Leupold VX-3HD CDS-ZL 3.5-10x40
Data Provenance
Who tested: Rokslide field eval (2023-06) — read the original write-up, which is the source of record. Who structured it: Optics Intel. We extract outcomes and cite; the testing labor is theirs.
Sample size: 1 (single serial number, tested before and after warranty service) — evidence about this unit, not a verdict on every unit shipped.
Stage-by-stage record
| Tracking / RTZ | Fail | RTZ threw fliers that would miss deer vitals at ~400 yd; tracking heavily compromised per source |
|---|---|---|
| 18″ drops | Fail | first 18″ left drop shifted ≈2.5 MOA; erratic through the series |
| 36″ (single) | Fail | — |
| 3×36″ | Fail | would no longer group after; source: the erector is busted |
| Long-term | Fail | lost zero from an 8–9 mile forest-road truck ride before any drops |
Mount setup
Rings/mount: per manufacturer instructions. Ring torque: 18 in-lb. No torque caveat flagged in the source.
Notes
Same scope tested twice — the post-warranty-service retest also failed totally. Eval terminated; scope returned to owner.
