Here's the thread in which BD1 reported his results with Unique at 1030 fps with 413-grain cast bullets:

And here's an interesting quote from last spring:

A link to the post and thread with that quote:
http://450bushmaster.net/viewtopic.php?f=2&t=597&start=16Trying to work up this load is like trying to ride a unicycle on a high tight rope; there are lots of things that have to balance, and there is the possibility of disaster if they don't. I would be inclined to follow wildcatter's advice and stay away from reduced loads with double-based ball powders. I've worked briefly with a new powder, Alliant Power Pro 300-MP, that is described as being a bit faster than Lil'Gun in burn rate. With loads that were less than case filling, there were no ka-boomy pressure problems, but there were some click-pop fizzles with lots of unburned powder. I took those as a sign that I was on the edge of perhaps major difficulties, and quit trying to use that powder for a job it wasn't designed to do.
There exists the possibility of real trouble when going outside of lab-tested data. Until I find out for sure what's happening, I'm not bashful about sandbagging the rig and staying behind a big tree while pulling the trigger with a long string.
