In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.
James Monroe Ingalls (January 25, 1837 – May 1, 1927) was an American soldier and an authority on ballistics. His tabulations on ballistics was the authoritative source for over 100 years. His tabulations on ballistics was the authoritative source for over 100 years.
This was due to a combination of slightly higher velocity, a similar Ingalls ballistic coefficient to the M-193 bullet (0.245 vs 0.265), and the superior penetrating ability of solid cold-rolled copper bullets vs jacketed lead bullets given an equal sectional density.
A ballistic chronograph or gun chronograph is a measuring instrument used to measure the velocity of a projectile in flight, typically fired from a gun or other firearm. The instrument is often useful for tasks such as gauging the utility of a firearm or safety of non-lethal projectiles fired from items such as a paintball gun or BB gun .
Sectional density is used in gun ballistics. In this context, it is the ratio of a projectile 's weight (often in either kilograms , grams , pounds or grains ) to its transverse section (often in either square centimeters , square millimeters or square inches ), with respect to the axis of motion.
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
Ingalls, 71, who lives in Long Beach, was 67 when he said the Reds let him go and “hired a 27-year-old kid to do my job,” he said. He filed an age-discrimination suit against the team that was ...
