We had an SKS with tek sights on the line yesterday Dose any one know the come ups for this round?
As best as I can guess they are something like 3 8 8.
How about minutes per click on SKS tek sights?
I calculate 0.7 MOA/click for tech sights on an SKS.
I also calculated come-ups from Hornady Manual trajectory info for a .310" 123 grain spire-point bullet at 2300 fps muzzle velocity as 4.0, 5.3, and 6.6 MOA (round off to 4, 5, and 7 MOA)
