Terry Wieland just did an article where TB beat out his previous choice in some cartridges, but not others. Luck if the draw, I suppose.
I've been meaning to try it in some other rounds, but haven't so far. TB lets you get way lower than the 60% rule for 4895 I believe.
JB and some guy in the latest Hodgdon Annual made up .22 mag-level loads in the .223 with TB, with accuracy comparable to good .22 mag ammo, that is to say well under an inch at 50 yards.
Years ago I used SR4759 for some reduced loads, but recall the occasional hangfire. The .32/20-level load in my .308 was deadly on chucks and one fox, but the flat-nosed HP had a pretty loopy trajectory.
