A scope-cap card sized to your cap
A scope-cap card keeps a short range and elevation reference inside the lid. Start with our two-inch example, or enter the usable inside diameter of your own cap in inches or millimeters.
Measure the space that is actually flat
Measure the inside area available for paper, not the outside of the cap or the scope lens. Leave clearance around the rim and hinge. Changing diameter units converts the measurement; it does not resize your chosen space.
Choose the rows you need
The starting card covers 100 through 500 yards in 100-yard steps and includes Range and Elevation. Above 500, the card omits Rifle, Load, Zero and Date to make room. At 1,500 and above, it uses two tables: read down the left, then down the right. Those compact cards also omit unit labels, so keep them with the equipment and records they belong to.
The size never grows automatically. If the rows or headings will not fit legibly, the builder blocks printing and shows the minimum template diameter. Apply that size only if your measured cap can accommodate it. Your entered text is checked separately.
Enter your own records
Preset rows and manual ranges retain separate entries. The builder does not calculate elevation or convert recorded values when you change angular or distance labels. Use the records and units you intend to print.
Test before fitting
Download the blank 500-yard example on Letter or A4. Print at actual size, measure the scale, and try plain paper in the lid before cutting a laminated version. Our images illustrate placement; physical fit has not been verified. See the printing guide.
Use the print-and-photo checklist and actual-size reference outlines to record your own fit results. For help entering or pasting existing values, see transfer your recorded data.
