the dumbazz questions are coming. I'm looking at HODGDON UNIVERSAL powder for SHOTGUN and HANDGUN. For 9mm Lugar it says...Charge...5.0, 115. gr.GDHP, Case...Win., Primer...CCI 500, C.O.L. 1.125, 1149 Velocity, this is what is on the container. I have a Lee pro 1000, it says to use CCI or Winchester primers. Why can't I use Federal primers? Why can't I use a mixture of casings that I bought from, ONCEFIRED? I know there has to be different recipes. Do I need to go strictly by the book? Not mix anything. Wanna kill these ads? We can help!
