I lost my book awhile back. Not only did it have all my maintenance stuff, but it had a scope dope in MIL Dot for 55, 62 and 77. standard numbers. If you have the info handy can you post it here. sierra, HPs, standard vel from 16", sea level, normal baro...

If you have the data on the rounds I could just use that in my calc and build the cards again. I know I am being lazy but I can't even locate the data to plug in the numbers.

I dont own a iPod, iPhone or droid so the app will not work for me. I like the hard data in a book and I can play with the numbers in my head at the firing line.

anything you got will save me some time.Thank you.

OH thank God...I found the program I was looking for. dam its broken...looking again

Elevation Correction
6 foot target measures 2.50 MIL Dots in scope is 800 yards away.
Turn elevation knob 70 clicks or to the “7” setting.
Wind Correction Starting at 70 clicks…
There is a 8MPH wind toward target, 8mph X.2 = add 1.6 clicks to a total of 71.6 elevation
There is a 8MPH head wind from target, subtract 1.6 clicks to 68.4 elevation
There is a 8MPH left 90degree cross wind, no added elevation, add 8x5.3=42 clicks left POI
There is a 8MPH left 45degree cross wind, toward target, add the offset to the MPH=4MPH X 0.1 clicks for a total of 74 or a setting of 7.4 on the elevation dial and the MPH X the drift offset = 4MPH X 2.65 = 10.6 or 11 clicks left POI or a setting of 1.1 left drift.
Elevation dial = 7.2 (72 clicks) Windage dial = 1.1 Left (11 clicks left)


found this is 308....I need this for 5.56, 55gr, 62gr, 77gr...grrr:mad::mad::mad:

fixing this data to be displayed as i found it...hang on. I think the 308 guys will like it.
