I'm not aware of a 7.63 loading by S&B. They do load a 7.62x25 which is dimensionally identical, but much hotter. Conventional wisdom says this loading is suitable only for the Tok and CZ-52 since the 7.63 Mauser was quite a bit lighter loaded. S&B specs say their 7.62x25 velocity is around 1650fps IIRC.
The only new commercial 7.63 Mauser on the market that I know of is loaded by Fiocchi.
I bought a couple of boxes about a month ago. Ran a mag through the chrony and was getting in the 1550 fps range. That's about the same readings I was getting with Winchester.
