Smallbore Teiler table: 50 m and 100 m

September 16, 2026 · 6 min read

The Teiler is the distance from your shot hole’s center to the target center in hundredths of a millimeter, 1 Teiler = 0.01 mm. Smallbore needs two tables because two different targets are involved. At 50 m you shoot at Scheibe 3 with its 10.4 mm ten. At 100 m it is Scheibe 4 with its 50 mm ten, and the same target is used for 25 m precision and with the 50 m pistol.

Table A: smallbore 50 m (Scheibe 3)

The table works in tenths of a Teiler, the way ranges and scoring machines display the value. The upper limit still belongs to the better score, so an 80.0 Teiler is a 10.9 and an 80.1 Teiler a 10.8.

From the eight outward the full-ring limits are enough. Every ring is 800 Teiler wide, and the outer limit of ring N sits at 800 × (11 − N) Teiler.

The 50 m card is cut at the three. Rings 2 and 1 do not exist on the paper. Beyond 6,400 Teiler the shot counts zero.

The dimensions behind it

The ten is 10.4 mm in diameter, so its radius is 5.2 mm or 520 Teiler. From ring to ring it is 8 mm, or 800 Teiler. The .22 LR bullet measures 5.6 mm, so its radius is 2.8 mm or 280 Teiler. Then there is the edge rule: a shot scores a ring as soon as the edge of the shot hole touches the ring line. For a 10.0 the edge of the hole still has to reach the ten ring, and that works up to a center distance of 5.2 + 2.8 = 8.0 mm, or 800 Teiler. Every further ring ends 800 Teiler later. As a formula:

Decimal score = 11 − Teiler ÷ 800, truncated to one decimal, capped at 10.9

The result is truncated after the first decimal place, which is how the ISSF rulebook defines it (rule 6.3.3.1). A 453 Teiler computes to 10.434, and the score is 10.4. The cap at 10.9 catches the 0 Teiler, for which the fraction alone would give 11.0.

On the 50 m target the inner ten is a circle of 5 mm diameter. It counts as soon as the shot hole touches it, so up to a center distance of 250 + 280 = 530 Teiler. So every 10.4 is an inner ten. For a 10.3 the Teiler decides, up to and including 530.0 it counts as an inner ten, and at 530.1 it no longer does.

Table B: Scheibe 4 (smallbore 100 m, 25 m precision, 50 m pistol)

On Scheibe 4 the ten measures 50 mm, and from ring to ring it is also 50 mm. So the table has different steps inside the ten than in the other rings.

From the eight outward the tenths keep running in steps of 250 Teiler, and every ring is 2,500 Teiler wide.

Beyond 25,280 Teiler the shot counts zero. The complete Scheibe 4 carries rings 1 to 10. The replacement card on most ranges carries only rings 6 to 10.

Why the ten is wider

A ring’s scoring band runs from the outer limit of the next better ring to its own outer limit, and the bullet radius of 2.8 mm is added at both limits. For the nine and every ring below it the radius cancels out, leaving the 25 mm ring spacing, so 2,500 Teiler per ring and 250 per tenth. The ten has no inner limit. Its band runs from the center to 25 mm ring radius plus 2.8 mm bullet radius, so 27.8 mm or 2,780 Teiler, and divided into ten equal zones that gives 278 Teiler per tenth. On the 50 m target the same calculation comes out even, because 5.2 + 2.8 is exactly the 8 mm ring spacing.

So inside the ten, decimal score = 11 − Teiler ÷ 2,780, and from the nine outward, decimal score = 10 − (Teiler − 2,780) ÷ 2,500, both truncated to one decimal place, the ten capped at 10.9.

The inner ten here is a circle of 25 mm diameter, and it counts up to a center distance of 1,250 + 280 = 1,530 Teiler. Every 10.5 is an inner ten. For a 10.4 the Teiler decides.

Examples from a Meyton display

The values come from the scoring view of a Meyton range, photographed after a smallbore 100 m supported (Auflage) series. Meyton adds a star to every inner ten.

The 286 Teiler shows the difference to the 50 m target, where it would be a 10.6. And between 1,476 and 1,555 Teiler, both a 10.4, runs the inner-ten limit of 1,530.

Caliber

Both tables assume a 5.6 mm bullet. A thicker bullet pushes every limit outward, because its edge touches the ring line sooner. With 7.8 mm, as with the centerfire standard rifle at 100 m, the ten on Scheibe 4 ends at 2,890 Teiler, each tenth inside the ten becomes 289 Teiler wide, and the inner ten reaches to 1,640 Teiler. For 9 mm or another caliber, enter the diameter in the Teiler calculator. It uses the same formulas as the app.

How Ring Reader handles it

When you photograph your 50 m card, Ring Reader detects the target automatically, insert cards included, and scores every shot with decimal value and Teiler, whether there are two or ten holes in the paper. The Scheibe 4 center card works the same way, and if automatic detection misses, you pick the target type by hand before processing. Results from Meyton, DISAG, SIUS or another system arrive with the Teiler values the range reported, wherever the format carries them.

In “Analytics”, the “Deviation” chart type shows your average and best Teiler over time, kept separate per discipline, and under “Records” you find your “Best Deviation” for the chosen discipline. If you want to compete, every month there is the “Monthly Small-Bore Rifle Teiler” and the “Monthly 100m Rifle Supported Teiler” challenge, and the smallest Teiler of the month wins. You can view the leaderboard without Ring Reader Pro. Joining takes Pro. The tables for air rifle and air pistol have their own articles.

Frequently asked questions

How many Teiler make one tenth in smallbore?

On the 50 m target, 80, because 8 mm lie between the rings and decimal scoring divides them into ten zones of 0.8 mm. On Scheibe 4 for 100 m and 25 m precision it is 278 Teiler inside the ten and 250 Teiler in every ring from the nine outward.

Why is the ten on Scheibe 4 wider than the other rings?

Because the ten has no inner limit. Its scoring band runs from the center to the ring radius of 25 mm plus the bullet radius of 2.8 mm, so 27.8 mm. On every other ring the bullet radius is added at both limits and cancels out, leaving the 25 mm ring spacing.

Is the 50 m table the same as for air pistol?

For the tenths, yes. Both targets have 8 mm ring spacing, so 80 Teiler per tenth and 800 per ring, and the 10.0 ends at 800 Teiler. The inner ten sits differently, with the 4.5 mm pellet on air pistol it reaches to 475.0 Teiler, in smallbore to 530.0. And the air pistol target carries the rings down to 1, while the 50 m card ends at the three.
