If you are reloading ammunition, and you used powder that burns faster than the specification for your bullet and cartridge, your ammunition could explode, leading to possible grievous injury on your part. You could also use powder that burns slower than called for by the specification, in which case, your ammunition would fail to adequately propel the bullet, or it might jam in your firearm.Commercial nitrocellulose/nitroglycerin powder (smokeless powder) must be matched to the ammunition and firearm. The powder manufacturers publish "reloading guides" for their powders, and many of them can be found on the internet.There is no excuse for injuries resulting from incorrect reloading of ammunition. Always use the reloading guides, and even then, work very carefully and be alert when shooting.
