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

Vortex EBR-2C 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 are measured in MRAD and remain constant at all magnifications'. Published: hashes .6 at whole mils, .4 at half mils and .2 at tenths (tenths from 5 to 9 mil) on both horizontal arms and the upper vertical arm; side posts start at 9.1 and are .6 thick with a 1-mil mark at 10; bottom post starts at 11; grid dots .09 and .06. Drawn, not published (the sheet is to scale): the lower vertical axis carries .4 hashes at whole mils and .2 at half mils to 10; a dot row at every mil from 1 to 10 below centre, dots every 0.2 mil out to +/-2, 2, 3, 3, 4, 4, 5, 5, 6, 6 with the whole-mil dots the .09 ones, no dot at +/-0.2 and none at +0.4 on rows 1-9 where the row numeral sits; numerals 2 4 6 8 on the horizontal and upper arms, 1-9 on the lower; the upper axis ends at 9 and a plain line runs on from 9.1 (no top post). Posts drawn to the sheet's frame. Line .052, open centre .095 (both published on this sheet). The four axes and their hashes are illuminated (drawn red); posts, dots and numerals are not. The sheet's frame is 11.5 mil: it clips grid row 10 at +/-5.6 and the bottom post's 12-mil mark, so neither is drawn here (the Diamondback Tactical sheet, frame 12.3, shows row 10 to +/-6 and the mark at 12). The older PST Gen II EBR-2C MRAD manual (VTX_M-00015) prints '.06 (open center)' and '9' where this per-scope sheet prints .095 and 9.1; the per-scope sheet is the one drawn to scale and is followed.
How this one was checked
Verified 8 Oct 2026 against specs/vortex/VTX_PST-3158_EBR-2C_MRAD_RS_I_RI_ST.pdf page 1. Scale 15.633 pt/mil from the whole-mil hash pitch, centre (198.43, 221.1). The axes are one 1360-point red outline; decomposed from its ON-curve vertices: line 0.052 (.052), open centre 0.095 (.095), hashes 0.600 / 0.400 / 0.200 at 0.5 and 0.1 spacing, side posts 9.096 (9.1), post 0.600 (.6), post mark 1.000 (1), bottom post 10.995 (11), dots 0.090 / 0.060 (.09 / .06) - every callout lands. All 380 grid dots matched to the rule in notes; hashes centred; numerals from glyph boxes.
