Hodgons and IMR are two different and seperate powders. Do not think they are the same. They are made by two different companies and don<t use loading data interchable,they do not!!! Just because the numbers are the same there are not. In some loading manuals they just use one type of pjowders made by one certain companies. Look up a hodgons manuals they have a lot of other companies loads in it also. vangunsmith
