Ammunition handloading has become increasingly popular in recent years. This page discusses properties of smokeless powder and offers recommendations for its storage. This information is intended to increase the knowledge of all concerned individuals and groups regarding smokeless powder.
The statements and recommendations made are not intended to supersede local, state, or Federal regulations. Proper authorities should be consulted on regulations for storage and use of smokeless powder in each specific community. Smokeless powders, or propellants, are essentially mixtures of chemicals designed to burn under controlled conditions at the proper rate to propel a projectile from a gun.
The energy released from double-base smokeless powders is derived from both nitrocellulose and nitroglycerin. All smokeless powders are extremely flammable; by design, they are intended to burn rapidly and vigorously when ignited. Oxygen from the air is not necessary for the combustion of smokeless powders since they contain sufficient built-in oxygen to burn completely, even in an enclosed space such as the chamber of a firearm.
In effect, ignition occurs when the powder granules are heated above their ignition temperature. This can occur by exposing powder to: A flame such as a match or primer flash. An electrical spark or the sparks from welding, grinding, etc.
Heat from an electric hot plate or a fire directed against or near a closed container even if the powder itself is not exposed to the flame. When smokeless powder burns, a great deal of gas at high temperature is formed.
If the powder is confined, this gas will create pressure in the surrounding structure. The rate of gas generation is such, however, that the pressure can be kept at a low level if sufficient space is available or if the gas can escape. In this respect smokeless powder differs from blasting agents or high explosives such as dynamite or blasting gelatin, although smokeless powder may contain chemical ingredients common to some of these products.
High explosives such as dynamite are made to detonate, that is, to change from solid state to gaseous state with evolution of intense heat at such a rapid rate that shock waves are propagated through any medium in contact with them. Such shock waves exert pressure on anything they contact, and, as a matter of practical consideration, it is almost impossible to satisfactorily vent away the effects of a detonation involving any appreciable quantity of dynamite.
Smokeless powder differs considerably in its burning characteristics from common "black powder. When ignited in an unconfined state, smokeless powder burns inefficiently with an orange-colored flame.Read more about storing powders here!
Smokeless powders are made in three forms:. Single-base smokeless powders derive their main source of energy from nitrocellulose. The energy released from double-base smokeless powders such as the Vihtavuori N rifle powders is derived from both nitrocellulose and nitroglycerine. Oxygen from the air is not necessary for the combustion of smokeless powders, since they contain sufficient built-in oxygen to burn completely, even in an enclosed space such as the chamber of a firearm. When smokeless powder burns, a great deal of gas at high temperature is formed.
Black powder burns essentially at the same rate out in the open unconfined as when in a gun. It leaves a residue of ash and partially burned powder. If burning smokeless powder is confined, gas pressure will rise and eventually can cause the container to burst. When smokeless powder in D.

Create recipes wherever you are.The stuff that we shooters know as smokeless powder was introduced as a black powder replacement in the 's. Besides generating a lot less smoke, smokeless powder burns much cleaner and more efficiently than black powder, greatly reducing powder fouling and increasing the performance of the shotgun, handgun, and rifle cartridges in which it is used.
It is also much safer to produce than black powder, which has saved many lives over the years. Smokeless powders are nitrocellulose-based propellants derived from experiments with guncotton, which was created in the mid's by exposing wood or cotton fibers to nitric acid.
Gun cotton is not a suitable propellant, but softening guncotton in a mixture of ether and alcohol produced the first, crude, smokeless powder.
Modern Nitrocellulose powders have come a long way since then. Today there are single-base and double-base smokeless powders. Single base powders are based on nitrocellulose alone and double base powders contain nitroglycerine in addition to nitrocellulose, adding to its energy.Vrchat ruby client discord
Both types have their advantages and are widely used in small arms ammunition, and both types are available to reloaders. Smokeless powder does not explode when unconfined, unlike black powder.
In fact, technically, smokeless powder does not explode at all; it merely burns rapidly. Smokeless powders are classified as flammable solids.
This rapid burning releases a huge volume of expanding gasses which, if confined in the chamber of a firearm, accelerate the bullet or shot charge down the barrel, producing a high velocity in a very short distance.
Zero to Mach 2 in 26 inches for most centerfire rifle bullets, for example! The burning rate of smokeless powders is varied and controlled in various ways.
One is by the physical size of the grains, flakes, or spheres of powder. The larger these are the slower the powder burns. Naturally, the exact chemical composition of the powder also affects its burning rate.
A third method is to increase the surface area of the powder grains. The individual grains of many cylindrical powders, for example, are hollow rather than solid cylinders. Another way is by the use of deterrent coatings to slow the burn rate. These coatings retard the initial ignition of the individual powder grains. They may also decrease the burn temperature, which reduces throat erosion in firearms.
Always remember that the burning rate of smokeless powders is not constant. It varies dramatically based on the degree of confinement.If not, please enter your business contact information on the form below and we will add you to our Dealer Locator.

The term is unique to the United States and is generally not used in other English-speaking countries,  which initially used proprietary names such as " Ballistite " and " Cordite " but gradually shifted to "propellant" as the generic term. This article focuses on nitrocellulose formulations, but the term smokeless powder was also used to describe various picrate mixtures with nitratechlorateor dichromate oxidizers during the late 19th century, before the advantages of nitrocellulose became evident.
Since the 14th century  gunpowder was not actually a physical " powder ", and smokeless powder can be produced only as a pelletized or extruded granular material. Burnt gunpowder leaves a thick, heavy fouling that is hygroscopic and causes rusting of the barrel. The fouling left by smokeless powder exhibits none of these properties though some primer compounds can leave hygroscopic salts that have a similar effect; non-corrosive primer compounds were introduced in the s  : This makes an autoloading firearm with many moving parts feasible which would otherwise jam or seize under heavy black powder fouling.
Smokeless powders are classified as, typically, division 1.Best hi fi albums
However, they are used as solid propellants ; in normal use, they undergo deflagration rather than detonation. Before the widespread introduction of smokeless powder the use of gunpowder or black powder caused many problems on the battlefield. Military commanders since the Napoleonic Wars reported difficulty with giving orders on a battlefield obscured by the smoke of firing. Verbal commands could not be heard above the noise of the guns, and visual signals could not be seen through the thick smoke from the gunpowder used by the guns.
Unless there was a strong wind, after a few shots, soldiers using gunpowder ammunition would have their view obscured by a huge cloud of smoke. Snipers or other concealed shooters were given away by a cloud of smoke over the firing position. Gunpowder is a low explosive that does not detonate but rather deflagrates burns quickly at subsonic speed.
Gunpowder produces lower pressures and is about three times less powerful when compared to smokeless powder. Likewise, gunpowder's tendency to produce severe fouling causes actions to jam and often makes reloading difficult. Nitroglycerine was synthesized by the Italian chemist Ascanio Sobrero in Nitroglycerine is also highly sensitive, making it unfit to be carried in battlefield conditions.
He promoted its use as a blasting explosive  : 28 and sold manufacturing rights to the Austrian Empire. Guncotton was more powerful than gunpowder, but at the same time was once again somewhat more unstable. English interest languished after an explosion destroyed the Faversham factory in Austrian Baron Wilhelm Lenk von Wolfsberg built two guncotton plants producing artillery propellent, but it too was dangerous under field conditions, and guns that could fire thousands of rounds using gunpowder would reach the end of their service life after only a few hundred shots with the more powerful guncotton.
Small arms could not withstand the pressures generated by guncotton. Abel patented this process in when the second Austrian guncotton factory exploded. After the Stowmarket factory exploded inWaltham Abbey began production of guncotton for torpedo and mine warheads.
InPrussian artillery captain Johann F. Schultze patented a small-arms propellent of nitrated hardwood impregnated with saltpeter or barium nitrate.Np8 rpo code
Prentice received an patent for a sporting powder of nitrated paper manufactured at Stowmarket, but ballistic uniformity suffered as the paper absorbed atmospheric moisture. InFrederick Volkmann received an Austrian patent for a colloided version of Schultze powder called Collodinwhich he manufactured near Vienna for use in sporting firearms. Austrian patents were not published at the time, and the Austrian Empire considered the operation a violation of the government monopoly on explosives manufacture and closed the Volkmann factory in Inthe Explosives Company at Stowmarket patented an improved formulation of nitrated cotton gelatinised by ether-alcohol with nitrates of potassium and barium.
These propellants were suitable for shotguns but not rifles,  : — because rifling results in resistance to a smooth expansion of the gas, which is reduced in smoothbore shotguns.
InPaul Vieille invented a smokeless powder called Poudre B short for poudre blanche —white powder, as distinguished from black powder  : — made from This was adopted for the Lebel rifle. A particularly good feature of the propellant is that it will not detonate unless it is compressed, making it very safe to handle under normal conditions.
Vieille's powder revolutionized the effectiveness of small guns because it gave off almost no smoke and was three times more powerful than black powder. Since less powder was needed to propel a bullet, the cartridge could be made smaller and lighter.
This allowed troops to carry more ammunition for the same weight.Powder left in the reloader's powder measure hoppers for extended periods, overnight or several days, should be avoided. Powder needs to be stored in original containers ONLY, when not in use. Numerous modern smokeless powders are double base in construction, containing both Nitrocellulose and Nitroglycerine.
