Yes- check with IMR/Hodgdon about using TB in shotshells. I read something about this, a while back (can't remember where), and seem to recall that the loads were considerably lower than the method of loading rifle with that powder would suggest.

When I started loading balls and slugs, I used the slowest powders & lowest pressures generated with shot loads in Lyman's shotshell book. I then carefully crept up in loads, using a chronograph until I matched the speed of the heavy Black Powder loads, ie: 5 and 7 dram loads. I found 4756 to be a good powder for this and it also was quite accurate, even in the smoothbore.

In strong guns, Ed Huble has found H4227 to be quite good as well, and it increases the 'performance' of these guns considerably.
