Nikon offers the ability to get Spot On turrets to match that load you have made for your rifle to fine tune the BDC for different ranges. And with the .25 MOA adjustments that will let you dial it in to have it just where you want it to hit and the spring loaded turrets will hold there through rough shots or just bumps and bounces in travel.
