Trying to figure mills

[Totosdad]

I have a 223 53 grain V Max loaded and Hornady say's at 500 yards it will drop

35.6 inches (not sure what my load will, just trying to figure this out).

Chart I read said at 500 yards 1 mill is 18 inches, if I held 2 mill high

would I be aproximately at 36 inches at impact, if my load will be

what Hornady say's?

Should tell you more than you want to know.

Is the scope you are using a mil or moa scope?

Yes

The elevation change of 1 mil = .001 x distance

At 500 yards 1 mil = .001 x 500 yds = .5 yds or 18 inches.
At 100 yards 1 mil = .001 x 100 yds = .1 yds or 3.6 inches

This is where it gets easy

At 726 yds 1 mil = .001 x 726 = .726 yds (or 26.14 inches. )

Thing is most of us don't know come ups in linear measurements, we just know them in mils or MOA for various distances.

With my 308s from a 100 yd zero, 200 yds = .5 mils, 600 yds = 4 mils

If you can actually learn to think in meters and cm it gets super easy.

If your zeroed at 200 yards, scope center 1.5" above center of bore and muzzle velocity of 3465. Shooting in no wind and elevation matches Hornady tests.

It is a Mill Reticle

OP - all things being equal, you are correct. If your bullet will drop 35.6 inches at 500 yards then dialing in 2 mils up elevation will compensate approximately 36 inches. Most milliradian scopes are 1/10 mil clicks. Your reticle may have 1/10 mil subdivisions.

100% spot on.

Just checking.

Mine is a 1/10

I just go here https://www.hornady.com/team-hornady/ballistic-calculators/#!/
And enter the numbers. Then print a dope sheet out and tape it to my stock.
Close enough for the Pdawgs I shoot at.

Shoot MOA's a lot less thinking and finer adjustments.

So are you suggesting he buy another scope?

 

[XTR]

This is really only true on NRA targets that are laid out in MOA rings. For that application I would strongly recommend MOA. Making adjustments that move you .3 MOA on a target face with .5 MOA ring spacing can get confusing. Personally, coaching a shooter with a mil scope on an F class target at 1000 yds can take an extra sighted or two to get where you want to be, but For pretty much every other application mils is easier once you get your head around it.

Yes, most mil scopes are 0.1 mil per click, and most MOA scopes are 0.25 MOA, the difference being about .110 inches at 100 yds, and 1.1 inches at 1000, if you can hold that you are really good. (Yes, many target scopes have 1/8 moa clicks, but there are also scopes with .05 mil clicks, same-same)

One real advantage of either is having the same adjustments as the guys you are shooting along side so when someone says “that was four and a half minutes of wind” or “I’m having to come up an extra two tenths today” you can use the info and not translate to another system.

Download a Ballistics app to your phone. It will provide the hold overs in all units. Strelok has a built in library for ammo to use as a starting point, and can use your actual shooting results for fine tuning.

Indeed. I prefer Mils but reluctantly went back to moa because it’s the convention in target shooting.

Mils are inherently dimensionless because they are just a ratio. Whatever distance unit you use is exactly your click value. If you’re at 250 meters, your 0.1 mil clicks are .025 meters, or 25mm.

The approximation of an moa as 1” per 100y will fail you as distances get longer.

As for coarseness of measurement, that is vastly overblown. I’ll spare you the statistics unless someone wants to see them, but basically only a short range BR shooter can realistically hope to shoot the difference between a 0.1 mil turret (0.36” at 100y) and 1/4 moa turret (0.26175” at 100y).

If you look at the statistics of std normal distributions and determining a true zero, you’ll come to appreciate just how difficult it is argue that 0.1 mil is too coarse.

 

[ToddKS]

The key is to stop thinking in terms of inches. Mils are mils. Use one of the many software programs out there to calculate your holds and then adjust according.

For one of my rifles my 600 yard adjustment is up 3.3 mils. I adjust my scope up 3.3 or on a holdover stage hold 3.3 up on the reticle. How many inches it is does not matter and only confuses an otherwise straightforward situation.

There is a major difference in the ability to center groups in the 1/2 moa x-ring at 300+ yards when shooting Fclass using 1/4 vs 1/8 moa adjustment capability. So it is rare to see anything but 1/8 in that application.

I have a 223 53 grain V Max loaded and Hornady say's at 500 yards it will drop

35.6 inches (not sure what my load will, just trying to figure this out).

what Hornady say's?

The unknown variable in this equation is the actual velocity of this ammunition in your setup, which may, or may not be close to Hornady's "box" value.

My suggestion would be to use one of the ballistic prediction algorithms as suggested above, but to also start out using some aiming point such as a rock, twig, broken piece of shotgun clay, etc., somewhere near the center of an area of dirt berm just behind and to one side of your target, if possible. The dirt splashes make it much easier to see the impacts. Otherwise, you can waste a lot of rounds trying to get on paper using ballistic predictions if the velocity is off from the "box" value, especially shooting relatively light 53 gr bullets at 500 yd. Alternatively, if you're going to be shooting on a large NRA-type target that will be marked by a scorer, you shouldn't have a problem.
