IMPORTANT POWDER INFORMATION

Important Things to Know About Powders and Your Caliber and Cartridge Case

You must know that the slower the burn rate powder, the higher the powder load, for a given muzzle velocity in a given barrel length of a given bore diameter, with larger case capacities. Moreover, it is important to remember that the quicker (faster) the burn rate powder, the higher the velocity for a given powder load, and a given bore diameter.
This diagram is from page 183 of my book.
Therefore, you know that the larger the bore, the quicker the powder must be for a given muzzle velocity, and a given powder weight.  This is where using V.M.D. (volume measure density) charts come in handy to a reloader.
