This weekend I loaded a few odd lots of bullets in 9mm and 45. And prepped some 243 brass to use some powder that I inherited from my Father who passed away almost 2 years ago now. I got some H414 as well as some H450, which I believe is not even being made anymore. I have load data in some of my older manuals and would like to try them just for giggles, if he liked it there was a reason.
