Schmidt & Bender P4FL

Drawn to scale from Schmidt & Bender’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.

Schmidt & Bender P4FL — first focal plane, MRAD subtensions

Framed to about 12 MRAD — the part of the reticle you aim with. This reticle carries marks out to 39.1 MRAD; the rest sits beyond the edge of this drawing.

Drawn from Schmidt & Bender GmbH & Co. KG’s published specification.

In the first focal plane the subtensions hold true at every magnification, so a hold is a hold wherever the zoom ring sits.

Subtensions

First focal plane, mrad, from S&B's dimensioned reticle data sheet for this scope (page 2 drawing + lettered coverage table, page 3 views of the field at lowest and highest magnification). Illuminated centre cross, then clear glass to the 1 mrad mark. Windage and upper stadia: 0.4 mrad marks every mrad, 0.2 mrad marks at the half, and from 4.2 to 4.8 a 0.2 mrad fine scale of one-sided 0.1 mrad marks above the horizontal line and right of the vertical. Heavy 0.4 mrad posts with tips 10 mrad apart. Lower stadia marked every 0.5 mrad. Ranging: a 16 mrad bar and four 3 mrad bars above it bracketing a 50 cm target at 500/400/300/200 m. Sheet letters identical to the 5-25x56 sheet: A 10, B 1, C 0.8, D 0.5, E 0.4, F 0.2, G 0.1, H 1.713 red cross, K 0.035 line, L 16 long bar at -10, M 3, N/P/R/S ranging. Post thickness 0.4 and bar thickness 0.1 are not lettered; measured from the vector drawing. Posts and the lower stadia run to the edge of the field in the lowest-magnification view (39.1 mrad).

How this one was checked

Verified 8 Oct 2026 against Schmidt-Bender-Datasheet-P4FL-FFP-5-45x56-PMII-High-Power.pdf (P4FL.zip), pages 2 and 3. Same table as the 5-25x56 sheet, letter for letter. Vector drawing, FILL geometry only (0.51 pt outline stroke dropped). Scale from A: top post tip 84.47 pt above the horizontal centreline = 5 mrad -> 16.893 pt/mrad, centre (313.02, 381.71); L then measures 16.00 at -10.00 and the post 0.400 thick. Record rasterised as the app draws it and XOR-compared with page 2 at 600 dpi (141 px/mrad): no disagreement inside the drawing, including the one-sided fine scale at 4.2-4.8 (above / right of the line). Page 3 lowest-magnification view (centre from the red cross, 3.380 pt/mrad from H): the lower stadia continue with the same pattern - 0.8 mrad marks every 5 to -35, last full mark -38, last half mark -38.5 - and the line and posts end at the edge of the field, 39.1 mrad. Page 3 draws the four short ranging bars as outlines rather than fills, so they are checked on page 2 only. No numerals on this reticle.
