That's probably the sensible thing to do, the loose material in the frame is making me a little nervous about it's integrity.... Will give the bb another go before writing it off though
What kind of BB is inside? Did you try Sheldon's improvised method? Vice (LBS or a neighbour with a well equipped garage)? The loose material could be a leftover from brazing or whatever, a lot of frames have something rattling inside..
Doesn't have to be dead, wait til you get the bb out to inspect and make the call.
