Vortex EBR-7C MRAD
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.

Subtensions
FFP; subtensions valid at all magnifications (sheet: 'MRAD values are correct on all magnifications'). Geometry rebuilt from the maker's subtension chart. Printed callouts: 0.5 / 0.3 / 0.2 are TOTAL hash lengths (integer / half / 0.1-mrad marks on the upper stadia), 10 = position of the 1 mrad tick across each side bar, 11 = top of the bottom bar, 0.5 = bar thickness, centre dot 0.04, tree dots 0.06 (0.2 steps) and 0.09 (integers). Measured, not called out: side-bar inner ends at 9.0 (the line stops at the 8 hash; gap to the bar); floating centre dot with the fine lines starting 0.11 from centre; horizontal has 0.2 mrad up-only marks (0.25 long) and heavier 0.5 mrad down-only marks (0.3) out to 4, integer hashes 1-4 are 1.0 tall, then a 0.1 mrad fine scale from 4 to 8; vertical above has 0.5 marks to 4 then 0.1 fine scale to 10; below centre the 0.5/integer hashes are 0.2/0.4 total; thin field line resumes 0.5 above the 10 hash. Christmas-tree rows 1-10 span +-2,2,3,3,4,4,5,5,6,6 with dots at 0.2 steps starting at 0.4, numbered at both ends. Numerals 1 2 3 4 6 8 above the horizontal both sides, 2 4 6 8 10 right of the vertical. Line weight is not published; 0.03 is the drawn weight scaled, not a maker figure.
How this one was checked
Compared against scratchpad/specs/vortex/vortex-ebr-7c-mrad.pdf (VTX M-00271-1), PDF page 2 = printed pp 2-3 subtension chart, rendered at 600 dpi. Scale calibrated on the vertical 10 mrad hash (634 px) and cross-checked on the horizontal 8 (same 63.5 px/mrad); every callout (0.5/0.3/0.2 lengths, 10 tick, 11 bar, 0.5 bar thickness, 0.04/0.06/0.09 dots) measured within 0.02 mrad. Hash spacing, fine 0.1 scale, tree row widths and dot pitch, printed numerals and their positions, floating centre, bar tips and bar ticks all checked; numerals hidden by callouts on the right diagram confirmed on the uncluttered left diagram.
