You asked for opinions and here is another. Use Unique if you want. It will work, has for years, just not in my guns!

If you want 1 powder to take you from mild to wild, there is only one for revolver loads, again, this is my opinion, SR4756. While I don't have an 8lb keg like Paul, I do have it's little brother, 4lb, and not one of Unique!
