    can anyone tell be the difference in ballistics of the 150 grain .308 and the 168 grain .308? or tell me where i can get a trajectory table to learn the difference? the reason i ask is because i have a leupold mk 4 w/ a bullet drop dial marked for a 168 grain bullet....but i shoot a 150 grain.

    i would imagine that the dial would start to be inaccurate after about 300yds since a 168 grain drops faster than my 150 grain.

    or should i just use the dial with the marks that it has regardless of the different grain? is a 168 that much different than a 150 grain?

    any help would be great, thanks.

    Your Leupold has clicks that are probably 1 MOA (if it's a Mark 4 - M3 model). You can run the ballistics on any of the free ballistic calculators- I recommend JBM Online. You can always run the drop data directly and dial the corresponding MOA on the dial itself. The 150 will be a little bit off from 168, but both are probably somewhat off on your gun due to barrel and geometry differences.
