Rifle Scopes Useful mil dot numbers

[ARsR4ME]

Because there are alot of us that use mil dot and equivalents (tmr,mlr) out there how about a good list of things to take readings from in the real world.

Mailbox 8.5" high
Rims on duallys 17"
License plate 6"x12"
bricks on front of house?
concrete curb?
Stop sign?
Street sign?
Human head?
Average male height?
and so on

There was a thread with object sizes at one point. US DOT has a good PDF of standard road sign sizes.

Re: Useful mil dot numbers

Impact Data Books has a reference page available with a ton of objects listed with size.

Re: Useful mil dot numbers

My Log Book Page

YARDS
Object Size in Inches X 27.77 Divided by Number of Mil Dots = Yards to Target
METERS
Object Size in Inches X 25.4 Divided By Number of Mil Dots = Meters to Target

EXAMPLE
License Plate Size From Chart = 12" Width
License Plate Measures 1.75 Mil Dots Wide in your Scope
Calculation: (12" X 27.77) = 333.24 Divided By 1.75 Mil Dot = 190.42 Yards to Target


TABLE OF KNOWN OBJECTS
Head Width Front View 6.5"
Head Height Top to Bottom 10"
Chest Thickness Side 12"
Shoulder to Shoulder 20"
Pop/Beer Can 2.5" X 5"
License Plate 6" Ht X 12" W
Wheel Car & 1/2 Ton Pickup Add 1" to Est Tire Size
Wheel 3/4 & 1 Ton Add 1.5" to Tire Size
(Example F150 has 15" Wheel, Rim Outside to Outside is 16")
Brick 7.5" W X 2.25" H
Block 15.5" W X 7.75" H
Door Knob HT from Floor 36"
STD Door Height 80"
55 Gal Barrel 23" W X 34" HT
5 Gal Can 11" W X 13.5" H
IDPA Silhouette 31" HT X 18" W
IDPA Silhouette Head 6" HT X 6.75" W

This is my Police Chart.
For Military I would add common Military Vehicle & Equipment Measurments, Common Weapons Lengths, Helmet Height & Width, etc.

Figure out what you might encounter on your mission, and log the measurments. That simple.

Re: Useful mil dot numbers

Thats the stuff Viper. I thought there would be more intrest in such things but maybe people already have the measurement. Thanks for the numbers.

That's great for an MOA scope, but what about for us mil guys?

Please Explain.
You should have some form of Mil Ranging Scale in your scope.
Take a reading on a known size object's size in Mil's (This works the same with Round Mil Dots, Oval USMC Mil Dots, Gen II Mil Dots, TMR Tic Marks, or any other set up based on the Mil Scale.)
Do the math, and you have the range.

At this point you can Dial in the MOA correction from your Log Book Chart, Dial in the MIL Elevation in a Mil/Mil scope from your Log Book Chart, Hold Over in Mil's also from your Log Book Chart, or just dial in the Yardage/ or Meters on a scope with the yards or meters on the Elevation Knob.

If the Question was about the Military Known Objects list. I have never put that list together so far. We run about 10 LE guys through our Sniper Class to 1 Military. I just have never took the time to research out a Military Known Objects List. I probably should geterate that Log Book Page. The youngest Boy is headed to Afganistan or just got in Country. I may have him try and get some measurments together.

Re: Useful mil dot numbers

Bro-- It's called a JOKE! There has been quite an erroneous trend that MOA= English Measurements and MIL= Metric. I was just fooling around...

Re: Useful mil dot numbers

The best "optics stds." (for practice) I've ever had were right out the window of my house. While researching reticle rangefinding with 2nd focal plane ballistic and rangefinding reticles, i just lasered and measured every sign out to 1000 yds. right down the street in front of my house. Had about 10 stds. to play with then.....as discreetly as possible, of course.

Learned many things from these stds. One of the most important was that "mil-ranging" (and the mil-ranging formula) is not specific to the mil-dot but can be used with any 2 points at one distance relative to any 2 points at another unknown distance (from simple plex to Ballistic Plex to archery sight pins to iron sights on a pistol). This concept is way bigger than the milliradian itself.

Also taught me that the mil-ranging formula in it's most basic form defines not only rangefinding but also downrange zeroing with any reticle or turret system.

thanks for them formulas, it was very helpful and i now understand, i was beating myself up untill i found this.

Re: Useful mil dot numbers

I took this data and made an Excell spreadsheet that does the math for you.

So far I've only inputed the data from this thread. Anyone who know Excell is free to add their own data or do with this what they like.

I dont know if an Ipod/phone has an excell app, but if it does when I get one I'll plan on updateing this spreadsheet alot to make ranging alot faster.
