I confessed on this board years ago, that I am not a science guy. I am just a reloader with 50 years of experience with 2400 powder, both the Hercules and Alliant versions. When folks start to throw around data, charts, waves etc. I just drop out.
I will say there is nothing in my experience that validates what the fellow says about 2400 as true. Maybe I have had my head up my wazoo for the last half century, but I am calling BS on this guys powder punditry.
