when there's a shot opportunity, even when shooting at long distance rocks, my feeble mind will screw up every time when there is the slightest "thinking" regarding Mil reticle and MOA turrets.
If I had a Mil reticle in the spotting scope the rifle scope would be in Mils also. Much more straight forward when calling shots. (no mental math)
Mil units are larger than MOA. The human eye, at least mine, are very good at discerning partial units with either a Mil or MOA reticle. However a standard Mil Dot reticle is difficult to discern in the 0.7 to 0.8 range. Too much thought at a critical time is my problem. Mil dots are usually 0.20 Mils in diameter which makes the edge of dot 0.10 Mils from the whole unit. A half mil steadia makes things a lot better.
Besides all of thata IIRC Mils are a military thing for ranging humans. Hell, I hardly ever shoot humans.
I'm with Broz on this one. MOA are simply more straight forward and more effective such as fine tuning drops using clay birds at well beyond 500 yards.
I just invested 160 bucks, after decades of waffling, changing a TMR reticle to a TS-29 to eleminated one step in the thought process of making the shot. Plus I'm now good to a bit beyond 1500 yards without touching the turret. We'll see how I like that....
