welshwarrior Posted October 23, 2015 Report Share Posted October 23, 2015 Ok looking to get back into longer range shooting again. When I last did it I always used MOA but now looking at MRAD I can see a slight advantage but not used a scope in anger with it. What's people's views preference and why.

steve_b_wales Posted October 23, 2015 Report Share Posted October 23, 2015 In a nutshell, MRAD gives you more precision for zeroing than MOA. But there's more to it than that of course. 49p a word and I'll tell you! Quote Link to comment Share on other sites More sharing options...
welshwarrior Posted October 23, 2015 Author Report Share Posted October 23, 2015 Sorry how does an angle give me more percission accuracy zeroing than another angle? Quote Link to comment Share on other sites More sharing options...
Kalahari Posted October 23, 2015 Report Share Posted October 23, 2015 1 minute is 1" at 100ydx, Imrad is 1cm at 100metres, but most minute scopes do 4 clicks to the minute which is quite a bit smaller step than i mrad. Probably need to start looking at exact models to do a comparison. David. Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted October 23, 2015 Report Share Posted October 23, 2015 That extra penny per word is really valuable as this is totally wrong I just Googled it and that's what it said, more or less. Quote Link to comment Share on other sites More sharing options...
hambone Posted October 23, 2015 Report Share Posted October 23, 2015 (edited) Got to ask the question, what is MRAD and more importantly does it offer significant advantages over MOA to the average shooting man. Hope a brief explanation is FREE as 50p a word is a tad excessive. Though maybe better value than wrong information @ 49p Edited October 23, 2015 by hambone Quote Link to comment Share on other sites More sharing options...

Savhmr Posted October 23, 2015 Report Share Posted October 23, 2015 It doesn't really matter which you use providing that your ret and turret adjustments are the same or simply use a duplex or fine ret with enough adjustment for dialling in ranges. 1MRad = 3.438MOA Scopes for target in Rads tend to be 1/10th Mrad per click. 1MOA = the angular measurement given by 1/60th of a degree which subtends approx 1.047 inches at 100yds (which is why most equate MOA with 1 inch at 100yds as close enough) or 10.47 inches at 1000yds MilliRadians is based on the Metric or SI angular system. A radian is the angle at the centre of a circle described by an arc of corresponding length on the circumference, so there are 2 Pi Radians in 360 degrees which equates to approx 6283 Milliradians of angle At 100m, 1 Milliradian = 10cm so 1/10 scope clicks = 1cm per 100m as opposed to 1/4 inch at 100yds for the MOA system. Not hugely different and both systems are perfectly adequate for 1000yd shooting providing you dont mix your units up! The common way this is done is to have a scope with MilliRad reticles but using moa adjustments which can be a pain when doing the maths. Better if using the rets, to have them matching whatever system you use. For target, I use both types, a Milliradian ret with 1/10 Mrad adjustment and another scope using MOA and fine ret. The use of MRads was adopted by some (if not most) armed forces because combined with an MRad ret, it also allows for (approximate) range finding and rapid estimations for holdover and windage when using a FFP scope on any magnification. I dont really find much advantage of one over the other but I'm not really a serious target shooter. Some that are may be better placed to offer a view on whether one has any real advantage over the other. Quote Link to comment Share on other sites More sharing options...

LeadWasp Posted October 24, 2015 Report Share Posted October 24, 2015 (edited) CTRL C + CTRL V = Free Now tell him about the way the manufacturers manage to destroy all the logical simplicity of this with 12.5 MOA per turret rotation and pointless 1/8 MOA clicks. Why 5mm clicks in theory are superb but usually executed badly so becoming pointless. The Mrad system IS far more logical because of the base ten calculations BUT Not when an accountant gets involved. Why the Mildot reticle has for years cohabited with MOA adjustements. Its all painfully complicated. The biggest surprise is the new Swarovski X5i has been done in MOA after years of metric adjustments 'because it is more accurate' yet they make the STR spotter in both? Ahem as I might have suggested in a prior conversation you should write that book and get paid many times over. I'll cut you a Hardox gong for each copy to be used either as a book mark at bedtime or a paperweight out in the field Daf if we catch you bambiing over 150yds you know it means the naughty step!

Staffs have all ready told me I need to surrender all my Pop guns while my case is heard for having my under pants the wrong way round. My solicitor recons I should get off it due to a Technicality as I thought the zip should have been at the front. I am expecting early next year. mega P d off but hey ho my fault i cant really have a go at anyone else I am looking at getting an Air rifle though.. I just hope I dont get forgotten about just because I cant get this year, besides that the days are getting shorter. Quote Link to comment Share on other sites More sharing options...
Savhmr Posted October 24, 2015 Report Share Posted October 24, 2015 (edited) scope buying is a mine field what are the pros / cons of first / second focal plane too? SFP means that the ret is located in the second focal plane and that the size of the ret therefore stays constant irrespective of magnification. They also have a slight parallax shift with changes to magnification so on some, you may find that zeroing at one mag gives a slightly different POI on other magnifications. The main drawback is in conjunction with MilliRad rets (and other ballistic rets) where they will only be accurate for the scale at one specific magnification. For general purpose Duplex rets and decent optics, SFP is fine. FFP means that the reticle is in the First Focal Plane and therefore zooms with magnifications. Ballistic type rets, including Millirad rets are accurate at all magnifications and they do not suffer with parallax shifts with magnification. They are by far the better system if your primary use is target. For hunting the centre ret can appear very feint at lower mags. Duplex or other simple FFP scopes are accurate for POI at zero for all magnifications. Edited October 24, 2015 by Savhmr Quote Link to comment Share on other sites More sharing options...

welshwarrior Posted October 25, 2015 Author Report Share Posted October 25, 2015 For me FFP is the only option for this sort of use as the reticle stays calibrated through out the magnification range allow the stadia to used for range finding and rapid adjustments when needed and secondly it's what I'm used to. To me MRAD or Mils radian has the advantage of being a base 10 system and one I've used a fair mainly in binoculars but also in scopes. MOA tends to be a more commonly spoken language in target shooting but I doubt I'll get back into that so it's a lesser advantage to my intended use as I doubt we'll all be discussing the adjustments I'm becoming more and more convinced it does not matter with you use as long as you learn to use it and stick with BUT turrets and reticle must be in the same system. To guys reading this for info as others are said their been a few old myths dragged up that are rubbish so read into what your reading.

Check your maths MOA at 100 yards is 1.047" and MRAD at 100m is 10cm SMOA is 1" at 100yards an example of needing to know exactly what system you have.
