Posting a link to another forum, but this is a great resource - why MOA is important. (Stop it with the inches!!!)
Minute of Angle Definition and Why Understanding MOA is Important
I was explaining MOA to someone today and searching for a diagram and stumbled across the above link. Fantastically written and great pics. Just read the first post, don't worry about the muppets who replied.
Enjoy.
He says you need to be precise and yet states that 1moa at 100yards is 1inch
Guess im one of the muppets :D
60 seconds to the minute, 60 minutes to the degree and 360 degrees to the circle I love my old compass and imperial micrometeras well . It's all just simple maths and straight ratios. More often than not now I use a mildot scope to estimate range as shown in the diagrams rather than fumbling round with binos, rangefinder, rifle again now where's the damn deer gone?
Hahaha shhhhhhhhhhhhhhhh I quite liked that bit too :DQuote:

Fractions fkn shit me and anyone who thinks "one thou" is a fine tolerance - its only .025 of a mill.
Did I mention I think inches are balls?
My metric 2c
Something's sound impressive in inches :D
I was brought up with imperial, it's right through my aircraft industry, I love it 😆
Just my tuppence worth 😉
Watch the NSSF videos on MOA and milradians.
Best way to do this IMHO is to start off by asking what length is a minute of angle at the distance I'm shooting at...
If you're shooting 600yds, a MOA is roughly 6 inches. If you need to move 12 inches that is 2 MOA, if you need to move 3 inches that is 0.5 MOA.
Some guys I've seen shooting would rather work in feet!:XD:
I use seconds of angle at work, wish I could shoot that accurately as well!
Good bit of reading cheers dougie. Just to check its sunk in correctly if you were shooting at 500yrd and the shot was 5inches off you would adjust it 1moa ?
I've got twelve inches but I don't use it as a rule.Quote:

I don't think inches is dead yet.
Inches will never die CraigCQuote:

Other than that I do use MOA sort of, ... the conversion is not quite that easy when the ranges round here are in metric so 25m, 50m, 200m etc. I suspect a lot of the confusion comes from the fact that the unit symbol for MOA is the same as for Inches.
Actually... ' can be minutes or feet, " can be seconds or inches.Quote:

The main reason women have such trouble with inches I think is that they are constantly told 4-6 inches is actually 9-12 inches :D
Ha ha ha ha and we all think they believe itQuote:

It's OK! They measured everything in imperial and drove everything in imperial. Just that tricky rocket science bit in the middle they had to admit defeat. Particularly when you when you think where they got most of the technology and brains from.Quote:

1 MOA at 100 yards ( 91 meters ) i believe is 1.047" so basically 1 inch for hunting purposes.
