Rifle Scopes bushy 3200 tactical ranging

[jester1]

Guys sorry for such a simple question but I have searched and cant find anything including calling Bushnell themselves.

Ok Im new to shooting and purchased a 3200 tac 10X. Ive measured a known object at a distance and the result was approx 200 yards yet the object was way beyond that.

So using a 10x do you need to divde or multiply the answer to get the true distance? Or for example if a known object is 6ft tall and it takes up 10 mills that would be
6(12)*27.77/10=199.994

Thanks

Re: bushy 3200 tactical ranging

Your math is correct. There are really only 3 other variables that may be in question. Are you sure your target size was measured correctly, the subtensions are also correct, and the mil-reading was correct?

One of those 3 variables must be incorrect.

Make sure all of your units are the same measure. A mil subtends to 1/1000 its distance, in order for an object or distance to be measured they MUST be the same unit.

Remember,

1 mil = 1 mil anywhere
You can use an objects size as it relates to a mil and skip the conversion. Ie. The object is 3.5 mil at 100 yards...

1 mil =

3.6 inches at 3,600 inches
1 foot at 1,000 feet
1 meter at 1,000 meters
10 cm at 100 meters

Inches, feet and yards must be converted. You must do the same with metric but just move the decimal.

The formula for inches to yards for distance is:

Height of target (inches) divided by the amount of mils covering multiplied by 27.78 = distance in yards

Also, remember that 1 mil on a standard reticle is measured from the centers of two dots, not the side/edge where the dot meets the crosshairs. Standard mil reticle will have 10 mils from the rounded edge of outer duplex to its other side vertically and horizontally.

Hope that's helpful

That's a good point Bob-- here's one of the most helpful references for mil-ranging using the .2 round dot system--
