How shot scoring works¶

ShotTrainer calculates a score for each shot using the currently selected target face. The scoring rules are designed to match the way paper targets are scored in competition.

Depending on the target definition, a shot that touches a scoring line may count as either the higher or lower score. This behaviour is controlled by the target face and supports both inward and outward scoring systems.

How scores are calculated¶

Each target face defines scoring rings. The session supplies the shot diameter.

To score a shot, ShotTrainer measures the distance from the centre of the target to the centre of the shot, then determines which scoring ring the shot reaches.

The scorer works from the highest-value ring outward. The first ring touched by the shot determines the score.

Because the projectile has a physical size, scoring is based on the outer edge of the shot rather than its centre. If the edge of the shot touches a higher-value scoring ring, the shot receives that score.

This describes inward scoring. Outward target definitions use a strict boundary comparison, so a shot exactly on the boundary can receive a different label. The supplied definitions are training aids, not certified competition scoring.

Shot diameter and calibre¶

The shot diameter setting determines how large the projectile is for scoring purposes.

You can configure this in:

Session settings > Shot diameter

A larger diameter means the shot can reach a scoring line from slightly further away, which can affect close scoring decisions.

Common values include:

4.5 mm for air rifle and air pistol pellets
5.6 mm for .22 LR ammunition

You can also enter a custom diameter if required.

X-ring scoring¶

Many target faces include an X-ring at the centre of the target.

Shots that land in the X-ring are displayed as X rather than 10.

For scoring totals, an X counts as 10 points. For example, ten Xs still produce a total score of 100.

The X count is commonly used as a tiebreaker in competitions and does not award additional points.

Target faces¶

ShotTrainer includes target faces for a range of common disciplines, including air rifle and smallbore shooting.

You can also create your own target definitions.

Saved scores¶

Saved scores remain unchanged when settings change. Choose the appropriate target face before recording. The interface has no re-scoring action.

When no target face is available¶

If no target face is selected, or the selected face cannot be loaded, ShotTrainer cannot calculate scores.

Shots will still appear on the target view, but:

The score column displays -
No total score is shown
Score-based statistics are unavailable

Once a valid target face is selected, scores can be calculated again.
