• Wind direction: 3 o'clock
• Wind speed: 10 MPH
• Altitude 1785 feet, Standard Atmospheric Model
• Temperature: 57 F

Bullet data

Country	Namne	Caliber	Weight	Speed at muzzle	BC
U.S.A.	.30-06	.308	150 gr.	2700 fps	0.335
U.K.	.303R British	.311	174 gr.	2440 fps	0.369
U.S.S.R.	7.62 x 54R	.311	148 gr.	2738 fps	0.36
Germany	7.92 x 57	.323	154 gr.	2880 fps	0.29

Note: all the data was obtained from the manufacturer of the bullets I used. With one exception. The BC values are from The History Of Sniping And Sharpshooting by John Plaster.
