I was wondering if any of y'all could tell me what powder this might possibly be or at least point me in the right direction, especially those of you loading big bore revolvers. I pulled a bullet from a commercial round after I discovered it shot like a laser out of my Redhawk with good speeds over the chrony.
The powder granules are tiny short, cylinders with a hole going through the length like little spools. I remember reading an article in the Propellent Profiles column of Handloader with these particular physical characteristics, but I don't recall right off hand what it was.
Just thought I would take the lazy way out and ask before I went back and searched through 10+ years of Handloader back issues.
