Burn rates of smokeless powders

The Relative Burning Rate of Powders. By Roberto Serino. Most reloaders wonder whether burn rate charts are really meaningful, or meaningless. As a matter of  Smokeless powder is the name given to a number of propellants used in firearms and artillery Smokeless powder burns only on the surfaces of the pieces. Larger pieces burn more slowly, and the burn rate is further controlled by  Powder burn chart - Reloading Data Hodgdon Powder Co Inc The Brand Thats True Smokeless powder for reloading and Pyrodex - 

Black powder is different from smokeless in two respects: in the first place, it is a het- erogeneous system and not homogeneous: the combustible (carbon) and the  proof that all smokeless powders burn in layers, the scientific finding. It also powders). 3) Mathematical model and burning rates: Vieille, using the proof of. Powder Burning Rate Chart shows 107 powders from the fastest to the slowest.

Shape and size have a profound effect on the burning rate and power generation of a powder (Meyer 1987). Common particle shapes of smokeless propellants  Smokeless powder does not detonate like high explosives as it has a controlled rate of burn and differs considerably in its burning char- acteristics from common “  

Hodgdon surplus 4831 cost about a dollar a pound when I first began reloading about 38 years ago. H4831 is listed at the slow end of the burn-rate chart. It's most suited for full-case charges in the .270 Win., 7mm Rem. Mag., .30-06, or .300 Win.

Flake powder is typically coarsely cut and bulky (i.e., less dense) compared to stick or ball propellants. Burn rate is significantly affected by the granules' total

The following powders are listed by their approximate burning rate, from "fastest" to "slowest". It must be clearly understood that burning rates are not linear. Burn rate is important, however, when you are loading magnum vs. non-magnum rounds. Typically, a non-magnum load will use faster burning powders while a magnum cartridge will need slower burning powders. Magnum rounds need to generate greater power. Therefore, they use slower-burning powders, which creates peak pressure for a longer timeframe.

Typically, a non-magnum load will use faster burning powders while a magnum cartridge will need slower burning powders. Magnum rounds need to generate greater power. Therefore, they use slower-burning powders, which creates peak pressure for a longer timeframe. Many ball powders will burn at lower temperatures, which should extend the life of a barrel. Ball powder burns at about 3,200 to 3,300 Fahrenheit, while other powders only reach a max of about 3,400 Fahrenheit. The difference in temperature might seem minimal but it can make a difference over thousands of shots.
