Thanks, that's great info. Some folks in those posts are using one pass to go from .30 to .375 but they are modifying expander plugs, buying new ones etc. I'll give it a go with what I have. This is just a one time and done deal so buying new stuff just for these 100 cases is sort of counter productive. The other good info is that those who do fire form are using 5-6 grains of Unique, not 13, and reporting perfectly formed cases. Hmm, I'd better go back and tweak the Fudge Factor Findabulator quite a bit...
