In the first focal plane the subtensions hold true at every magnification, so a hold is a hold wherever the zoom ring sits.

Vortex VMR-4 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; the sheet: 'subtensions measured in MRAD and remain constant at all magnifications'. The centre scales are illuminated (drawn red). Published: top line .04; centre dot .04; outer horizontal line .03; whole-mil hashes .4, half-mil .2; outer scale ticks .25 at half mils and .15 at tenths; red marks .2 apart, outer marks .1 apart; outer scale to 6; side posts from 10, bottom post from 11, posts .5 thick; grid dots .06 and .09. Drawn, not published (the sheet is to scale; read exactly from the vectors): red (illuminated) centre scales to 4 mil left, right and up and to 10 down, open 0.1 at the dot. Vertical red scale: centred .4 hashes at whole mils and .2 at half mils. Horizontal red scale is NOT the same: whole-mil hashes stand 0.25 above the line and have a heavier (.05) stub below, 0.05 to 0.25, detached from the line; half-mil marks are only that stub, to 0.15; 0.2-mil ticks stand ABOVE only, to 0.1. Black outer scales from 4.1 to 6 left, right and up: centred .4 at whole mils, .25 at half and .15 at tenths, line .03; plain line from 6.1 up and from 6 to the side posts. Holdover grid: a dot row every mil from 1 to 10 below centre, dots every 0.2 mil, whole-mil dots the large ones, rows widening from +/-2 (rows 1-2) by 1 mil every two rows to +/-6 (rows 9-10). Numerals 2 / 4 / 6 on the horizontal and upper arms and 1-10 at both ends of every grid row. Posts drawn to 12.6 mil (the sheet's frame is 12.0).
How this one was checked
Verified 8 Oct 2026 against specs/vortex/VTX_VPR-52502_VMR-4_MRAD_RS_I_RI_ST.pdf page 1. Scale 14.957 pt/mil fitted to the hash pitch, centre (198.0, 221.102) = the red centre dot; every published callout then lands (all listed in tools/build_vortex_ffp_grids.py). Geometry converted exactly from the vector outlines - every rectilinear ink subpath cut into rectangles from its own vertex coordinates, one element each - so rows, widths, spacing, which side of the line each tick sits, gaps and extents are the drawing's own. Grid dots taken only on the grid; numerals placed from glyph outlines, text from the value of the mark they label.
