Re: Mildot measurements
You answered your own question. Just do the math.
You already know that 1mil subtends to 7.2" at 200 yards so...
7.2 / 200 = 0.036
Just multiply your desired yardage by 0.036
450 * 0.036 = 16.2"
550 * 0.036 = 19.8"
The actual formula is:
Height of target (yards) X 1,000 = Range (yards)
/Height of target (mils)

Re: Mildot measurements
So if my drop is 32 3/4" at 450yrds.Impact should be very close on second dot?I know there is no substitute for real dope.Just trying to figure some holdovers on my build without wasting ammo.

Re: Mildot measurements
That will get you close, but you really need to plug your data into a ballistics calculator.
JBM Ballistics is online and free. You can set up columns that will tell you how many mils to dial and/or hold.

Lots of other options out there if you have a smart phone. Look at iStrelok. It has a decent ballistics engine, but the hold-over outputs for different reticles is excellent.
