Moa Reticles

[overbore]

I know Nightforce sells both two an one minute reticles but I have no side by side comparisons for long range estimation to verify a LRF value or to get a range on a non reflective target. Any inputs?? Many thanks, Overbore

If you're referring to reticles like the NP-R2 with MOA hash marks, these are for hold-off, not range estimation.

They can also bw used for range estimation.... The fomular is as follows, target hieght in inches divided by the number of MOA time 100 equals distance, Example a target that is15" high and brackets at 2 MOA is 2 divided into 15 equals 7.5 times 100 equals 750 yards......

Except 15"/(2*1.047)"*100 = 716yds
The MOA would need to be normalized to inches.
How you gonna know 15" through a scope @ 750 anyway?

I know when I watch woodchucks as far out as ~600yds at 25x, they look like grizzly bears!

Sure it's possible to crudely range. But the MOA marks ARE for hold-off..

I used a number as an example...Mill recticles have been used for ranging for a long time and MOA reticles can be as well...Many who compete in tatical matches use thier reticles for ranging as some matches do not allow range findersor have non reflective targets.. I have used my reticle (MOA) in reverse many times to find out how large a target is after ranging it with LRF... I also use MOA not IPHY yards and it works just fine for ranging that way and that is exactly how Nighforce sugest it to be used...........

Absolutely, in fact the 1 MOA stadia will provide for .01 MOA interpolative ranging accuracy, and when combined with a high power scope will be one of the most accurate optical ranging devices short of a theodolite.

Any reticle with more than one stadia point in it can be applied as a rangefinding device, sometimes with remarkable accuracy (assuming u've guessed tgt. size accurately). Better than guessing, that's for sure!!

if night force says that you should divide by the amount of minutes then they must have made sure that the 1.047 value has been considered in the equation. can you test that it does not take into consideration that 1.047?
another point, i have been thought that range finding using reticles is usally accurate to about 5% by trained people. at 700 thats +/- 35yards. some cartidges might not be effected by this error. some might.
is the reticle in the 1st focal plain? im asking this because if it is not then the extra mag wont proof so beneficial.
