Hello, Magnum Wheel Man. It is a good powder for low pressure heavy 12 & 20 ga. shotgun loads. I don't have books with me, but there are pistol loads listed & I believe Lyman lists reduced cast-bullet loads using it. The PB stands for poris base.
What I have found it is very good for is duplexing with black powder in metallic cartridges. I have been working with 1 to 2 gr. PB next to primer in the .25-25 Stevens case, filling rest up with 22.5 gr. 3FG Swiss. This leaves bore as clean as a straight smokeless load, with no pressure signs. I plan on experimenting with other black powder calibers in the future. Best of luck!
