Reloading 'range-grazed' 9mm last night and found I'd missed two S&B. I deprime manually, so that wasn't an issue but I couldn't figure out why the primers were having such a hard time going in (and that's not a die issue). Turns out they were S&B. Well, they were already primed, so I kept them, but painted their bases with a Sharpie to remind myself to toss them next time.
Dudley - you say you have a primer pocket swager. Your problem would thus seem to be primarily decapping. Here's a thought - the pins are just a length of steel; there's nothing hi-tech about them.
Perhaps your local hobby store has steel rod of the right diameter to fit S&B flash holes - depending on how your dies are set up, it might or might not hold in place.
Alternatively, you could chuck a spare pin into a drill and use a file to reduce its diameter. Bit of a PITA, but then you'd only have to turn down a centimetre or so. That way, the other end would still fit properly in your die.
