[QUOTE="Roninco, post: 2139918, member: 114195"] I find it takes about a 1% powder charge reduction loading fired brass to get the same velocity as new brass. Accordingly, if you work up a load using fire formed brass then increase the load about 1% to get approximately the same velocity with new brass. The increased charge provides the necessary pressure to fire form the new cases. This of course assumes you have no pressure signs in either load. As stated earlier, it is important to know how much you are resizing your cases. This will prevent over sizing the brass, lengthen case life, and provide better consistency. [/QUOTE]
