Drawn to scale from Vortex’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 Vortex Optics’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 per-scope sheet(s): VTX_SON-3901_DEAD-HOLD-BDC_MOA_RS_I_RI_ST (Sonora 3-9x50). Published, MOA at the highest magnification: windage hashes 2 MOA apart to 6, holdover hashes at 1.5 / 4.5 / 7.5 below centre, side and top posts start at 8, bottom post at 11, hash length 2, line .3, post .8. Drawn values, not published: the holdover hashes are as long as the windage hashes, every hash is as thick as the line, and each post meets the line along a straight shoulder 0.25 long. Posts drawn to 40 MOA. The manual's Class A/B/C yardages are ballistic suggestions, not geometry. Not the Dead-Hold 2A BDC. Reticle image shown for representation only.
Verified 9 Oct 2026 against specs/vortex/VTX_SON-3901_DEAD-HOLD-BDC_MOA_RS_I_RI_ST.pdf page 1 (re-downloaded from the source URL the same day, byte-identical). Scale 12.557 pt/MOA fitted to the windage hash centres at 2 / 4 / 6 (the published 2 MOA spacing), centre (198.0, 221.102); the figures read as the outline's ON-curve vertices: hash 2.000, line 0.299, post 0.801, side and top posts 8.000, bottom post 11.000, holdovers 1.50 / 4.50 / 7.50, shoulder 0.250. Every published callout is checked in tools/build_vortex_wave2.py and lands. Checklist walked: rows and extents, hash spacing, numerals, centre element and gap, post tips, which side of the line each mark sits (all centred unless the notes say otherwise), every callout.
