Smokeless Powder
Modern Nitrocellulose powders have come a long way since then. Today there are single-base and multi-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. Both types have their advantages and are widely used in small arms ammunition, and both types are available to reloaders. At the time of this writing, Winchester/Olin and Alliant exclusively produce multi-base powders, all VihtaVuori and most IMR powders are single-base (700X and 800X are the multi-base IMR powders that I know of), and Accurate and Hodgdon offer several powders of each type.
SINGLE-BASE POWDER
Single-base powder consists of colloided NC with other materials added to obtain suitable form, burning character, and stability. Several single-base propellants are in use today.
MULTIBASE POWDER
Multi-base powder uses NG and/or NQ in addition to NC as explosive ingredients. Such propellants are commonly called double-base (NC and NG) and triple-base (NC, NG, and NQ). One double-base and one triple-base propellant are in use today.
