My Google fu is letting me down
If you have a 10x max spf scope with an MOA reticle will the subtensions measure in MILs at some lessor power, if so what?
Thanks

Or more correctly 2.9086678301 but it's not exactly precision we're talking about here is it, what's a few decimalsQuote:

Obviously you'd measure it with the scope in question to get it as accurate as possible . . .
Had the same scope found it dialled very well under the cap and hash’s were bang on I think 1x .250moa click is 0.07 mil vs 1 mil click being 0.10 mill so you could probably work it out that way as well for full zoom with a sticker saying what each hash is in mil “check my math though running off a distant memory Of a passing conversation”
Again my decimals may be in the wrong place could be 0.70
About 0.073 mil but again, who's counting
OK, so what's the math in your calc for the 2.9 anwer please, I know I should know this but my brain ain't working tonight!
10x / 3.438
1 mil is 3.438 MOA
I'm scratching my head, somewhere I have a conversion table that gives the crossover for a MOA scope to a MIL and vice versa. Can't put my fingers on it right at the moment but it won't be too hard to make it up in a spreadsheet. With the appropriate formula entered in it would do it for you and then you can fudge it (round up or down) for readability if you wanted.
I think the one issue I noted with the conversion table is some scopes have a different thread pitch on the adjustment screws which means a different adjustment amount per full turn of dial - not really a major. I'll have a look for it later.
As you decrease mag the relative size of your reticle marks increases, with sfpQuote:

So at 2.9etc x, 1 "moa" actually is 1 mil

Yes. It's rarely practical in my view, I prefer not to have to think about it.
I've tried it in the past and it is impractical. However with a 3-10 where you simply turn it to low power (albeit with about 1/10 error if the scope magnifications are true) then maybe it usuable for @tikka 's method . . . Stacked tolerances might sink it and I'm to tired to analyze it just now. Thanks Gimp.
You could use 5.8ish. 1 "moa" hash should be 0.5MIL. Calibrate it by adjusting mag on the range til the reticle hashes match a measure downrange. Make a witness mark so you can hunt with it at that exact magnification
To be fair though I prefer my method which I use very effectively and quickly - the DIY BDC turret

Haha, nice. I'm not that keen on non locking exposed turrets, another thing to move accidentally (or not reset) and confuse the elderly!
Where SFP with a BDC reticle can come in handy is with different loads, I have it at 100m zero for full loads and for subs at 50m zero it's the 400yd line at 6x. At lot easier than having to dial.
Any system requires intentional familiarization for proficiency
