Reticle library · SIG SAUER
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 p30, 'Units are in MOA at max magnification' (12x on the only WHISKEY4 sold with BDC1, the 3-12x44). Published: 0.25 crosshair; windage hashes every 2 MOA (callout 2), 1.50 long and 0.25 thick, drawn at 2/4/6/8 either side; hold marks below centre at 1.50, 3.75, 6.50 and 9.50, each 1.50 long and 0.25 thick; posts 2 MOA thick, starting 10 MOA left, right and above centre and 14.50 below. No marks above centre, no numerals. HellFire illumination is a centre dot whose diameter SIG does not publish (drawn with no size, flagged illuminated). The hold marks are a BDC: SIG does not state the load or ranges they are cut for, so the app treats them as plain MOA holds. Outer post ends are not dimensioned (the sheet stops them at 20 MOA and draws no field-of-view outline) and are run to the field edge as a display convention.
Verified 8 Oct 2026 against specs/sig-sauer/OPERATORS-MANUAL-WHISKEY4-7404528-01-REV10-WEB-FILE.pdf page 30, read as vectors with pymupdf by tools/build_sig_sauer.py, which re-asserts every check on each build. scale 4.1483 pt/MOA from callout 10 (centre to top post tip); 40 published-callout edges then checked at that one scale, worst residual 0.009 MOA. The reticle is drawn twice on this page: a stroked outline and a set of loose filled rectangles over the posts. The fills are oversize and were ignored; the outline's centreline reproduces every callout. Checklist: cross with four posts, bottom post starting lower than the other three; windage hashes 2/4/6/8 both sides, centred on the line (equal above and below, so not one-sided); four hold marks below centre, centred on the vertical; no marks above centre; no numerals; no floating centre (the 0.25 lines run through); post tips square; every published figure (10, 14.50, 1.50, 3.75, 6.50, 9.50, 2, 1.50 x2, 0.25 x5 and the post thickness) lands on a drawn edge. Outer post extent is a display convention.
Harson Ballistics draws this reticle at your magnification with your holdover marked on it, from your rifle, load and conditions. Works with no signal and no account.
