Excerpt from 12-Inch Range Table: 2, 700 F. S. Initial Velocity to 22, 000 Yards, Long Pointed Projectile Coefficient of Form .61, Weight of Projectile, 870 Pounds; Siacci's Method; Corrected for Altitude, Ingall's Ballistic Tables
This table is calculated for a temperature of the atmosphere of 59° F., and a barometric pressure of inches, the air being assumed to be half saturated. The powder is assumed to give normal velocity when at 90° F.
Ingalls's ballistic tables have been used for computing columns 2, 3, 4, 5, 6, 8, 10, 11, 12 as well as for computing the altitude factor in the ballistic coefficient.
Alger's formulas were used for computing columns 7, 13, 14, 15, 16, 17, 18, 19.
Davis's formula (formula given in Fullam and Hart) was used for computing column 9.
Computations were made for every 500 yards and the columns completed by interpolation.
