Illuminated Christmas tree reticle for FFP. The Christmas tree gives you fast hunting adjustment when you don't have time to twist the turrets and also for quick Kentucky windage adjustment for the second shot if required. For example, you see where the bullet impacted on your reticle in elevation and windage, move rifle to hold on that position in your scope reticle and fire again. Christmas tree gives you corrections for both elevation and wind or moving game. FFP is my preferred reticle for hunting and target shooting because the hold over for each line on the reticle doesn't change as you zoom, but due to the FFP fine cross hair at low magnification in low light, the illumination is a big help in low light or dark background.
