I also bought some TU-7000, I wonder what data you finally settled on?
I used 56 grains under a 180-grain Hornady flat-based spitzer for about 2,689 fps. That combination is about as old-school as you can go while still using smokeless powder but I killed a smallish black bear with it with one shot at 353 yards.
I'd buy more of that powder if I could find it. I used a max load and I'd really like to find data that pushes it harder than I did, but all of the data I could find was pretty conservative.

Years ago I got a deal on a case of RWS uniclassic 180 grain. After buying TU7000, I pulled one of the RWS bullets and weighted the charge. It was 54.5 grains of an unknown powder that to my eye looked like TU7000.
I then worked up a load with tu7000 and stopped at 55 grains with a Federal fusion 180 grain so flat base with cannulure. The point of impact was the same as the uniclassic, accuracy is around an inch.
I still have 2 cans left and I'll try to use them with a round nose Sierra or Hornady once they come back. But I'm in agreement, if it becomes available again I'll buy more.
