Spotters Calling Hits/Misses with MOA or MIL

For those of you that use spotters to call shots, I would really like your input on this.

I have always been a lone shooter and and a MIL based fan, thinking that the MIL reticle/turret setup with 1/2 MIL hash marks and .1 adjustments is about the ideal combination for a long range rig. I just like everything it offers, i.e., uncluttered reticle, turret adjustment coarseness, and pretty easy math.

I think if a guy is spotting his own shots or if his spotter has a scope or spotting scope with the same MIL reticle then the MIL system is ideal.

However, I watched Shawn Carlock's videos this week and he brought up a point that got me thinking about the potential benefits of MOA if you have a spotter that doesn't have a matching reticle in his scope or doesn't have a reticle at all to use through the spotting scope. In this case it seems much easier and faster to estimate the miss in inches and quickly calculate the MOA adjustment needed without any ranging reticle. So for a 1200 yard target 1 MOA is approx 12 inches so if a guy misses by 12 inches he needs a 1 MOA correct, 18 inches is a 1.5 MOA correct, etc.

If a MIL reticle or turret was being used there would be considerably more work involved to estimate the miss in inches then calculate what the MIL adjustment would need to be. For speed of the followup shot isn't the MOA system quite a bit better in this example?

I guess the reason I am thinking about this is I have not shot with a spotter before but will be soon as I have a son that is going to be shooting and hunting with me and a newer shooting buddy that wants me to teach him long range shooting and I am just trying to figure out what is going to be best in this example.

Input appreciated.

Re: Spotters Calling Hits/Misses with MOA or MIL

The principles are the same.

So, it comes down to personal preference based on your experience and the equipment you have on hand.

That said, most of us in the US are familiar/comfortable with inches although it doesn't hurt to learn the MIL system in order to be well rounded.

Re: Spotters Calling Hits/Misses with MOA or MIL

I've used both, and I found the MOA system to be easier for us to do the math quickly and relate to things in inches as well as moa if desired.

I think as time goes by, and more companies make moa reticles, people will begin to see just how easy and quick it is. Especially those of us in the US who think of things in inches and inches per hundred yards. (not exactly true moa, but close enough for most purposes, most of the time.)

My hunting partner and I were doing alot of shooting/spotting from 700 to 950 yds this past October, and a moa reticle isn't very cluttered at all at those distances.

I favor mil and my now 16 yr. old son has a few seasons with me. I have tmr reticule and he has one of my older mildot. I have a leupold spotter and I can have either tmr or mildot installed,and will soon.We spot for each other when we can

Re: Spotters Calling Hits/Misses with MOA or MIL

Learn and teach it all. It's always nice to know the angular measurements anyway, especially when communicating with others.

We were out trying to zero a buddies gun on a tgt. last week. He had a leupold 6.5-20x VX-III on top of his rig with tgt. turrets and plex reticle. From using that optic in the past i knew what the plex post tips subtended at 20x (1.4 MOA). When my buddies kid shot he was trying to figure out how many 1/4 MOA clicks to adjust left to achieve his 200-yd. zero. I told him to just measure it in the reticle. He said 2x crosshair to plex post tip. I said that would be 2.8 MOA. So he just adjusted his turret 2.75, and he hit the tgt. he was shooting at (a rock). I use my reticles frequently as measuring devices.

For what its worth, i eliminate math troubles when callings shots in mills related to distance by using meters as my unit for distance. crossing metric and imperial measuring systems is where the problem always starts.

As I stated earlier, I've used both. I learned mil before I learned moa.

I truely believe moa or IPHY is a better system, especially when talking about small amounts. We judge a miss or a wind drift or even some holdovers in inches naturally (at least most of us do). It just comes natural to refer to things in inches and therefore converting to shooters minute is easier................Even target size is referred to in inches (example: the X ring is 10" wide, that deer is 20" from back to belly, wind's gonna push us 5" left, gotta hold about 3" high at 300, ect,ect.) Who calls a miss by 1/3 mil unless they are trained to and have a mil reticle??? Besides, 1/3 mil is a pretty substantial miss IMO........it's nearly 10" at 800 yds.

Now if we're trained to think in cm and meters and mils and measure target size in yards.........that's another story.........Or, if the spotter also has a mil reticle they're looking through, then it doesn't make any difference. He calls a 1/2 mil miss to the left and the shooter then dials or holds a 1/2 mil right. Same scenario when they both have moa reticles.

Problem comes when they have different reticles or the spotter has no reticle.
Problems also come when the scope adjustments don't have the same units as the reticle. Imagine your spotter calling out a 1/3 mil correction and you the shooter having 1/4 min clicks (which I believe was kinda the original point of this post)........I can't convert 1/3 mil to 1.15 moa in my head in a couple seconds during the heat of the moment........how many can?? Same goes for calling a miss in minutes and the shooter having 1/10 mil clicks...............they need to be the same for lack of confusion and efficiency/speed.

1mil=3.44 moa, 1moa= .29mils..................these aren't easy numbers to juggle around in a hurry in my head. But, a 10" miss at 800 yds easily and quickly converts to 1 1/4 minute in my head. (not exactly, but very very close)

Sorry to be so long winded. It's obvious to me, but I seem to have trouble making it obvious to others. Hopefully that kinda answers your original question.?
