[QUOTE="Pdvdh, post: 761835, member: 4191"] I recently determined the actual vertical turret movement value in all three of my Sightron SIII 6-24x50mm scopes. Two have the Mildot reticle and one has the relatively recent 2-MOA reticle. Here’s what I determined: The 2MOA reticle scope has a 0.12% error (excess reticle movement). This equals a Click Value of 0.2621"/Click @ 100yds. 1st Mildot reticle scope has a 4.92% error (excess reticle movement). This equals a Click Value of 0.2747"/Click @ 100yds. 2nd Mildot reticle scope has a 6.84% error (excess reticle movement). This equals a Click Value of 0.2797"/Click @ 100yds. So two of my SIIIs have vertical turret adjustments that are substantially greater than the advertised 0.25 MOA per click. 0.25 MOA is equal to 0.2618" @ 100yds. However all three track consistently and return to zero properly and consistently. They just adjust POI a bit more than their advertised per/click values. Sightron SIIIs should be tested in order to determine the actual vertical turret values, if you're turning turrets to establish your zero for long range targets. [/QUOTE]
