So I am Zero'd in with my AICS Rem700 .308 with 168grn TAP Police Ammo, my scope manual says at 600 yards the drop is 92 inches and 1mil equals 21.6 inches, so 4 mils equals 86.4 inches...therefore I need to come up 8 clicks as each click equals .75 inches...

The part I dont get is why 8 clicks when each click is .75 inches and I am 4 mils off which equals 76.4 inches...? This confused me...

thank you in advance...

also if it is 4 mils off at 600, then I can just aim using my 4th mil dot correct and achieve the same results...?

You are sort of right, but you are on the wrong track on how to do this...

Why even bother to discuss inches since you are using mils and why do all that long hand math.

if you want to start yourself on the right foot,

First when you zero your rifle invest in a chronograph, even a cheaper one, and get an actual muzzle velocity. Then you can have actual dope for your rifle and not a generic set of numbers the scope manual gave you.

If this is not an option, and even if it is, I suggest rolling over to JBM Ballistics on the internet and putting your data in there changing the output to mils. There is a link to JBM on the front page of Sniper's Hide.

You can input your data, if you have actual muzzle velocity that is the best, but if not you can use what the manufacturer says as a starting point. 2700fps is probably a good starting point. Then simply tell JBM at the bottom to output your data in mils, you can then print the card.

It will be slightly off and as you develop actual dope you can fine turn your mil data.

Converting from inches is the long way around things. If you have your drop in MOA you can easily divide it by 3.43 and get your actual MOA drop in MILS. As an example 16 MOA (which is pretty close for 600yards) is 4.6 Mils so you are saying 4.8 which means you'll be in the ballpark.

But you are close,

Lowlight thank you for the link and your comments...!!!

I went to JBM website and inputted the info and here is what was returned:

My question is at 500 yards it shows off by -3.3mil, does this mean 3 mil clicks of elevation...? (sorry if the question sounds silly)...

thanks...
 
Re: question - .mil scope and clicks @600y 8 clicks?

If you have an actual drop number, then you can adjust the Muzzle Velocity up or down to match your dope. You might want to compare it too 2650fps.

But 3.3 Mils is about right for a 308 to 500 yards.

Stop thinking in CLICKS, think in whole numbers as in 3.3 Mils. 3.3 Mils is actually 33 clicks, (.1 Mils per click ) but you have to look at the whole number, clicks is a bad way to look at things and speak to someone because not everyone uses the same click value, especially in MOA scopes.

Thanks again, I will forget the word CLICKS : ), and it should have been obvious to me that 3.3 = 33 up...thank you again...now I just need to hit the range and test it out...!
