Burn rate of smokeless powder

Light charge weights of fast-burn-rate propellants are loaded in small, lower-pressure, straight-walled cartridges. Heavy charges of slow powder go in large, bottlenecked, higher-pressure rounds. As the cartridge capacity increases and/or the SAAMI pressure limits increase, the best propellant will typically exhibit a relatively slower burn rate.
