One attraction of TB is the ease with which accurate low-power loads can be created for CF rifles using jacketed bullets. Charles Petty has done a couple articles on this with really excellent results.
I made up some .243 loads with 100 Sierra blems I bought from Graf's. It grouped 3 in about 1 1/2" at 100, first try, at an assumed velocity of about 1500-1600fps; a great practice load with no fiddling necessary. They land just a bit below full power loads.
If my .44mag loads group okay, I'll have a pleasant plinker load for my low wall at less than a quarter a pop, with no casting necessary, about the price of bulk 9mm.
Other powders may be a bit cheaper, but TB is useful in a bunch of stuff, requires no fillers, and is whoopsie proof. I've got a couple of small jugs, but am going to get a 5-pounder when I can find a good deal.
