TreblePlink Posted February 26, 2015 Share Posted February 26, 2015 Hi folks, been shooting pistol for a while, and now learning rifle ... According to Wikipedia, the Angular Mil is not always 1 MRAD or 1 / 1000 of a radian, but sometimes rounded, such as the 6400 per circle in NATO countries. (Ibid) The exact MRAD unit is 2 PI * 1000 per circle. As far as scope elevation adjustments and reticule Mil-Dots are concerned, do most scope manufacturers honor the exact 6283 unit or the fudged unit?

ChuckS Posted February 27, 2015 Share Posted February 27, 2015 Just yanking your chain. Mostly because your question stumped me. From Merriam-Webster: reticule noun ret·i·cule \ˈre-ti-ˌkyül\ Definition of RETICULE1 : reticle 2 : a woman's drawstring bag used especially as a carryall reticle noun ret·i·cle \ˈre-ti-kəl\ Definition of RETICLE: a scale on transparent material (as in an optical instrument) used especially for measuring or aiming It looks like the spelling is interchangeable...

magpulled Posted February 27, 2015 Share Posted February 27, 2015 I'd go mils. Just preference for me though. Check out tebosauras Rex on YouTube. He's got some really good videos on LR rifles Link to comment Share on other sites More sharing options...
TreblePlink Posted February 27, 2015 Author Share Posted February 27, 2015 The problem I have are all the various references to Mil-Dots, MILS, MRADS, - as if the unit is interchangeable. Certainly it's close, but are all these units in the US really Milli Radians, or the Nato version? I would just like to avoid rounding errors where I can - got enough other variables going ...

striped1 Posted February 27, 2015 Share Posted February 27, 2015 I would contact Vortex or whichever manufacturer you are interested in and ask. Vortex is very easy to contact and run tech questions by Link to comment Share on other sites More sharing options...
gdboytyler Posted February 28, 2015 Share Posted February 28, 2015 I think you are over-thinking the issue. If 1 mil on your scope measures 36" at 1000 yards or 3.6" at 100 yards then don't worry about it. Otherwise, you got a bad scope. Link to comment Share on other sites More sharing options...
427Cobra Posted March 2, 2015 Share Posted March 2, 2015 6400 is for artillery, 99.9% of the scopes are 6283 mils, the reason artillery uses 6400 is because it's divisible by 8, and close enough kills just fine with artillery, with precision rifles they all use 6283, only a old a Leupold used 6400. Someone will come along, or yall will read on the Internet how much POI (point of impact) .1mrad is at 100 whatever, DO NOT convert angular measurements into hard values, 1 Mil is 1 mil, and 1 moa is 1 moa, use the reticle as your ruler, and don't ever buy a scope with a Mil reticle and MOA knobs Link to comment Share on other sites More sharing options...
Wild Gene Posted March 8, 2015 Share Posted March 8, 2015 This is why I use MOA! Link to comment Share on other sites More sharing options...
ShooterSteve Posted March 9, 2015 Share Posted March 9, 2015 It really doesn't matter. They work about the same as long as you learn your system and run with it. Link to comment Share on other sites More sharing options...
Stlhead Posted March 10, 2015 Share Posted March 10, 2015 I want a liter of cola please. What you only sell it by the quart? what should I do, I am thirsty, but I want a liter, not a quart. Link to comment Share on other sites More sharing options...
rhett45acp Posted March 10, 2015 Share Posted March 10, 2015 I read this paper - more than once. A lot of lightbulbs went off in my head. MILS and MOA - Mil-Dot Also check out Brian Litz on the interwebs. Super cool dude. If you follow his works you will quickly realize no scope comes "correct". In one of his videos he explains how to calibrate a scope to your junk. Then once calibrated you shoot your "system". Learning the above paid me back in spades.

Wild Gene Posted March 10, 2015 Share Posted March 10, 2015 I take back my first statement. It should be "I chose MOA because people make the whole thing more complicated than it is". The difference between the two is the name and the number of units used to measure a given space at a given distance. To break this down into much more just confuses it. When you threw out that 6,400 and 6,283 or whatever they were, I am going out on a limb here, the difference between the two numbers is probably well beyond the accuracy capability of a rifle and only necessary to calculate something like landing a space vehicle on a specific crater on Uranus. It would be (please correct my math, I'm winging it here) less than 2% difference. At 1,000 yards, that would increase a 5" group to 5.1". Gentlemen, I am certain you will correct me if that is incorrect. wg Link to comment Share on other sites More sharing options...
gdboytyler Posted March 10, 2015 Share Posted March 10, 2015 (edited) Bored at work, so I calculated the theoretical difference for a scope based on the different definitions for "mill". I calculated the drop based on the actual trig function. See attached table. Edited March 10, 2015 by gdboytyler Link to comment Share on other sites More sharing options...
Rob01 Posted March 10, 2015 Share Posted March 10, 2015 (edited) Way too much being read into this. You buy a mil scope then you run your data in mils. And scopes do come correct. You should be checking the tracking of a new scope. If it is off you should know but I have had plenty that are right on.

Wild Gene Posted November 3, 2015 Share Posted November 3, 2015 OK, I take it all back, I switched over to MRAD for long range.... It is really nice to work with. Very easy ranging capability. What Rob01 said Link to comment Share on other sites More sharing options...
