Mildot Master for sub-mil ranging

[Lexington]

I knee-jerked a purchase of a Mildot Master so I could stop taking my vintage HP-11C calculator to the range. It looks like the ranging begins at anything that subtends 1.0 mil, but nothing less. I tried to line up 24" at 0.7 mils and - piss - nothing.

Am I missing something, or did Mildot Master never expect anyone to shoot a 24" target 952 yards away?

EDIT: What? Read the manual? No way! (OK, I found the answer in there.) I have time to post here but not read the manual first. Duh.

.666*1000/.7=950 (951.4 to be exact)

Who needs a mil dot master. Fun to play with but more crap to carry and loose.

Learning has occurred, glad you found out the answer. The Mildot Master is a great tool that goes beyond simply being able to range things.

I can, and have, derived the ranging formulas, but I do find a calculator or a Mildot Master to be handy. I also use an FDAC as a crutch so I don't have to memorize that data, either.

IMHO, MilDotMaster is one of those pieces of kit that everyone should have and learn to use.

Even if you end up running an LRF, etc. knowing how to run it is a critical skill. It was 'day one' for us at my first school. And we ran them endlessly. No LRF's allowed.

Even if you don't take it in the field (mine is tucked in the back of my data book), just knowing how to run one makes the process of milling a target more intuitive, more understandable and clearer. They work brilliantly and can do a lot of interesting 'stuff.' Not to mention batteries fail, sliderules do not.

Do I use mine much any more? Nope. Mostly use LRF. But a few weeks ago we got a rare opportunity to get out on an 800 yd range with a lot of unknown distance targets and my LRF was out-classed. Out came the MDM.

There are a couple of videos on YouTube about using MDM... and I would guess that Lowlight has an online course on MilDot Master and it's probably worth taking. A good instructor can show you how to get a lot out of a MDM.

Cheers,

MDM and Mil/MOA Subtention Tables [1/10 or 1/100 Mil Subtententions -vs- Target Sizes ] for ranging are excellent "analog" tools. Similarly, FDAC and XR-MILPSEC FDAC are complementary "analog" tools for Elev/Wind/Mover data.

@ kraigWY - Understand that the range can easily be calculated via "digital" tools (e.g. calculator). Easy day. And like Lexington, have derived the formulas backwards/forwards. Simple math/trig. Do not want to use a calulator to determine a Range.

Laminated Subtention Tables allow shooters to quickly compare RANGES, obtained via milling the target's height and width dimensions, for any significant deviations/errors. Example: 8" x 14" target subtending 0.28 mRad in width (779 yds) and subtending 0.50 mRad or 0.48 mRad in height (764 yds, 795 yds) are in close agreement. Perhaps the width measurement was 100% clear, while the height measurement was sketchy? Perhaps re-milling results in a 0.49 mRad height? "Seeing" the range variations tabulated sure beats back-n-forth "digital" calculator troubleshooting. Time savings? Maybe, maybe not. It's the principle.

FWIW, LL posted a 1/10th Mil Relation Chart, built by www.shootingvoodoo.com, in a related thread. The Chart is exactly what is refenced above.

Re: Mildot Master for sub-mil ranging

So I take it you found the right hand side which can be used in mils to break down to .3 or MOA?

Yes, indeed.
