What is the recipe for smokeless gunpowder?

In 1884, Paul Vieille invented a smokeless powder called Poudre B (short for poudre blanche, white powder, as distinguished from black powder) made from 68.2\% insoluble nitrocellulose, 29.8\% soluble nitrocellulose gelatinized with ether and 2\% paraffin. This was adopted for the Lebel rifle.

What is modern smokeless gunpowder made of?

There are two basic types of modern smokeless gunpowder: single and double base. Single-base smokeless powder is made from nitrocellulose. Double-base smokeless powder is a combination of nitrocellulose and nitroglycerin.

Can you make homemade smokeless powder?

Yes, but there are many types of what is collectively called “smokeless powder”. The most common component is nitrocellulose which can be be made by treating cotton (so-called cotton wool, though it contains no wool) with nitric acid in the presence of sulfuric acid as a catalyst.

What kind of gunpowder is used in shotgun shells?

Flake Powder They are used mostly in handgun and shotgun cartridges. Because of their shape, they can stack up when measuring, making it difficult to meter with precision. This leads to reduced consistency when reloading cartridges with flake powder.

What does +P in ammo mean?

Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
