If you know where you will hunt and the most likely distance to your target, go to the range and place a target at that distance. Zero the scope on that target.
Move the target half the distance toward your shooting point, take a shot and record the amount of drop/rise from zero at that distance.
Move the target out that same distance past the original target (zero) point, take a shot and record the amount of drop/rise from zero at that distance..
You now have some shooting practice with your rifle and new scope and you know the ballistic characteristics at three sensible distances as based on your hunt plan.
You are a hunter - use that data - figure it out.
Or, read all of the above posts, consult the online data charts as applicable to your cartridge, and proceed as you would have done before you saw this post.
Hope this helps.
