Re: Teleskoop spesifikasie voorkeuse???
The Mil system was originally adopted in the current NATO form by the French as an alternate to decigrades as the primary unit of measure to sight field artillery shortly after World War I. It was shortly after that time that the United States adopted it for the same purpose. The push for a standardized unit of measure among NATO forces lead the charge during this time period and is the primary reason for adoption of the metric system by the United States military and allied forces. With this being the case, it is often thought that the angular mil is a metric measurement. This is a false but understandable assumption considering the consequential linear associations, as you will see in a moment. While it may be insignificant, it holds true that the mil system is not metric, nor imperial, but an angular unit of measure just as MOA and IPHY.
One mil is 1/6400th of a circle. Just as with the MOA system, which is broken down from 360 degrees of a circle, the mil system is based on 6400 mils in a complete circle. The actual number of mils in a circle can be somewhat confusing due to the fact that different countries claim different numbers. NATO countries recognize that there are 6400 mils in a circle. The actual trigonometric measurement calls for 6283 mils in a circle. Non-NATO countries have even different interpretations. It is up to you which interpretation you want to adopt, but personally, I will side with the U.S. military! Thus, for our purposes we will contend that there are 6400 mils in a circle.
The linear distance covered by one mil is identical in its behavior to MOA and IPHY in that it increases as the distance to the target increases. In the illustration below, you can see that one mil covers 3.6" at 100yds and 7.2" at 200yds. This behavior is true of all angular units of measure.
Image
As you can see, one mil covers more than three times the linear distance than one MOA does. This results in much smaller mil numbers to gain an equal adjustment that a larger MOA number provides. For instance, we discussed that for a typical short-barreled 308win to reach 1000yds that approximately 42 MOA of adjustment would be required when using 175gr bullets. To reach that same distance with an identical trajectory would take 12.2 mils of adjustment. These numbers are simply estimates to show the differences between the two units. Real world drop will be different for every load and rifle combination, so proper application of a ballistic computer should be employed to get your exact drop. We will cover ballistic computers in a future article on Primal Rights.
Image
Optics manufacturers seem to be much more standardized when it comes to the mil system when compared to MOA. Typically, most mil-based rifle scopes are set up with 1/10th click turrets. This means for every click of the turret you will adjust for 0.1 or one tenth of a mil. This translates to a linear difference of 0.36" at 100yds or about 1/3 of an inch. This is slightly more coarse than the 0.25" typical adjustment of MOA turrets and vastly more coarse than 1/8 MOA clicks. That being said, I have not encountered a single situation in a match, hunting, pounding steel, or target shooting where the 0.1 mil clicks were not precise enough to make the adjustment required to hit the target. One click at 1000yds translates into a 3.6" linear adjustment. That is pretty small.
The reticles offered by most companies are also somewhat standardized. The various different mil reticles carry different names for the type of reticle they represent, as well as specific names given to them by their manufacturers. The original mil-dot reticle is as you see below. The measurements of the reticle are what is referred to as "sub-tensions" which is simply a description of how the reticle is laid out. You can see that the dots cover a 0.2 mil area, and there is a 0.8 mil space between each dot. This style of reticle is referred to as a standard mil-dot.

Moet nie alles glo wat jy op die internet lees nie!!! 
Die stelsel is desimaal en die eenheid wat gebruik word is Mil.
Reg of verkeerd?

Re: Teleskoop spesifikasie voorkeuse???
Ludwig, lyk my ons mis mekaar iewers, miskien n geval van 6 van die een en 1/2 dosyn van die ander. 1 mil bly op enige afstand 1 mil maar die linere waarde daarvan op die teiken (metric om dit makliker te maak) verskil per definisie. die hoek verander nie maar wel die waarde op n gegewe afstand. 1 mil op 100m = 10cm en 1 mil op 1000m = 100cm. Die linere afstand na die teiken is wat ons deurmekaar maak.
Soos Rocketman op n ander forum se:
Actually, radians aren't technically unitless - one radian is equal to the radius of the arc you're describing. In other words, they are a unit that transcends inches or mm by simply relating the arc length of an angle to the radius of the arc. Hence, 2*pi radians (a little over 6) gives you the whole arc of a circle.
http://upload.wikimedia.org/wikipedia/c ... _color.svg
This is convenient because if you know the width of a 1 foot target in your scope is 1 milliradian, for example, you know that the distance to that target is 1 radian, or 1000 feet (333 yards). Without changing anything, you could say just the same that a one meter target that takes up 1 mil would be 1000 meters away. Its usefulness may be diminished with the presence of a high quality laser rangefinder, but it is what it is.
Mil (or Mrad) is actually extremely simple!
Radian refers to an arc the same length as the radius of a circle where the shooter is in the center of this circle, and Milli is 1/1000.
If you hit one Mil left of where you aimed, that simply translates to a point of impact that shifts left 1/1000 of the distance to the target.
It doesn't matter if you use meters, yards, feet or inches. However, since the metric system is based on increments of 10, it can feel a little bit easier to work with.

To summarize what has been said so far...
I fully realize that we may not have succeeded in answering all your questions.
Indeed, I feel we have not answered any of them completely.
In fact, the answers we have given only serve to raise a whole new set of questions, some of which we weren't even aware of previously.
To sum it up - in some ways, I feel we are as confused about things as ever.
But, I believe we are confused at a higher level about much more important things.

Re: Teleskoop spesifikasie voorkeuse???
My laaste 2 cent. So effens tong in die kies - kom doen n Precision Rifle kursus (3dae) by ons (SOC Survival Training) en sien hoe maklik dit eintlik is.... Rangefinders en windmeters is daar om te bevestig of ons reg lees ... Ons fokus is op "marksmanship" en nie op hoeveel geld jy kon spandeer op battery aangedrewe katoeters. Ons gebruik dit wel om die DataOfPreviousEngagements DOPE optestel en dan is die volgende waar ......." range is not a problem but the wind... well that can make the shot interesting.... tot dan, moenie die skoot maak gebeur nie, laat dit gebeur.
Hier is n tipiese toepassing soos op ons kursus:
The most asked question these days seems to be, "What is the advantage to Mil turrets and a matching Mil reticle?" Lets think about our normal shooting situation. You sight in on your target at 400 yards. You apply the fundamentals of marksmanship and fire your shot. You see the impact is 6" low. Now since you are 400 yards away divide 6" by 4. You end up with 1.5. Now you need to come up 1.5 MOA (approximate) so that's going to be six clicks on your 1/4 MOA scope. You dial in the correction and fire. Now you hit your target. That's not too bad. It's a little math, but nothing we can't do in our head without coming off the rifle.
Now lets consider that you are on the same 400 yard line and this time your shot hits low again with your other rifle. This scope is equipped with a Mildot reticle and 0.1 Mil turrets. You observed that the impact was .5 mil low. You reach up, dial five clicks up on your elevation. The next shot is dead on. This is convinient, but not earth shattering.
Now lets move away from the KD range and all of it's neat yard lines and paper targets. Lets imagine we are on a hill out in the middle of nowhere. About 660 yards away you have a torso sized steel plate. You estimate the range and dial in your dope. You make your wind call, breath, aim, stop, squeeze and followthrough. You see the slash of the round in the dirt in front of your target. In your reticle you can see that you were 1 mil low. You dial ten clicks up on your 0.1 mil turret and re-engage or hold 1 mil up and re-engage. This time you see the puff of the bullet disintigrating on the plate and then the satisfying "clank" echo back to you.
It was quick and easy. If you weren't using a mil reticle and mil turrets your math could have thrown you off if you weren't very close on your range estimation. If you got flustered because of a time limit your cognitive process could go fly out of the window.
En met hierdie kort definisies sluit ek af:
MOA Defined.
MOA is an acronym for "Minute of Angle". This is an angular measure. There are 60 minutes to a degree and 21,600 minutes to a complete circle. Now that I have told you that, you can purge it from your memory because it really doesn't matter to us. What does matter to us, is that at 100 yards a "Minute of Angle" equals 1.047 inches. At 200 it equals 2.094". At 300 it's 3.141" and so on. Simply multiply 1.047 times the range in hundreds of yards.
MILs Defined.
Mil is short for milliradian. There are 6,283.19 milliradians to a circle. One mil equals ten centimeters at 100 meters. This is where the confusion frequently starts. There is nothing Metric about Milliradians. The angles just work so that it appears that way. One Mil equals 1 inch at 1000 inches, 1 yard at 1000 yards, 1mm at 100cm, etc. Notice it works with metric measurements as well as with the imperial system.

Re: Teleskoop spesifikasie voorkeuse???
Kom ons draai nou nie doekies om nie. Almal behoort teen die tyd te weet dat 1 milliradiaal 'n verhouding (hoek) van 1:1000 aandui. Dis basiese kennis, niks om oor te stry nie.jjmare wrote:My laaste 2 cent

Wat wel vir langafstand-skiet relevant is, is dat niemand wat in duime, jaarts en gelling werk, sy skiet-berekeninge in mils doen nie. MOA pas beter by die ingelse stelsel.
Die van ons wat met die metrieke stelsel kan werk, werk baie lekkerder in mils, omdat dit intuitief is. Die som werk so: 1 Mil is 100mm op 100m, of dan 1000mm op 1000m. Die verhouding van 1:1000 is presies die verhouding tussen mm en m. Daarom werk ons met teikens in mm en afstand in m. Maklik, geen ingewikkelde somme en konstantes nie.
Niemand meet skiet-afstande in duime nie, anders sou mils ook met duime kon gewerk het. As jy afstande in jaart meet en die teiken in duime, dan is MOA baie makliker, want 1 MOA = 1,047" op 100jaart. Dit word afgerond na 1" en dit werk ook lekker maklik.
Dus, niemand (behoort te) dink MOA is imperiaal, of Mils is metriek nie, dit werk net baie lekker saam vir skiet-doeleindes.

Re: Teleskoop spesifikasie voorkeuse???
Soos reeds hierbo genoem gaan ek nie te veel ingaan op die verskille tussen MOA en Mils nie.
Net die volgende vanuit my hoekie:
1. Ons gebruik metrieke stelsel vir alles in RSA - dis hoe jy in skool opgelei is. Ek dink in mm, cm, m, en km. Dis vir my baie eenvoudiger om dus in Mils te werk. Ouer jagters/skieters het grootgeword in MOA milieu en dis waaraan hulle gewoond is.
2. Die argument van kruis wat dikker word in FFP scope dra nie baie water vir my nie. Dit hang baie af van watter tipe retikel van watter vervaardiger jy gebruik. Ek het Schmidt Bender PMII scope FFP met P4L Fein kruishaar en kan nie sê dat die dikte van die retikel op maks vergroting op afstande van 100 - 1300m al ooit 'n probleem was nie...
3. Dit is wel so dat 1/4 MOA fyner kan stel as 0.1Mrad clicks, maar soos reeds hierbo genoem is daar maar min skuts wat daardie verskil kan agterkom met hulle skietvernuf op 1000m (ek sluit myself hierby in...).
Vir my is die ideale langafstand scope die volgende:
1. 4-16 of 5-25 vergroting.
2. 34mm of dikker main tube diameter.
3. FFP
4. Reticle en Kruis in dieselfde eenheid (duuuhhhh)!
5. Milrad verstelling 0.1 MRad clicks.
6. Double Turn Turret.
7. Parallaks verstelling.
8. Fyn genoeg reticle bv. Schmidt Bender P4 Fein of Horus H37 ens.
9. Koop goeie glas - jy kan nie dieselfde verwag van 'n R15 000 scope met bg as met 'n R50 000 se scope nie.

Re: Teleskoop spesifikasie voorkeuse???
Om terug te kom na die oorspronklike vraag.
Gegewe die kaliber sal sy maks effektiewe skietafstand omtrent (raak subsonies) 1200m wees. Kom ons neem die volgende tipiese ballistiese tabel as voorbeeld:
123 6.5x47 Lapua @ 2930
Zero 100yd 5000' Density Altitude
RANGE ELEV- moa mil | WIND(10) moa mil RANGE
100 0" 0.00 0.0mil | 0" 0.50 0.1mil 100
200 2" 1.25 0.3mil | 2" 1.00 0.3mil 200
300 10" 3.25 0.9mil | 4" 1.50 0.4mil 300
400 23" 5.50 1.6mil | 8" 2.00 0.6mil 400
500 42" 8.00 2.3mil | 13" 2.50 0.7mil 500
600 68" 10.75 3.2mil | 19" 3.00 0.9mil 600
700 102" 14.00 4.0mil | 27" 3.75 1.1mil 700
800 145" 17.25 5.0mil | 36" 4.25 1.2mil 800
900 197" 21.00 6.1mil | 47" 5.00 1.4mil 900
1000 260" 24.75 7.2mil | 59" 5.75 1.6mil 1000
1. Dan het jy 25MOA / 7.2mil nodig vir elevasie met n 100yd zero op 1000yd. Jy benodig n teleskoop met ten minste 50 MOA elevasie verstelling as jy n "zero slope" basis gaan gebruik. Kies verseker n 30mm of groter main tube.
2. Wat jy verkies MOA of Mil maak nie regtig saak nie en is n persoonlike keuse. Ek sal egter mil kies.
3. Soos genoem is die belangrikste dat die reticule en turret verstellings in dieselfde eenheid moet wees.
4. Kies n kruisdraad wat vir jou gaan werk - hou jy bv van die "besige" kersfeesboom tipes met wind en elevasie afmikpunte of soek jy n "skoon" tipe soos n Gen 2 Mildot. Maak net seker dat as jy die reticle wil gebruik vir afstand bepaal dat hy hom daartoe verleen.
5. As jy die regte kruisdraad kies gaan jy geen fout maak om n FFP teleskoop te kies nie. DIt maak alles net soveel makliker (lees vinniger)
6. Kies die beste basisse wat jy kan bekostig - verkieslik n eenstuk picatinny tipe en as nodig 20MOA sloped.
7. Kies die beste ringe wat jy kan bekostig.
8. Gebruik n "Bubble level" op jou teleskoop.
9. Leer die wind lees deur in die wind te skiet.
Soos alles hang dit af van hoeveel jy wil spandeer maar dit maak geen sin om n R5000 teleskoop op n R30 000 geweer te sit nie en as jy nie n budget het nie koop n S&B PMII (soos doomslayer aanbeveel) met die vergroting wat jy van hou (3-27 is awesome), enige kwaliteit staal basis, Spurh ringe (eenstuk), accuracy first bubble level. en n MILDOTMaster...
Ek gebruik n Vortex Viper PST MRAD (EBR-2C) FFP teleskoop in Seekings Precision ringe op n REm 700 300WM en kan verseker vir jou se dat dit werk, dit is n budget scope maar vergelyk met Nightforce se NXS kwaliteit teen die helfte van die prys. en dis in FFP (Nightforce het net die F1 3-15 NXS, ACTAR en BEAST met daardie keuse) Moenie my verkeerd verstaan nie, Nightforce is ongelooflike teleskope en die BEAST is iets uit n ander wereld. As ek eendag bietjie wil opgradeer sal dit egter n Vortex GenII Razor 4.7-27 wees...

Gegewe die kaliber sal sy maks effektiewe skietafstand omtrent (raak subsonies) 1200m wees. Kom ons neem die volgende tipiese ballistiese tabel as voorbeeld:
123 6.5x47 Lapua @ 2930
Zero 100yd 5000' Density Altitude
RANGE ELEV- moa mil | WIND(10) moa mil RANGE
100 0" 0.00 0.0mil | 0" 0.50 0.1mil 100
200 2" 1.25 0.3mil | 2" 1.00 0.3mil 200
300 10" 3.25 0.9mil | 4" 1.50 0.4mil 300
400 23" 5.50 1.6mil | 8" 2.00 0.6mil 400
500 42" 8.00 2.3mil | 13" 2.50 0.7mil 500
600 68" 10.75 3.2mil | 19" 3.00 0.9mil 600
700 102" 14.00 4.0mil | 27" 3.75 1.1mil 700
800 145" 17.25 5.0mil | 36" 4.25 1.2mil 800
900 197" 21.00 6.1mil | 47" 5.00 1.4mil 900
1000 260" 24.75 7.2mil | 59" 5.75 1.6mil 1000
1. Dan het jy 25MOA / 7.2mil nodig vir elevasie met n 100yd zero op 1000yd. Jy benodig n teleskoop met ten minste 50 MOA elevasie verstelling as jy n "zero slope" basis gaan gebruik. Kies verseker n 30mm of groter main tube.
2. Wat jy verkies MOA of Mil maak nie regtig saak nie en is n persoonlike keuse. Ek sal egter mil kies.
3. Soos genoem is die belangrikste dat die reticule en turret verstellings in dieselfde eenheid moet wees.
4. Kies n kruisdraad wat vir jou gaan werk - hou jy bv van die "besige" kersfeesboom tipes met wind en elevasie afmikpunte of soek jy n "skoon" tipe soos n Gen 2 Mildot. Maak net seker dat as jy die reticle wil gebruik vir afstand bepaal dat hy hom daartoe verleen.
5. As jy die regte kruisdraad kies gaan jy geen fout maak om n FFP teleskoop te kies nie. DIt maak alles net soveel makliker (lees vinniger)
6. Kies die beste basisse wat jy kan bekostig - verkieslik n eenstuk picatinny tipe en as nodig 20MOA sloped.
7. Kies die beste ringe wat jy kan bekostig.
8. Gebruik n "Bubble level" op jou teleskoop.
9. Leer die wind lees deur in die wind te skiet.
Soos alles hang dit af van hoeveel jy wil spandeer maar dit maak geen sin om n R5000 teleskoop op n R30 000 geweer te sit nie en as jy nie n budget het nie koop n S&B PMII (soos doomslayer aanbeveel) met die vergroting wat jy van hou (3-27 is awesome), enige kwaliteit staal basis, Spurh ringe (eenstuk), accuracy first bubble level. en n MILDOTMaster...

Re: Teleskoop spesifikasie voorkeuse???
Hier is 'n baie oulike samevatting oor MOA vs MILS: http://precisionrifleblog.com/2013/07/2 ... omparison/
Die skrywer het ook die opinie dat dit makliker is om MOA te gebruik as jy gewoond is aan yards en duime en MILS as jy gewoond is aan meters en centimeters, so hy weet ook dan maar nie te veel nie....

Aim small, miss small
