Mine came in the mail yesterday. I spent a couple of hours playing with it last night. It's gonna take a long time to figure out how to use all the graphs and charts and stuff, and to figure out what's significant and what's not. (like does it matter if the powder is still burning when the bullet leaves the muzzle. I assume the shock wave is still accelerating the bullet even after it leaves the barrel, but the efficiency goes down and the muzzle blast goes way up.)
I did figure out something that's been puzzling me about Bullseye powder. Bullseye is not as fast as everyone thinks it is. It is only a little faster than Unique, but it has about 25% more energy per grain than any other powder except Power Pistol -- which used to be called Bullseye 84. (Alliant must take that into account when they assign their "relative quickness" ratings.) That's why its charge weights are so low for target loads, but its performance is better than it should be in 357 Magnum, etc.
BTW, it does have Titegroup powder, and I think I remember seeing HS-6 and a half a dozen Ramshot powders. I have a 8 pound keg of WSF and wish it was included.
