Using a mil dot scope with 1/4 moa clicks - please help

I'm shooting my .308 with a mil dot scope fixed 10X power and the turrets adjust in 1/4 moa clicks.

I would like to know how I aim for a 1000 yard target. As far as I can tell my bullet would drop about 367 inches or 10.19 mils. To bring the bullet up to the middle of the crosshairs (or move the crosshairs down to the POI) I would have to adjust the scope for 367 inches or 1,468 clicks which I don't think my scope can do. To use the bottom post I would still have to move the turret 734 clicks.

What am I missing?
 
What you are missing is the angular unit of measurement and applying it to the drop or dope of the given load. The chart here shows that 1 moa is about 10.5” at 1000y.

If your estimate is that you need 367” of elevation , divide by 10.5 for the moa required. 367/10.5=34.95moa which is a reasonable assumption for a .308 at 1000 y with a 100 ish yard zero.

This is around 140 “clicks” but try to start replacing clicks with Moa or Minutes of Angle is speak and writing, it will help you absorb the information of the terminology is accurate.

I suggest watching the sniper 101 series on YouTube by Rex reviews. Excellent information for all levels, even brand spanking new LR shooters. Start on episode 1 or look through his library for specific topics.
 
If your scope is calibrated in MoA, forget about mils.
Use the calibrations on your scope's dials, don't count clicks.
Once confirmed, record your elevations in MoA. If your base zero is at 100y, slip your scale to "0" for that distance. Similarly, zero your windage scale.
If you set up a tall target at 100 with a vertical line drawn running up from the aiming mark; wind up your elevations, and see if your shots are falling on or close to the line all the way up to the 35 minutes of elevation suggested for a starting 1000y zero.
Tables and apps are all very well, but it is ultimately your rifle and ammunition that will tell you what your "come ups" are.
 
whatever app you are using, change the value to MOA. That number is then easily applied to scope adjustment - turret movement

App suggests 32 MOA of UP... dial 32 numbers (4 clicks per number) from your 100yds zero,, send it and adjust as necessary.

I have the same type of scope Mil reticle MOA turrets

1MIL = 3.43 MOA
I treat distance in MOA and adjust my elevation based on my ballistic program which is set up to read MOA.
- Your turret tells you how may MOA are in one full revolution
Mine is 12moa per turn, using 32moa as our example from 100 to 1000 would require TWO full revolutions (24) plus an additional 8 MOA. Your scope has hash marks for each full turn of your turret as additional reference. Take a pic of your 100 yard setting and dial 32 MOA take a 2nd pic compare the two
Windage is a combination i dial using MOA but have a MIL reference in my reticle, using the reference 1MIL = 3.43 MOA i can see how far away from centre my shot is and can adjust accordingly

Fine if you can dial the reticle center far enough to match the moa needed
trouble starts when you want to hold over on the reticle, keep in mind the value of each mark in moa equivalent
 
The repeatability of adjustment at the extremes of the screw thread come to mind. The scope was designed to be set with the reticle near the middle of the optic and with the screws more of less even. Cranking the knob up will move the crosshairs, but is that adding an instability inside the turret? I'm smart at some things, but the innards of telescopes are beyond me. My thought would be to angle the base enough so the telescope is not a stressed component in your accuracy equation.

I have two experiences which bear repeating. First was a cheap Tasco 3-9x32 scope broke under recoil when mounted on my .300WM. No matter how careful I was, the reticle danced inside the tube and would not get and stay on zero. Second was I got a sloped scope base for a Model 700. When installed the reticle of a nice Bushnell did not have enough travel to come on paper at 200yds. That was the longest distance available for zeroing, and the rifle would hit under the target with the knobs turned down. It probably would have been centred at 600yds, but I didn't have the opportunity to try.

Does the scope your using have a target turret with MOA calibration ?? if you go to the Hornady site and click on calculators on the top bar then input the ballistics of your cartridge hit calculate it will give you the bullet drop and adjustment in both MIL and MOA you will quickly understand the correlation between inches of drop and MOA adjustment needed, you will also see the difference between MOA and MIL. I have 2 Nightforce scopes that are in MOA and a Bushnell tactical LRS that is in MIL and the charts I use are specific to each so I don't get messed up, but to understand the difference print the sheet with both MOA and MIL factors.
Good luck and burn some gun powder.
 
Don't even bother thinking about inches or other forms of linear measurement.

Think and work in MOA. Put your data into a ballistics calculator, with MOA as an output. Your reticle is a ruler, use it as such.

Put your inputs into the calculator, get your outputs. Dial your scope the corresponding amount of MOA as the calculator says for the target distance at the given environmental conditions. Take a shot, and spot the impact. Measure where the projectile went in referenced to where you aimed, and measure with the reticle how far off it is (if any). Make corresponding MOA adjustment.
