Burn rate. The burn rate of the powder will greatly affect the peak pressure generated by the powder charge, and is important to match to the type of load (standard -vs- magnum), the bullet weight, and other factors. Typically, non-magnum loads utilize faster burning powders, where magnum loads utlilize slower burning powders. Density
