I've read it's almost identical to 5744, which is what I use for my 410gr Sub-X load. I used Unique for my 405gr cast bullet loads since I'm running low on 5744. I haven't been able to find 5744 or Trail Boss locally so I might have to pick up some Buffalo Rifle if I see it, looks to be more available than the first two.
