OK so here is the situation:
I need to know the number of clicks I need to turn my 1/4 moa scope that is zeroed for 100 yrds to hit a target at 500 yrds.
The chart I have says that I will be shooting 55.4 inches low or my come up in MOA is 10.6. I would also like to know how to calaculate this for other distances if I have the come ups in MOA.
Thanks
 
I'm sure someone on here can help you get close but you might want to provide some more information like what caliber you are shooting. Also keep in mind your barrel length, bullet weight, and muzzle velocity will be factors that will require you to do some fine tuning.
 
42 clicks unless I'M missing something?
Of course the chart is often just a reference and rifle/bullet/atmospheric conditions will have to be taken into account
 
Forget counting clicks. Your turrets have numbers 1, 2, 3, 4 etc. Those numbers mean something. If your turrets are 1/4 value then it will be 42.

This should help a little with the info you are looking for, what scope do you have, are turrets in moa or mils is the reticle in moa or mils. What caliber are you shooting etc. as some have said, you may need to provide some more info.
 
The only way you'll know is to go shoot. Turn the clicks up until the point of impact matches the crosshairs at whatever range you choose.... then write down the value in clicks/MOA/Mils or whatever the dial on your scope says. Go to the next distance, and repeat, and so on, and so on.....
Simple.

The ballistic calculators will get you close, but nothing works better than to actually shoot and then adjust for your gun, your bullet, your scope.
 
One should always work in MOA, not Clicks. Many different config scopes and sights and the only universal language is MOA. Of course you need to figure out how many clicks to the MOA that your sight has. If your sight has any sort of vernier learn how to read it so at any time you know where your sight is set instead of bottoming out and counting clicks back up!

A minute is 1 inch per 100 yards. So 55.5 inches is 10.5 minutes. The number of clicks would be 42, if it is a quarter minute scope.

If you have a target scope, lean to think in terms of minutes, not clicks. Make a note of the elevation you need at each distance.

The inside barrel (the part that does not move, has a series of level lines. Each line represents one full revolution of the turret. The turret has numbers (minutes).

I make a simple notation for each distance. It would look like 3-12 That would mean third line, 12 minutes. When I count the lines, the first line is Zero, like the first line on a ruler.
 
As others have stated a bit more info is required to answer the question is required.
Caliber, bullet weight, bullet type, at minimum is required.
Muzzle velocity helps but not 100% necessary.

A balistic calculator such as JMB, Strelok or others can be used.

Enter the info with a 100y zero and get your results.
If your drop at 500y is not accurate you can adjust the muzzle velocity till your 500y drop lines up or use the correction function to bring your 500y drop to where it should be.

The rest of your drops should line up.
By knowing 2 points on the curve the rest are fairly simple.

I am going by the assumption that all shooting will be done at the same altitude and similar barometric conditions.
Software can take into account atmospheric conditions but don't forget that garbage in = garbage out.

Edit to add: It just so happens that my 308 using 180gr SMK's with a MV of 2592fps. has a drop of 10.4" at 500y.
Mine is showing me .7moa at 200, 3.5moa 300, 6.7moa at 400, 14.5moa at 600.

Like others have recommended learn to use MOA how often do you count and miscount. Also you have stated what scope you're using, and of you zeroed the turrets. Zeroing the turret hash marks will make thinking in MOA easier.

This is exactly what I've done to make range charts for my 6.5X55 and 300 win mag (which are my most accurate rifles). Since I lack a chrono I've range verified 2 set points at 100 meters and 400 meters and used the JMB calculator to calculate the rest of the points at all other ranges and the eventual velocity of the ammo.
By playing with the velocity variable I was able to line up my known range verified set points and I'm assuming the set points at other ranges will be close.

My problem is that I don't have enough distance on my home range to verify the set points at distances beyond 400 meters so I'm wondering how close is close. Say if I ever had an opportunity to shoot at say 600 meters using my computer generated tables, would I be right on or maybe within 5 percent??
What are other shooters experiences with this?

P.S. Sorry if I've hijacked this thread but I think the posters here have already answered the OP questions very well.

I have a Chrony, and using a ballistic calculator, plug in the velocity and get the suggested rises from 300 (where I zero) to 1000 yards. When i take this new rifle to the range, we eventually shoot all the distances. I start each distance with the suggested elevation and have always been on paper. After the shoot I note the actual elevation used and eventually make up an elevation table to stick on the side of the rifle, based on actual elevations.

Your system would give a similar result, I expect. Close enough to be on paper ( a 6 foot square target, in my case).
 
Thanks for the reply, Ganderite, You seem to have a lot of experience at the game. So I get the drift from you that the generated set points are pretty general in nature. A 6'X6' target is pretty huge. That means that you may miss up to 3 feet on your first try. I guess I was hoping that the generated set points would be more exact than that.

I find it a bit disappointing that the ballistic trajectory of a particular bullet cannot be tracked closer than that, seeing as how the program makes a good job of including every possible known variable that can affect the bullet's trajectory. Possibly future ballistic programs will include more variables as they become known to us (better algorithms) and thus shooters could expect better first round accuracy.
 
Off topic I know but the thread title really surprised me. At a quick glance the c and the l side by side looked a lot like a d....
 
I think the main reason for not getting perfect results from ballistic calculators is poor input data. Weather conditions being the main one. Accurate atmospheric data is hard to get unless you have a loaded Kestrel model.
