At what magnification power is the MOA reticle calibrated to? Expert Answer

This is a second focal plane, so in other words, the reticle will be consistent through the magnification.

Is this a scope that the majority of F Class .22 cal. Bench rest shooters use ? Expert Answer

However, I am unaware of what the most popular scope for that type of competition is.

Helpful Positive Review Happy6.5 shooter by The 6.5 doctor, July 8, 2019
Took the advice from the f class shooters at our club and bought the 10x50 sightron scope. Optics are very clear. Scope stays dead center on target. Adjustments are very solid. It would be nice to have Ken's caps instead of the bra.
