Re: Which angular measurements MOAvMIL do you prefer?
This is a re-post, but some might find some useful tidbits in here:
It doesn't make a huge difference, it's mainly a matter of preference. If you have a safe full of USO or NF MOA/MOA already (or shoot with a bunch of buddies who do) it wouldn't make much sense to buy a Mil/Mil--unless that's all the particular model of scope you wanted to buy offered (such as S&B, etc). If it's a relatively fresh start, that's another story. I like Mil/Mil better for a few reasons, but keep in mind they're only my personal preference. They aren't that big a deal, but they're why I like using Mils:
1) Click value. I don't do BR or F-Class or any other paper-type competitions (where people actually like 1/8 MOA clicks) and don't hunt varmints too often anymore, so .1 Mil (~ 1/3 MOA) I find to be "just right" for size. A good compromise between precision and speed/simplicity. I had a 1/2 MOA click scope and did find it to be a bit coarse for my tastes but I've never felt that way with .1 Mil. Also in virtually every case, a Mil scope will have more travel per revolution of the knob which I really like.
2) Simple numbers. Two digits with a simple decimal for drops (until you really get WAY out there) just gives a nicer number to work with. Say at a certain range your drop chart says 6.9. Or it could say 23.75. Or 23 + 3 or 24 - 1, etc. 6.9 is easier to say, to write in a chart, to read from a chart, to find on the dial, to measure with a reticle…. I just find the simple numbers to the tenth easier to work with.
Say you range something and look up in your chart your 10 MPH wind correction for that range and it's .7 Mils, for example. You measure with your Kestral, observe foliage and mirage all the way to the target and you estimate your total average wind value to be 7 MPH. What's your hold? .49 (.5) Mils . How about 3 MPH? .21 (.2) Mils. How about 11 MPH? .77 (.8) Mils. How about 15 MPH? 1 Mil. See how that works? Now try the same for 2.5 MOA. If you're good at math, it can certainly be done, just not as quickly and easily (for me, anyway).
3) It's Universal. While there are several companies coming out with MOA reticles this year--which I do think is a good thing--for those who just can't change (for reasons real or perceived), scopes with Mil reticles outnumber those with MOA by likely hundreds to one. All the world's militaries. Even in civilian market scopes EVERYBODY makes a mildot reticle or some variation. But for many years NF and USO were the only game in town for MOA.
It's even worse for spotting scopes. I got a spotter with a really nice Mil reticle several years ago. I believe at the time nobody made a spotter with an MOA reticle. Nobody. Now there are a couple but from a numbers standpoint it's a drop in the bucket. Being able to spot somebody's shots with an actual spotting scope vs. your rifle scope and being able to call corrections in actual angular measurements instead of guessing feet, inches, etc, is really, really, nice.
That doesn't really matter if all your shooting is done alone. But if you go to competitions, informal shoots or anything where a bunch of random guys get together and plink at long range, the chances are much higher that people will be calling corrections in Mils either from a spotter or by using the scopes on their rifles. It's not a big thing, but it's there.
If you want finer clicks, MOA has the advantage. If you actually plan on ranging things with your reticle a lot, many do find MOA/inch easier to do in their heads. I use reticles to range very little. When hunting I have a cheat sheet taped to my stock so it doesn't matter anyway. For impromptu targets a mildot master or a phone app works well. And as I said, if all your buddies have NF's with R2, R1 reticles, or similar you might not want to be the odd man out.
Anyway, that should get your gears grinding.
