I am loading 45 ACP and 9mm Luger. I have Bullseye (BE), Titegroup (TG) and W231 powders available, and want to develop mid velocity loads for each caliber with these powders. I'm 'shooting' for 750 - 800 fps out of the 45, and 1025 - 1075 fps out of the 9mm. Reviewing all the manuals and data I have for these calibers and powders, I wanted to gain more insight into what I perceive as inconsistent information for the charges suggested for these powders for loading 9mm. Experience/knowledge/clarification from you long time reloaders is most appreciated for the question that follows.
I know that the 231 is the slowest powder of my group, followed by TG, and BE being the fastest. Looking at the 230gr FMJRN data available, it consistently indicates that the charges for the BE are less than those for the TG, and the TG are less than those for the W231 at the same indicated velocities or pressures. This makes perfect sense to me based on the 'speed' of the powders.
Now when I look at the 9mm tables from these same sources for the 115gr FMJRN, I find that in many cases, the suggested charges for TG are LESS than for BE.
I don't understand why this is the case for 9mm, and want to understand this before I load up the 9mm.
Thanks;
John
