Holdovers
Once the distance has been calculated using the TMCQ MOA reticle
or a laser rangefinder, the TMCQ MOA can be used for rapid holdover
correction for bullet drop of the cartridge being used. To get the most
benefit out of the TMCQ MOA equipped riflescope, Vortex Optics
highly recommends shooters learn their bullet drop numbers in MOAs
rather than inches. Since the TMCQ MOA reticle is scaled in 2 MOA
increments, it is an easy job to quickly select the correct drop reference
line once the shooter knows their bullet drops in MOAs. If the shooter
prefers to dial their come ups for bullet drop using the elevation knob,
knowing bullet drops in MOAs rather than inches will allow for much
faster adjustments as the MOAs can be quickly read on the elevation
knob.
8 MOA holdover for 5.56 mm at 400 yards.
