Smokeless Powder For Sale. Buy Gun Powder For Sale Online Free Shipping. Smokeless powder is a kind of propellant used in guns and artillery that, compared to gunpowder, creates less smoke and less fouling when shot (“black powder”). The combustion products are mostly gaseous, while black powder produces around 55 percent solids (primarily potassium carbonate, potassium sulfate, and potassium sulfide).

In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material that is characteristic of black powder and causes the barrel to rust. Smokeless powder is not truly smokeless, despite its name. While smoke from small-arms ammunition may be negligible, smoke from artillery fire may be significant.
