Did you attempt to just go from a 100 yard zero to 1000 with no stops inbetween? Again I'll say it- on a range there is no huge surprize as we workup with intermediate distances.
That you had a 2 moa higher value with one scope vs another is interesting but if you use part of your geek-foo to RECORD that value where is the problem?
I have shot with many an engineer, computer nerd, doctor and I hate to admit it, a lawyer or two.
It is fun to keep track of them as they advance through the geek stages with meplat trimming, flash hole trimming, gadgets they bolt on, and such.
I do my best to look interested as they go on and on...and on about a new 'app' they use to compute firing solutions- as well as the tweeking they do to get the computer to get closer to real world, shot data.
I'm sure you are well known as a maven.
I just found the attempt to justify a .XXX valuer added to one inch interesting.
FYI I have owned 4 leupolds, NONE tracked true MOA. That included an old MK IV.</div></div>
notquiteright,
For my convenience, in preparation for 1000 yard tournament shooting, I zero and practice at 100 yards, and then come up, while at 100 yards, the number of inches my ballistics chart suggests will be necessary for the bullet path and line of sight to intersect at 1000 yards. I cannot depend on click count initially,whether perceived as having true or simple value, to get the come up needed since, with my iron sight radius, the clicks do not have an exact 1/4 minute value, but something a little courser, between 1/4 and 1/3. With this hunt and peck adjustment procedure my knowledge regarding the distinction between true and simple MOA is not exercised. However...
Since understanding the adjustment necessary to counter for everything that effects the bullet: gravity, drag, wind, and temperature is important, learning as much as there is to know about MOA, BDC, BSZ, and sight adjustment in general is not moot.
Knowing the difference between what has become known as true MOA and simple MOA is important too since not having an understanding could produce shooter error when adjusting from one distance to another.
Another good reason to know all about MOA is that some sight manufacturer's lie about click value, or, as when using user attached iron sights, the click value produced by a user selected sight radius may not be what is suggested it will be by the sight's maker. This makes any misunderstanding a source of potential error.
BTW, at least one manufacturer today of match conditioned commercial equivalents of the M16A2, fits those rifles with a rear sight which is advertised as having a 1/4 minute value when it actually has a 1/3 minute value. A new shooter who accepts that the sight has a 1/4 minute value will eventually become somewhat perplexed, as well as have success stymied.
No doubt, there are shooters who contemplate equipment as their salvation to good shooting, rather than marksmanship knowledge. Those interested in knowing how their sights work are clearly pursuing marksmanship knowledge. For these folks, knowing the distinction between true and simple MOA is useful for for a multitude of reasons.
