Paper tuning: how to read and correct bow tears
Paper tuning checks the orientation of an arrow as it passes through a sheet of paper. Shoot from about 4 to 6 feet away and look for a point hole with fletching cuts close around it, often called a bullet hole. A tear shows where the nock end passed relative to the point, but its cause needs further checking.
Set up paper with a safe stopping area
Stretch a fresh sheet of thin paper across a rigid frame with an open center. Place a suitable archery backstop behind it, leaving enough room for the whole arrow to pass through the paper before the point reaches the backstop. Keep the frame and any supports outside the arrow path.
Start about 4 to 6 feet [1.2 to 1.8 meters] from the paper. Set the paper at a height that lets you shoot with your normal posture. Use a target area large enough to catch a poor launch, and follow the range's commands for shooting and collecting arrows. Nobody should stand beside the frame to watch the tear form.
Use inspected arrows of the correct length, spine and total weight for the bow. Check rest attachment, nock fit and visible fletching clearance first. Write down your starting rest and nocking-point settings. Secure any loose component to its specified setting before you test.
Read the tear from the shooting side
View the paper from the side you shot from and identify the point puncture. The torn extension and fletching cuts indicate the nock end's position relative to that puncture. A nock-right tear means the rear of the arrow passed to the right of the point. It does not mean the arrow hit right on a distant target.
| Pattern | What passed through the paper | Initial checks |
|---|---|---|
| Compact point hole with close fletching cuts | Point and nock end were closely aligned at that instant | Repeat the shot before accepting the result |
| Nock high | Nock end passed above the point | Nocking height, rest contact and compound timing |
| Nock low | Nock end passed below the point | Nocking height and rest support |
| Nock left | Nock end passed left of the point | Grip, clearance and horizontal setup |
| Nock right | Nock end passed right of the point | Grip, clearance and horizontal setup |
Use a fresh area of paper for each shot. Mark the arrow number and setting beside the hole after the range is clear. If successive tears point in different directions, inspect shot consistency and equipment before making a correction based on the largest tear.
Correct vertical tears first
The nocking point sets the arrow's height on the string relative to the rest. A repeatable high tear can call for a slightly lower nocking position; a low tear can call for a higher one. Treat those as starting tests after checking clearance, and stay within the bow maker's setup guidance.
On a compound, rest height, launcher behavior and drop-away timing can also affect the vertical tear. Keep the arrow rest within its intended working position. Moving it far from the recommended baseline to erase a tear may introduce another problem.
A high tear that survives sensible adjustments deserves a contact and timing check. Do not keep lowering the nocking position indefinitely. Have a shop assess cam timing if the bow's stops or cable system may be out of specification. A diagonal tear is easier to interpret after you have reduced the vertical component.
Handle compound left and right tears as controlled tests
For a right-handed compound archer using a mechanical release, check grip torque and vane clearance before changing horizontal rest position. Center-shot is the rest position that places the arrow in the maker's intended lateral starting alignment. Record it, then consult the tuning directions for that bow and rest.
A common initial test for a nock-left tear is a small rest movement right; for nock right, a small movement left. Some bow and rest systems respond differently. Repeat several shots after the adjustment, and reverse the trial if the tear worsens. Use repeated tears to judge whether the adjustment helped.
Stop if a clean tear seems to require a large departure from the specified center-shot range. Modern compounds may need a manufacturer-specific cam alignment adjustment. Shims, yokes and other systems are not interchangeable procedures. Use a qualified technician for work that needs a bow press or unfamiliar hardware.
Interpret recurve paper results with finger release in mind
For a right-handed recurve archer, a persistent nock-right tear can indicate a stiff arrow reaction, while nock left can indicate a weak reaction or poor clearance. The horizontal interpretation reverses for a left-handed finger-release archer. These are possible causes, not a measurement of the shaft's stiffness.
A finger release makes the shaft flex sideways, and the paper catches only one instant in that movement. A tear can therefore change with paper distance even when the bow is grouping acceptably. Learn what arrow spine means, then use bare shaft tuning to compare actual impacts over repeated ends.
Keep the recurve release natural during the test. Deliberately steering the drawing hand to manufacture a neat hole defeats the purpose. If your shots are too variable to repeat a tear, return to a comfortable target distance and work on the release before changing arrow specifications.
Verify the tune beyond the first hole
After getting repeatable compact tears, test again from a slightly different safe distance. A clean hole at one point in the arrow's flex does not prove clean flight everywhere. Then return to normal target shooting and inspect group size and clearance.
Use walk back tuning if you need to check horizontal alignment as distance increases. Keep a note of the successful paper setting so you can return to it. Your final decision should rest on repeatable shooting results, with the bow remaining inside its specified setup limits.
Questions
How far should I stand from the paper?
Start about 4 to 6 feet from the sheet. Leave enough space behind the paper for the arrow to pass fully through before reaching the backstop. After obtaining a repeatable result, check another safe distance. The paper frame must stay clear of the arrow path, and the backstop must catch every test shot.
Does a bullet hole mean my bow is perfectly tuned?
It means the point and rear of the arrow passed close together at that paper distance. It does not establish correct sight settings, ideal groups or clearance throughout the shot. Repeat the test, check another distance and confirm performance on a target before deciding that further adjustment is unnecessary.
Why does my tear change on every shot?
Variable grip pressure or release execution can change the launch. Loose hardware, damaged arrows and intermittent fletching contact can do the same. Repeat the test with inspected equipment and matched arrows, labeling each hole. If the pattern remains inconsistent, get a coach or technician to observe before making fine rest adjustments.
