EXPERIMENTS IN FRANCE.
It is stated by Captain Jervis, R.A., in the “Rifle Musket,” that “From experiments made in France, Angle for greatest range.it has been found that the greatest range of the common percussion musket, with spherical bullet fired with the regulation charge, was at 25°; yet, by theoretical calculation, it should be 45°; Velocity.also that the usual velocity was some 500 yards per second, whilst in vacuum it would be 19,792 yards per second.
Elevation giving certain range.
“At an angle of from 4° to 5°, the real range was about 640 yards; without the resistance of the air, and at an angle of 41⁄2°, it would be 3,674, or six times greater.”
