Correct me if I'm wrong. Is 1/10 MRAD worth about .36 inches at 100 yards?
One radian is 100 yards of arc at 100 yards of distance. That's the foundational thing to remember.
That's why the military uses it. Radians "absorb" the trigonometry into the unit. It's better to have a bunch of crayon-eaters doing arithmetic than doing trigonometry.
If you want to use MRADs you might want to adopt the metric system for shooting. 1 Mil is 10cm at 100m. It's 20cm at 200m.
Here's a nice writeup on it: https://www.schmidtundbender.de/en/service/did-you-know/127-turrets/1521-moa-mrad-mil-cm.html#:~:text=MRAD or MIL&text=0.1 MRAD/MIL is 1,1 cm at 100 m.
The metric system is so simple.
But converting either of the unit systems for angular measure to ANY linear measure is just a waste of time...
MIL is all base 10Correct me if I'm wrong. Is 1/10 MRAD worth about .36 inches at 100 yards?
Knowing how to do math without a calculator isn't a waste of time IMHO.But converting either of the unit systems for angular measure to ANY linear measure is just a waste of time...
True, but it delays the learning curve if learning MRAD. That said, yes, it can help.Sometimes it can help people understand. Or help them sight in an optic. Or range find with a reticle on a target of known size.
Well of course not, but (IMHO), that's not what he is saying. He's simply saying use either system, but don't waste time converting etc, just use the system. Most of us know what inches look like, we've used them all of our life. We have to learn what Mils look like downrange. When I stopped trying to convert to inches to "help" me understand the space, Mils got easier/faster to learn.MIL is all base 10
100 yards is 3600 inches
1 MIL would be 3600/1000=3.6
.1 Mil would be 3.6/10=.36

never have to worry about doing any math at all.
Right I would to but those countries us metric.... and the debate is about conversion, and I don't see usa prs shooters making wind calls in kph.Both actually, In Canada or UK I would expect KPH
The more knowledgeable guys can correct me if I'm wrong , but I would expect that if they did, they wouldn't convert from KPH to MPH before deciding on the hold or visualizing the hold a other shooters talking about.Right I would to but those countries us metric.... and the debate is about conversion, and I don't see usa prs shooters making wind calls in kph.
I would not make a statement about the group as some dial, some hold over.... the only certainty is the guy that does it differently will chime in... do what works for you....The more knowledgeable guys can correct me if I'm wrong , but I would expect that if they did, they wouldn't convert from KPH to MPH before deciding on the hold or visualizing the hold a other shooters talking about.
The way i see it....Wind calls could be in KPH, vertical could be in Mils, horizontal could be in MOA.
As long as you're working within those systems and not trying to use one for the other, you really don't have to do any math.
