Given the following criteria what would you guys say is the best general use pistol powder for standard/medium loads in the most common rounds(9mm, 38/357, 40 S&W, 44 Mag, and 45 ACP? It is a given that no one powder will do everything in all calibers.

1. Reasonable case fill to reduce the double charge risk.
2. Reasonable economy in many calibers (grs. per round).
3. Usable with jacketed, plated, and cast bullet loads.
4. Functions well through measures for progressive loaders.
5. Burns fairly cleanly.
6. Produces reasonable accuracy.

I have some thoughts, but was curious what others had experienced.

Thanks,
