Go to the link below. Down at the bottom, change column 1 or column to adjustments to mils.

Just choose Sierra .308 cal 175 HPBT out of the Library drop table at the top of the page.

Each of the input boxes on that page has a link beside it which looks like a question mark. Click on that to see what the program expects.

This is about the minimum data set you must enter for the program to work:

Ballistic coefficient
Bullet weight
Caliber

Muzzle velocity

Sight height

Zero range

Temperature

Pressure - this is the tricky one. See the section on entering atmospheric parameters in this link:

http://www.arcanamavens.com/LBSFiles/Shooting/Downloads/Baro/

Humidity - however, if you checked the box which says, "Standard Atmosphere at Altitude", that box will not matter. That's one of the reasons why it's better to have your own pressure reading, because then you can also enter the humidity and it will calculate that.

Down at the bottom, check the boxes which say:

Elevation correction for zero range
Target relative drops

For M118LR
Use 175 SMK [LITZ] in JBM for the bullet
Use 2600 fps as the MV
