Ramshot Silhouette works well in all of the cartridges you mentioned except .357 mag. Ramshot publishes no data for .357. I don't know if WAP had .357 data; anyone out there with older manuals may be able to answer that one.
Tried the "Flammable Dirt" (Unique) once, but it caused major fouling and failure in two different pistols in two different calibers. I avoid it like the plague. The garden liked it well enough......
