Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants.
Hodgdon distributed spherical powders HS-5 and HS-6 for shotguns and H110, H335, H380, H414, and H450 for rifles. [10] DuPont added IMR 4895 to their retail distribution line in 1962, and added IMR 4831 in 1973 when supplies of surplus H4831 were exhausted. [11] Hodgdon then acquired newly manufactured H4831 from Nobel Enterprises in
Hodgdon H110 smokeless pistol powder. The properties of the propellant are greatly influenced by the size and shape of its pieces. The specific surface area of the propellant influences the speed of burning, and the size and shape of the particles determine the specific surface area.
St. Marks Powder is a subsidiary of General Dynamics Ordnance and Tactical Systems manufacturing ball propellant [1] in Crawfordville, Florida.St. Marks makes about 6,000 tons per year, [2] making it the world's largest producer of propellant. [3]
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
However, today, with the availability of a wide range of powders, velocities gains of 150–200 ft/s (46–61 m/s) can be realized. Acceptable bullet weights for the .375 H&H Magnum range from 200 gr (13 g) to 380 gr (25 g). The lighter bullets, those weighing 210 gr (14 g) to 235 gr (15.2 g) are suitable for lighter plains game.
According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,500 yards (1,370 m), decrease wind deflection on bullets in flight and use Hodgdon H1000, a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of −25 ...
