Using Mil Dots

[arubino19]

If my scope is sighted in at 20 yards. And my shot is about 40 yards away which mil dot is generally the correct one to use? Does anyone have a cool diagram showing how to use mil dots at different yardages?

Depends on a lot of things, including scope height, what magnification your on, your fps, bc, and more. Hawke Optics has Chairgun, a free downloadable program that is awesome!

I suppose so because I just nailed a shot at 40 yards or so using the first mil dot low from the center. But according to the YouTube videos I've seen that shouldn't have been the correct dot lol.

This is just off the top of my head, but if your sighted in at 20 your second zero is probably about 35 so 40 is just a little down. I use MPBR (chairgun figures) and I think my zeros are 18yds and 33yds. I think 40 drops off pretty rapidly for me though. Oh, &^^&, I'll just crank it up. Zeros at 15yd and 37yd. Down about a quarter inch at 40yds. 2 inches down at 50. Wow, I'm sooting really flat.

So what I have to remember, or write down, is zero at 15, half up at 25 and zero again at 37 (40). Use a different ammo and it's different. Also I should verify this by shooting at 25 and 40, but my backyard is only 10.

Andrew,  just download Chairgun Pro.   It's free.
You'll be happy you did.  It'll answer your questions, and even has a illustration thru a mildot scope at whatever target you choose.   It's a good tool!

Easiest and most fun is to go out and set up some targets, choose your pellet and use same pellets, check zero. Then learn which holdover/under works with magnification chosen. Even if you make a range/magnification card with Chairgun, it's foolish not to verify.

Yes Sam....it's foolish not to verify.  We give the folks credit, that they use Chairgun as a tool.  It is a very good tool.

   There is no correct way to use a Mil dot reticle as far as zeroing goes. Most guys like to sight in so they can use the center of the crosshairs for the as much of the trajectory as possible. Any distance closer and further away than that PBR you will have to hold over for. Like was mentioned above, it entirely depends on you gun as to what kind of trajectory you are working with. The goal is to figure out where the pellet is going to be at each range so you can accurately compensate using the reticle.

I use chairgun, but you have to keep in mind that unless your scope is HAWKE the program isn't made for the exact scope you have, and if your scope doesn't go to 10 power, some OTHER calculations will be off too, i.e. the hight of a given target at 100yds, 50 yds (twice as high) etc.
Well, there is a selection of generic reticles in the chairgun program, so you MIGHT luck out!
I like to shoot alot, so I enjoy the job of verification. I set up targets at 10, 25, 40, 50, 55 yards and jot down on paper which mildot gets me the hits I want.

It works fine with Mildots.  They're standard Milspec.

Chairgun is very accurate if you enter all your data correctly (does not have to be Hawke). The only change I see is when you do not hold the same way and wind (but, wind can also be calculated).

This is the best way.

Get out there and shoot! That's the fun part.

It wouldn't hurt to make a data book for each gun you have. That way, you can keep an accurate history of your shooting sessions. You will learn more about your gun and shooting ability than you ever could just plinking around.

Chairgun is amazing software but imo, you still need to verify with your particular rifle.

No posts other than that one made any implications or reference to using the Chairgun Pro program as a substitute for shooting.  It affords the user some insights to variables, that they would like to investigate, without having to make extra purchases or physical changes to his/her setup.  Again, we give credit to our GTA members, that they are using it as a tool...It's a good tool.  Why own one and invest the time...if it's not to be shot?

+1 Chairgun is the bomb.

I assume you are referring to my post.

It was never my intention to imply that one might use a substitute. The original poster's question, in it's purest form, was how to use the mil dot system. The member's second post stated that their results did not match other data found online.

Given this information alone, does it seem too far stretched to suggest "your results may vary"? That was my point.

Go to youtube and do a search for Teds Holdover.
He has two different videos dealing with mil-dots, one shows him making targets that aid
in judging size at certain yardages and the other shows how to read the mil-dots and dial in for that range.
He makes awesome videos and has made some really impossible looking long range shots.
This will help you with your mil-dot question.

I found them.

Chairgun is good software and somewhat useful and actually may be of some help. I learned how to shoot without computers, actually learned how before I went to Marksmanship training which was taught by a real Instructor only using visual aids. So all you need is trigger time and chairgun doesn't provide any. Practice, practice and more practice is the only way to learn?

An I still don't need software, trigger time before cyber time will make an accurate shooting marksman. But if you are interested in some cyber reticle range finding practice with  FFP mil-mil is state of art or you can test your math skills with SFP moa-mil or moa-moa scopes to learn the fundamentals of reticle range finding before launching a projectile/pellet down range towards a bullseye. Is the shooter ready, no?

http://www.shooterready.com/lrsdemo.html This is the intended use for Mil-dots! You may want to attend the class room before jumping into the simulation. Use your mil-dots however you choose and have fun. 

Nowhere have I ever made the statement that chairgun replaces actual real world trigger time and KYmike is making a false statement that I did.  Read this post  for yourself.

Sam...
None of us "NEED" it.  No one but you imply that folks are using it as a substitute for practice time.
It's a fine program, that gives us a tool to work with, BEFORE we get to the range.  Understand that we all don't have 50, or even 30 yards at our ready disposal.  For those folks, it's very useful.   Don't worry Sam, they are shooters that are trying the best they can, to be their best

I am a veteran Sam, as are many of us.  We are well versed.  We don't wear it on our shoulders.  We are also shooters, that enjoy...and INVITE...any new innovations that helps to bolster interest in this hobby.  And technology is something that shouldn't be met with disdain or condescension.  Mike

it is universally known the chairgun is such a benefit to all airgunners.  it is also known that trigger time is invaluable and cannot be duplicated.  but with both and applying them, there is no limit to what you can do and/or achieve.
