There are many different smokeless powders
available in a wide variety of burning rates. Powders are available in two
types of composition; Single base and Double base. Single base powders are
made from a straight nitro-cellulose composition. Double base powders contain
both nitro-cellulose and a percentage of nitroglycerin. Powders most commonly
used by the reloader are available in three types.
1. Extruded or Tubular
This type of powder is most commonly used in rifle cartridges, and is usually
single base. However, there are a few which are double base. Burning rate
is controlled by composition, grain diameter and length, web thickness, and
deterrent coating. Extruded powder can vary greatly in appearance and grain size.
2. Spherical or Ball
Powder
Spherical powder can look like tiny round balls or the grains can be flattened. The grains can vary in size, shape, and
color. The burning rate of spherical
powders can range from a fast pistol powder to very slow rifle powder. All
spherical powder is double base and burning rate is determined by chemical
composition, grain size, and deterrent coating. Spherical powder, in general,
is harder to ignite than extruded powder, therefore magnum primers are
recommended in certain loads.
3. Flake
This type of powder is usually double base fast burning, suitable for pistol,
shotgun, and light sub-velocity loads in rifles. Flake powders in slower
burning rates suitable for rifles are not available in this country, but
have been used in Europe.

*** This is the approximate order
of burning rates for established brands of powder from fastest to slowest. Powders tend to switch positions especially those close in burning rate,
depending upon the characteristics of the cartridge and other variables. Be sure to refer to manufacturer loading data manuals for proper
charges.
