I have been reloading 125Gr. hollow points in my 38 Special. I have been using a load of 6.5 grains of IMR800X with fine results. I just purchased Hornady 125 Gr.XTP bullets and I read in my Lee reloading manual a seperate section for the Hornady XTP bullets of which it does not list IMR800X powder. I have also noticed that my Speer,Lyman, and Sierra manuals do not have a seperate section for XTP bullets. Is there any differance or need to alter my load?
