Reticle library · Leupold
Drawn to scale from Leupold’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 Leupold & Stevens, 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.
Official 2021 Reticles PDF page 33 table. Units not printed on the page; values follow Leupold's long-standing duplex convention (MOA / inches-at-100-yards). Columns: a=Heavy Line, b=Thin Line, c=Thin Opening (center to inner end of heavy post). VX-6HD published High-X / Low-X: 1-6x a=2.7/16.2 b=0.5/3.0 c=28.8/175.8; 2-12x a=1.4/8.4 b=0.3/1.8 c=15.3/91.8; 3-18x a=0.5/3.0 b=0.2/1.2 c=15.3/91.8; 4-24x a=0.3/1.8 b=0.1/0.6 c=11.3/67.8. Elements below use the 3-18x High-X row (a=0.5, b=0.2, c=15.3) with referenceMagnification=18. Center FireDot is present but diameter is not numerically labeled — omitted. Do not reuse these High-X numbers on other VX-6HD magnifications. Illumination: official 2021 Reticles PDF — “Fiber-optic powered center red-dot”; 2026 catalog — “NOTE: All Firedot reticles are illuminated” and “daylight-visible red illuminated FireDot in the center”. Only the center FireDot glows. Diameter is drawn but not numbered, so no invented d on the center dot.
Re-verified 11 Sep 2026 against the 2021 Leupold Reticles catalogue — page 33 for the FireDot Duplex tables and page 23 for Fine Duplex. ⚠️ CORRECTED: 'c = Thin Opening' is the FULL opening, not a radius. The catalogue's callout settles it — the c leader carries TWO arrowheads, one at the upper heavy line's inner end and one at the lower, spanning the gap between them. This record previously used c as a half-width and so drew a clear centre twice its true size. a (Heavy Line) and b (Thin Line) are thicknesses, shown by vertical double-arrows across the lines, and those were already correct. SFP: the tables publish High-X and Low-X and this record uses High-X, the top magnification, where Leupold's subtensions are true. The FireDot's dot diameter is not published on page 33, so the centre is drawn as the illuminated element with no size claimed.
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.
