There are no bad powders, but there are several that seem redundant (if not identical):
- Herco: does anyone use it? We already have Unique
- Alliant 410: for 410's only....
- IMR4756 and IMR7625: let's at least change the names so we don't confuse them with IMR4759
- The IMR and H "almost identical twins": 4198, 4895 and 4350. H4227 was already dumped and we have survived
- IMR4320 and 4064: choose one
- H4831 and 4831SC: lose the former
- the Win and Hodgdon powders that are the same powder with a different name (e.g. Win231 and HP-38)
