"FinDot" telescopic sight reticle.The Finnish Defence Forces (FDF) 8.6 TKIV 2000 rifles have custom made Zeiss 3-12x56 Diavari VM/V T* 30 mm telescopic sights with eye safe laser filters mounted. These sights are equipped with first focal plane "FinDot" reticles (a regular mil-dot reticle with the addition of 400 m – 1200 m holdover (stadiametric) rangefinding brackets for 1 meter high or 0.5 meter wide targets at 400, 600, 800, 1000 and 1200 m). Reticle illumination is provided by a tritium ampoule embedded in the elevation turret.
The reticle elevation has 0.25 mil (0.25 mrad) adjustment intervals (total elevation range = 18.6 mils), while the windage has 0.1 mil adjustment intervals. The FDF thinks 0.25 mil elevation intervals are easier and quicker to use with Arctic mittens and that the difference between 0.1 and 0.25 mil adjustment intervals is negligible for anti-personnel sniping (0.1 mil at 1400 m = 14 cm (0.3437747 MOA), 0.25 mil at 1400 m = 35 cm (0.8594367 MOA)).
The elevation turrets have 100 m – 1400 m Bullet Drop Compensation (BDC) knobs calibrated for the Lapua Lock Base B408 cartridges the FDF issues its 8.6 TKIV 2000 marksmen. FDF snipers are trained to compensate BDC induced errors that inevitably occur when the environmental and meteorological circumstances deviate from the circumstances the BDC was calibrated for. All vital screw slots on tyhe telescopic sight are designed to be operated with .338 Lapua Magnum cartridges instead of screwdrivers.
