Hodgdon Benchmark Smokeless Gun Powder


As the name implies, this Extreme Extruded propellant was developed for precision cartridges, such as benchrest and small varmint cartridges like the 6mm PPC, 22 PPC, 6mm BR, 22 BR, 223 Remington and 222 Remington. Additionally, it performs superbly in the 308 Winchester with light match bullets like the 147 gr. and 155 gr. versions. With small, easy metering granules, competitors will love how it flows through progressive presses.

Benchmark Smokeless gun powder consists of nitrate (single-base powders), oft combined with up to fifty p.c trinitroglycerin (double-base powders), and typically trinitroglycerin and nitroguanidine (triple-base), preserved into little spherical balls or extruded into cylinders or flakes exploitation solvents like ether. alternative minor ingredients, like stabilizers and flight modifiers, are additional. Double-base propellants area unit common in pistol and rifle ammunition. Triple-base propellants area unit additional common in artillery guns.

The reason that Benchmark Smokeless gun powder  is that the combustion product are chiefly vapourish, compared to around fifty fifth solid product for black powder (potassium carbonate, metallic element sulphate etc).

Benchmark Smokeless gun powder burns solely on the surfaces of the granules, flakes or cylinders – delineate as granules for brief. Larger granules burn additional slowly, and therefore the burn rate is additional controlled by flame-deterrent coatings that retard burning slightly. The intent is to manage the burn rate so a additional or less constant pressure is exerted on the propelled projectile as long because it is within the barrel therefore on get the very best rate. Benchmark Smokeless gun powder has the most important granules, up to thumb-sized cylinders with seven perforations (one central and therefore the alternative six in a very circle halfway to the surface of the cylinder’s finish faces). The perforations stabilize the burn rate as a result of because the outside burns inward (thus shrinking the burning space the within is burning outward (thus increasing the burning surface area, but faster, therefore on top off the increasing volume of barrel given by the outbound projectile). Fast-burning shooting iron powders area unit created by extruding shapes with additional space like flakes or by flattening the spherical granules. Drying is typically performed below a vacuum. The solvents area unit condensed and recycled. Benchmark Smokeless gun powder The granules are coated with carbon to stop electricity sparks from inflicting unsought ignitions.


Military commanders had been whiny since the warfare regarding the issues of giving orders on a tract that was lined in thick smoke from the powder employed by the guns. a serious success was introduced once nitrocotton, a nitrocellulose-based material, was 1st introduced by Christian Friedrich Schönbein in 1846. He additionally promoted its use as a blasting explosive.

Benchmark Smokeless gun powder was additional powerful than powder, however at an equivalent time was somewhat additional unstable. This created it unsuitable as a propellant for little firearms: not solely was it dangerous below field conditions, however guns that might hearth thousands of rounds exploitation powder would be “used up” when solely a number of hundred with the additional powerful nitrocotton. It did realize wide use with artillery. However, among a brief time there have been variety of huge explosions and fatalities in nitrocotton factories thanks to lack of appreciation of its sensitivity and therefore the means that of stabilization. nitrocotton then went out of use for a few twenty years or additional till it can be tamed; it had been not till the Eighties that it became a viable propellant.

Benchmark Smokeless gun powder revolutionized the effectiveness of little guns, for many reasons. First, it gave off virtually no smoke. when a number of shots, a soldier with black powder ammunition would have his read obscured by an enormous pall of smoke unless there was a powerful wind. Conversely, a crack shot or alternative hidden shooter wouldn’t run away by a cloud of smoke over the firing position. Further, it had been 3 times additional powerful than black powder, that gave additional power from less powder. the upper speed meant a blandish mechanical phenomenon and thus additional correct long vary hearth, dead set maybe a thousand metres within the 1st Ballistite rifles. Since less powder was required to propel a bullet, the cartridge can be created smaller and lighter. This allowed troops to hold additional ammunition for an equivalent weight. Also, it’d burn even once wet. Benchmark Smokeless gun powder ammunition had to be unbroken dry and was nearly always hold on and transported in watertight cartridges.
