At what distance do you stop being a threat?

Slide rules and notes, naturally, but you can interpolate from tables. In @M118LR 's example 5 mildots = 6' @400 yards. The geometric ratio between mildots and distance is linear, so if the distance is multiplied by 5 then the mildots are divided by 5, giving you one mildot.

 

Interesting - I'd assumed it was a smartphone app...

 

This isn't a math quiz, but how many average Americans can figure out what the simple 5 foot 10 inch target is that 3M-TA3 provided on the AUTO RANGE FUNCTION of the ACSS reticle. PS: BZ 3M-TA3. Later we can get to the MSR Reticle on the Steiner's & S&W's. But if we jump the basics, we shall leave the herd. The object is to go slowly and spoon feed those that haven't spent a lifetime doing this. JMHO.

Now we have had a request for more info on the MILDOT MASTER, but I'm to slow so others have shared, Thank You.

 

Beautiful thing about a mil, it is a section of a circle, so as long as you use the same measurement for elevation and distance, it will work with yards, meters, cubits, etc. Take your pick, read the theory, get confused as h***, spit down wind and use it as it always works and I really don't care what the math is.

Thank you for the post and the picture, a long range shot around here is 100 yards, most hunting shots are 50 yards or less. A lot of food for thought in that picture and the little chart attached to it.

 

M118LR, to answer your windage question I'd need to look around more...how far does the wall extend, what kind of windbreak do the trees provide, etc...to make an educated call. Can't just go by what is in the immediate vicinity.

 

So as every shooter knows, elevation is the easiest part of the ballistic equation. Haven't heard much about what the wind conditions, (or terms related to them) from the 400 yard snapshot.

 

How much dust is being raised on the dirt road? And how do you determine wind speed and direction from dust? Mirage is dependent on using the same power scope every time, dust drift has known qualities. This isn't a test, only inspiring questions techsar. This entire scenario is to be played with nothing more technological than the scope on your rifle. (In the end, it's all you can be assured will be functional. JMHO.)

 

Keep going, guys, your getting closer!

 

Oh we haven't got to that little black book in the side pocket on my butt stock yet Ura-Ki. Perhaps it might hold information of real relevance .

 

Assuming a 7.62X51 @400 yards, what's the actual hold? what's the wind correction?
.300 win mag?
.338 L.M?

Note, all three have a very different correction factor!

 

In these wind conditions, dead on for my 400 yard Zero off the come up page, all the above. 2k for the .338 or 50 BMG we can discuss in if a 201 class is needed. JFYI 2k with 300 Win Mag & 7.62 NATO isn't worth conversing about. More than my opinion.
So is it okay if we get back to the original simple Simon objective for other folks?

 

So as silence prevails, are the folks in the snapshot a serious threat to those of us behind the scope?
But that wasn't the question asked at the onset, was it?
But what do you see in your glass?

Please allow a time frame for us Old Folks to nap.

 

Tango's weapons are not up and ready, and they are not alert and looking, so it's a yes and a no!
They are still with in their weapons range, and it they get alerted you better be ready to take the shots!

 

Drag me back from the dead will you!
J.C Never Sleeps. Not until GOD arrives on the scene.
Now that's a little on the Sailors Lexicon Side, so I'll give you my time off watch to digest it Ura-Ki. (Tee He, Tee He) LOL

So you want to give the kindergartners an explanation of what it means to depend on the man above? (usually it's just a SNIPER on a rooftop.) But they still hear a soldiers prayers to get "Home to the one's they love" Just My Experience. Nay say me at any time.................

 

I just grabbed some tin's of soda crackers and peanut butter along with my ration of ammunition and a National Match M-14 on my way out to the jungle. It's just me and only me against everything the Jungle can dish out. But all the high tech $H!T ain't stopped me yet, so come dig me out of the mangroves. Got allot of rice feed folks that are thumbing thier noses at you somewhere around here. LOL.

 

No worries with the big guy above, I got it covered at 120 knots and 500 feet AGL with the M-21, just have to figure the reverse angle lead, and let er rip tater chip! You ground pounders can keep that nasty chit!

 

Laughed so hard it ain't worthy of a LOL.
I'll share my crackers with Y'all if you care to come along....... But Y'all need to be able to shoot straight, swimming is a +. LOL
