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

Vortex XLR MOA
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 MOA and remain constant at all magnifications'. The centre scales are illuminated (drawn red). Published: line .1; open centre .3; centre dot .1; grid dots .17 and .26; hashes 2 every 4 MOA and .75 at the others; marks 2 MOA apart on the upper arm near the centre, 1 apart on the horizontal and .5 apart on the outer scales; side posts from 36, 2.08 thick, crossed by a 3.75-long tick (the bottom post also starts at 36 - drawn, not dimensioned). Drawn, not published (the sheet is to scale; read exactly from the vectors): see tools/build_vortex_ffp_grids.py for the full mark list - the scales run to 32 MOA left, right and up and to 32 down (dot grid), the posts' 3.75 ticks sit at 39.9, the holdover grid has a dot row every 4 MOA from 4 to 32 below centre with dots every MOA (every 4th the large one), rows widening from +/-8 (row 4) to +/-24 (row 32). Posts drawn to 43.4 MOA (the sheet's frame is 41.3). Not illuminated.
How this one was checked
Verified 8 Oct 2026 against specs/vortex/VTX_VHS-4315-LR_XLR_MOA_RS_I_RI_ST.pdf page 1. Scale 4.3555 pt/MOA fitted to the hash pitch, centre (198.0, 212.6) = 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.
