Was doing some research to try and help out with some data on another thread and found a recall notice on Alliant's web site concerning Unique Powder. This is an older recall, July 6, 2005, but a search of the forums found no posts about it. Considering the nature of the recall, I thought it was worth mentioning. The substitution of Bullseye where Unique is called for could lead to disastrous results. Text of the recall is below.
