Drawn to scale from SIG SAUER’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.
Drawn from SIG SAUER, Inc.’s published specification.
In the second focal plane the subtensions are only true at one magnification — check your manual for which, and dial there before you hold.
SIG's WHISKEY4 manual p29, 'Units are in MOA at max magnification'. Published: fine crosshair 0.25 thick, posts 0.5 thick, 15 MOA from post tip to post tip across the windage (so +/-7.5) and 7.5 from the windage line down to the bottom post. Plain plex: no hash marks, no holdover points. The post tips carry a tiny 45-degree bevel (0.13 MOA) where the 0.5 post narrows to the 0.25 line; not drawn. HellFire illumination is a red centre dot (manual p8 shows only the centre lit) whose diameter SIG does not publish, so the dot is flagged illuminated with no size claimed, as the Leupold FireDot records do. Outer post ends are not dimensioned -- the sheet draws the posts as 1.35 MOA stubs -- and are run to the field edge as a display convention. Product pages list this reticle on the 2.5-10x42 and 3-12x44, illuminated and not.
Verified 8 Oct 2026 against specs/sig-sauer/OPERATORS-MANUAL-WHISKEY4-7404528-01-REV10-WEB-FILE.pdf page 29, read as vectors with pymupdf by tools/build_sig_sauer.py, which re-asserts every check on each build. scale 9.1661 pt/MOA from callout 15 (post tip to post tip); 12 published-callout edges then checked at that one scale, worst residual 0.001 MOA. The page draws the reticle as filled outlines; edges read from the vectors with pymupdf. Checked: outline is a plain cross with four posts, no marks, no numerals; centre has no drawn dot (the HellFire dot is from p8 and carries no size); post inner ends square apart from a 0.13 MOA bevel; tips symmetric on all four arms; every callout (15, 7.5, 0.25 x2, 0.5 x2) lands on a drawn edge. Outer post extent is a display convention.
