Rifle Scopes falcon menace range verification

[Dracozny]

the other day I went to verify the mil lines on my falcon menace 4-14x44 with B20 reticle to Range. I only had about 7 yards in the house that I could measure accurately but I discovered that the scope after computing the math said it was 7.4 yards. from the mil-dot.com site the equation is basically (as many of you know)
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>Object size (in) x 27.77 divided by mils read</pre></div></div>
after playing around with the numbers in excel I found that for this particular scope the equation is
<div class="ubbcode-block"><div class="ubbcode-header">Code:</div><div class="ubbcode-body ubbcode-pre" ><pre>Object size (in) x 26.25 divided by mils read</pre></div></div>
anyone else with a falcon notice such a deviation?

Don't have a falcon but I know that the 'standard' equation for mil range estimation is simplified so that it is easier to do an estimation quickly. The difference in estimation to actual is minuscule until you get out to longer distances. But when you get out that far it is probably best to have a laser ranger finder.

Reading your hash marks exactly is rather a chore.
Were you using center to center or the bottom of one to the bottom of the other? (or top to top)

in this particular case I used a tape measure stretched out sitting at 7 yards so it equaled 15 mils exactly since the tape measure was standing I went top to bottom, the bottom sitting right on the 4" line.

Re: falcon menace range verification

If you measured from the "outside" of the bottom hash mark to the "outside" of the top hash mark, you introduced an additional .07 mrad to the equation (approximately).

ok I will recheck it in a few

I would want to train myself to do it without a laser range finder. just a personal preference for the case where battery powered devices are not an option for one reason or another.

Don't get to wrapped around the axle about it being "perfect".
You are not going to know the EXACT size of your target anyway.

It is a good system, but inexact as the difference in target size, inexact subtension on the target etc...

Re: falcon menace range verification

well after checking again, adding in an extra yard and using a sturdier rest, I came to the conclusion I must have just read it wrong last time. its not exact but I came within inches instead of feet. it will just take some practice.

Unless you are milling really big targets is border like useless.

If you mil a 12" target and give it a .3 mil call it's 1111. If you see it as .4 it's 833.
Let's say your good enough to call it .35 it's 952.

My point is most of time with a solid rest and a nice retice such as the G2 we can determine .x In some cases may even be able to get a .xx call I know there is no way i can call a .xxx call Just .025 either way is right at about 150 yards. If your shooting at a 12" plate your mill call would HAVE to be .xxx acurate.


Personally I don't mil things (such as plates)very often at all because I can normally guess within a couple hundred yards inside a grand. Lol.
