ok you have 56 MOA of elevation, range is 600 yards, trajectory is -58" so, lets do this
58" / 1.047 (moa)/6 (range in hundreds of yards) = MOA elevation needed
58"/1.047= 55.4 (rounded up slightly) 55.4/6=9.23

So it would take 9.25 MOA (37 1/4 moa clicks) to make zero at 600 if your -58" low, each click would move your point of impact 1.57" (1.047/4= .26175x6=1.5705") at 600 yards (1.57x37= 58.09"), so yes 56 MOA of elevation is plenty to make a 600 yard zero.

Remember you not just raising the bullet, your changing the bullets angle of departure so the POI is going to move more as the range increases. so those 56 MOA of adjustment will change the POI 351" at 600 yards if you turn the scope all the way up.

All right, my ignorance is coming through again. Thanks for all the replies, it answered a lot of questions however now I have one more. After doing the math I need to adjust for 9 moa. Now that equals say 37 "clicks", what does the 0-14 mean on my target turrets. Is there a book or website I can go to so I stop waisting your guy's time.......

You've never said what scope you have or are using for reference but some scopes have 10 moa (or ") per revolution of the turret and some have 15 per revolution. You can't show the zero as well as the 15 so it reads from 0-14, 15 would be one full turn stopping on the zero. If you scope is designed using moa then each full number on the turret would be 1 moa increment. You should have 4 small marks between each full number. They are 1/4 moa adjustments.

There is a good website where you can get information. And......you are there.;);)

Usually it's one number per MOA --- if you know what your click values are, you should be able to verify this on the scope.

For example, if you know your scope has 1/4 MOA clicks, then it should take 4 clicks to go from the hash marked '0' to the hash marked '1' on your turret.

Note that the 0-14 markings are only correct on the first turret rotation -- so if you had to do 16 MOA, then you'd have to do a complete rotation of the turret, and then 8 more clicks (so you would end up on the hash marked '2', but you'd be adjusted for 16 MOA of elevation). Just make sure you don't lost track of what rotation your turret is on.

Edit: Oh yeah, what Dick said -- back around to zero again would probably be 15 MOA, so if you dialed around to 16 MOA, you'd probably end up on '1'. But yeah, depends on your scope.

There should only be three smaller marks! 1/4, 1/2, 3/4
Just to clarify, carry on!

This comes up so often we need a sticky or a tech article.
I think the hardest thing for newby's is that MOA is an angular term.
They want to give it a mesurement/size that they can relate to when in fact it "is" the mesurement, "Minute-Of-Angle"

MOA= 1.047 inches only at exactly 100 yards!!
MOA= 10.47 inches only at exactly 1000 yards.
MOA= .01047 inches at three feet or one yard!
It is a very small angle it is 1/60 of one deg.

:oGood catch. My brain knew what I was thinking but my fingers get a little carried away some times.

I just got a Leupold VX-III 6.5x20 L/R Target. Its going on a Rem. 700 that was just converted to a 300 Dakota. The scope has the large target knobs that read from 0 to 14. You are right, if you were to count, going back around to zero that is actually 15. Now with everyone talking about clicks and adjustments, if I needed to go to 9moa to adjust for drop at the given yardage do I need to count the 37 clicks or just turn the knob until I get to 9. It should be just the same yes no. This is whats confusing me.
