Myself I'd happily use Unique because I value all the decades of use and praise it has got from users and devotees but I'm not going to pay what I see it going for everywhere when I have pounds and pounds of other powders that do work. I didnt load for my 44 mag or Special until all of the BS happened and had bought alot of powder before it all happened. If I found some at a decent price I'd happily try Ynique, or any of the other tried and true powders for any of my calibers. I'm just trying to work with what I have on hand.
