Inherently, reloading ammunition is dangerous. The application of a little common sense will go a long way in keeping you out of trouble. As usual, with any reloading data, the components and charge weights used here were safe in the rifles they were tested in, and any change of components could result in dangerous pressure. So, please, if you are new to reloading, go out and buy one of the many excellent reloading manuals that are available. Some are available free of charge from the many components manufacturers, or from their websites.
