Not to worry, you're on the right track.

Over the years, I've known alot of people (that consider themselves hunters or shooters) that don't know how to get what you came up with in your original question. You'd be amazed at the number of people I've seen on public ranges that can't even get their own scope sighted in, simply because they don't understand the basic "1/4 inch per click" and that it grows with distance.

Best of luck.

Re: MOA setup help

Someday we should post a sticky thread listing our determined scope adjustment values by model. If known, particular reticle subtensions could be stated also.
Could be pretty useful.

I've only tested MK4 scopes, because it's all I use for hunting, and so far all have actually adjusted true in MOA(1.047).
I've 'heard' that most other leupolds are IPHY, which is great if known and accurate.
And I've heard that NF scopes are actually neither at 1.09"..
Yet all are listed as MOA of adjustment..

Gnats... You're right, who needs to worry about 0.047" difference at 100 yards?
though the average size of a gnat is about 0.039".

Now,
1 MOA = 1.047" at 100 yards and 10.47" at 1000 yards
1 IPHY = 1.000" at 100 yards and 10.00 at 1000 yards

Up to now, we would still be thinking about the gnats deal... but know instead of
just making a comparison let's get a real world example.

Let's say your rifle scope is calibrated in inches, 4 clicks = 1" at 100 yards.
now from a ballistic table you know your turret needs to go up 23.2 MOA; take
the shot and the big awesome buck just walks away into the timber.

What happened? For each 4 clicks you lost 0.049", so... (0.049 X 23.2)=1.137"
which at 1000 yards would make a difference of 11.37" allowing you to
miss the buck.

You needed to come up 24.3 IPHY on your turret instead you came up 23.2 IPHY
thinking that a gnat makes no difference and you actually missed by 292 gnats!

Written in the spirit of helping with a funny twist but very respectfully!

Good posts!

Re: MOA setup help

Good advise............ Verify you adjustments are in fact moa and then forget 1/4" @ 100 x range......it does not add up except for initial zeroing at close range. I only mention it because the compounding problem of discrepancy x 23 had me pulling my hair out a while back.

CORRECTION

(0.047X23.2)= 1.090"
which at 1000 yards would make a difference of [B]10.90"
you actually missed by 279 gnats!

Re: MOA setup help

Personally, I love the fact you can use a gnat as a technical measurement. Well Done.

Re: MOA setup help

Ok i keep coming back to the info posted and i cant wrap my brain around it.if 1moa is 1.047 @100, thats 10.47@1000 correct? For quick math on the trigger if u round down to 1.0 moa@100,10.0@1000 correct? My math gives me a differance of .47"@1000, i only wish i could shoot 1/2"groups @1000.( these are texas gnats, .25", only missed be 2 ).
