Try something just short of max with Unique or maybe just 5.0 of Bullseye and see how it does. It might be easier than tinkering with alloys. Of course, there is nothing wrong with working on a better alloy, it's just that better alloys cost money and since you already have other powders, I find it cheaper and easier to adjust powder charges.
Now that you mention it I've shot some reasonably hot loads with unique in .38 spl and .44 spl with no leadind problems.

I want to keep my .45 ACP loads in the 900 fps range so I'll try Unique as well as experiment with casting alloy. Thanks.
