Shot Group Analysis
Group analysis is pattern reading, not fortune telling. Done carefully it points you at the right test; done carelessly it sends you chasing a fault you never had.
Look at four things in order: how large the group is, what shape it has, where it sits, and which shots fall outside it. Then form one hypothesis and test it — do not act on all four at once.
Size: how repeatable were you?
Size is the cleanest measure of consistency because it does not care where you aimed. Measure it the same way every time or the comparison is worthless.
Shape: which axis varied?
Vertical stringing often accompanies breathing, timing or hold height variation; horizontal stringing more often accompanies grip, trigger direction or wind. These are hints, not conclusions.
Position: aim, zero or both
A tight group away from centre is usually a zero conversation. A large group around centre is a consistency conversation. Treating them as the same problem is the most common analysis error.
Outliers: single events
Note where in the series an outlier occurred. A flyer on the last shot of every series says something quite different from a random one.
- Number your shots as you shoot the series.
- Record which shot was the outlier and what happened.
- Compare two sessions with the same ammunition and light.
A shot pattern rarely has one single cause. ShootMind.com combines what your target shows with your training context and your own notes before suggesting anything.
Common questions
How many shots make a meaningful group?
Five is the practical minimum; ten tells you far more. Two five-shot groups from the same session are better than one of each.
Can group shape prove a technique fault?
No. It narrows the list of likely causes. Confirmation comes from a test such as dry fire or ball-and-dummy.
