔ I use
RangeBuddy (Android; on IOS it's called
Sub MOA) and
TargetScan (both systems) to measure mean radius, and there are others, some free, some for a small fee.
