I have not noticed that S&B is particularly hotter than WWB, at least in 9mm.
.380, S&B maybe a bit hotter, imho.
.32, I don't shoot a whole lot but I've used (crappy) Aguila, (crappier) Wolf, and S&B.
I didn't notice a whole of difference, except that Aguila is dirty and Wolf is dirty *and* stinky!
I much preferred the S&B. I have no complaints with Fiocchi etiher.
Although I'm sure there's some folks around here with differing opinions.
