If you could only have one...

Were I to settle on a powder for both handgun and rifle, I'd have to go with Alliant 2400. 

That would allow me to run cast bullets in my big rimmed cartridge rifles like .30-30 and .45-70.

That would be my first choice if I didn't have non-magnum handguns to feed. As it is, it works great in my .480, 30-06's, 8mms, .308s, and .303. Unique works better for me in the 6.5x55- go figure.

I didn't say all.  But it worked just fine in Model 94 in .32 Win Spec. 

I reload a mix of different stuff, so one size doesn't fit all.

That .45 AR Unique load is at least 3 grains above the maximum I've seen anywhere else. And their hot loads weren't confined to Unique powder; as much as I like SR4756, Speer's top SR4756 loads from their #8 manual are too hot. In fact, a buddy of mine got a later printing of the #8 manual than I did, and the SR4756 loads had been removed - he had blank spaces where I had data.

I have a gut feeling that something happened that they won't talk about.

FWIW, the DuPont manuals from the same time frame provided much better maximum load data, IMHO.

Yup.  Waaaay over what I'd ever consider putting in a 1911.  That's why I have a crafty plan to try to slowly approach these performance levels with my 5" 625-2 with new .45 AR brass.  I'd shudder to think what would happen in a crunchenticker.  Hmmmmm...  Maybe a .460 Rowland conversion.  Then I could still use ACP and AR brass in it.

Wouldn't work in my 32swl or 32-20.  Would be marginal in my 38special.
