For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
Crimping the case around the round ball may be necessary to prevent ball movement during recoil. As with most firearm cartridges, the .45 BPM can be loaded in a variety of configurations. A minimal 40 grain load of black powder is recommended as this is the upper limit of the .45 Colt cartridge.
The new 45-70-500 loading was recorded with a muzzle velocity of 1315.7 feet, and generated 1525 ft lbs of energy at 100 yds, and 562.3 ft lbs of energy at 1,000 yards, with a maximum range of 3,500 yards.

Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
Muzzleloading firearms generally use round balls, cylindrical conical projectiles, and shot charges. In some types of rifles firing round ball, a lubricated patch (see Kentucky rifle) of fabric is wrapped around a ball which is slightly smaller than the barrel diameter. In other types of round ball firing rifles, a ramrod and hammer is used to ...
Buck and ball was a common load for muzzle-loading muskets, and was frequently used in the American Revolutionary War and into the early days of the American Civil War. The load usually consisted of a .50 to .75 caliber round lead musket ball that was combined with three to six buckshot pellets.
