How ISSF scoring actually works: rings, decimals, and the X-count

What the rings are worth

An ISSF target is a set of concentric scoring rings, and a shot is worth the number of the highest ring it touches. Land entirely inside the center ring and you score a 10; clip the edge of the 8-ring and you score an 8. Move outward and the value drops by one ring at a time. There are no multipliers and no bonus zones, just the ring the shot bites. A hole that does not touch the next ring out simply stays at the ring it sits in. A competition total is the plain sum of those shot values, nothing layered on top.

The pattern holds across every ring: value = ring number. What actually changes between disciplines is the physical size of the target and the spacing of the rings, not the arithmetic. A 10 m air rifle target and a 50 m smallbore target obey the same logic; one is simply smaller, scaled for a shorter distance.

Decimal scoring: why a 10 isn't always a 10

In qualification, a 10 is a 10, plain and simple. In finals, that same center ring gets split into tenths so tied shooters can be separated. A shot placed dead-center might read 10.9, while one that barely bites the ten scores 10.1. It is a small number with a large consequence, because fractions of a point decide medals. The decimal layer only exists in finals and leaves qualification scoring untouched.

• Decimal range inside the ten: 10.0 to 10.9.
• Nines and below are still whole numbers in most final formats.
• The exact measuring gauge is electronic in major finals; on paper targets it's a plug gauge.

For the shooter, the practical takeaway is straightforward: in a final, every tenth inside the ten counts, and the gap between first and second is settled by those fractions, not by whole rings. This is why two shooters who both "shot all tens" can finish paragraphs apart: the decimals, not the ring count, decide it.

The X-count and how ties break

The X-count isn't a bonus score. It's a tally of inner-tens, the shots landing in the deepest zone of the 10-ring, used purely to rank shooters whose totals are identical. From the ISSF tie-breaking procedure (summary)

When two competitors finish level on score, officials compare X-counts first: the shooter with more inner-tens places higher. If those are also level, the tie is broken by counting back through the highest-scoring shots, most 10s, then most 9s, and so on down the rings until someone pulls ahead. It is rare for two shooters to finish identical and then match on inner-tens as well, but it happens, and when it does the count-back settles it on the spot.

1. Compare total score. Higher wins.
2. If level, compare the X-count (inner-tens).
3. If still level, count back by ring value until the tie breaks.

How TargetLog applies the rules

TargetLog scores on-device against the same ring geometry, so what you see in the app matches what a scorer would call on paper. Each detected hole is mapped to a ring value, and finals-style decimals are computed when the discipline calls for them, so the same target can read as whole rings for qualification or in tenths for a final. A scored shot is stored roughly like this:

{
  "ring": 10,
  "decimal": 9,        // finals only → 10.9
  "inner_ten": true,   // counts toward the X-count
  "display": "10.9"
}

You can always correct a call by hand; the automatic score is a starting point, not a verdict. To rescore a shot:

1. Open the session and tap the target overlay.
2. Tap the shot you want to change.
3. Pick the ring value; decimals and the X-count update instantly.

Common misconceptions

A bigger shot group always means a lower score

Not necessarily. A tight group placed off-center can out-score a loose group centered on the ten. Group size measures consistency; score measures placement. The two are related, but they are not the same number, and chasing a small group at the expense of placement is one of the most common ways shooters leave points on the target.

The X-count and the number of 10s are the same thing

They're not. Every inner-ten is a 10, but not every 10 is an inner-ten. The X-count is the stricter subset, counting only shots inside the inner zone of the 10-ring. You can run a high 10-count and a low X-count; that gap tells you how deep into the ten your shots are landing.

Scoring rules are the same whether you call them yourself or let TargetLog's on-device detection do the work. For the full rule set per discipline, defer to the current ISSF rule book for your event. Browse more field notes →
