One of the most dangerous mistakes to be made in reloading is to use too much powder or use the wrong kind of powder in a given cartridge. Therefore, deciding on the type of powder to use and the amount of that particular powder is something that should be taken very seriously. DO NOT begin reloading unless and until you have a thorough understanding of the specifications for the powder and cartridge you will be using.
This manual lists the minimum and maximum charges for every powder that is suitable for each cartridge. You should always start at the minimum powder charge and work up slowly and methodically. If you have a powder that is not listed for use in a given cartridge in this manual or another manual, then do not use it! In other words, if the powder is not listed, then it is not suitable for use in that cartridge.
The single biggest danger in using the incorrect type of powder is loading a powder that burns too fast for the cartridge. Excessively fast burning powders, especially when combined with heavier bullets in large cartridges, can cause serious injury or death. ALWAYS take care and double check both the amount and type of powder that you are loading into your ammunition.
And NEVER mix powder types!
