I believe it was Glen Zediker, in his superb book "reloading for competition" stated something to the effect that "only high power shooters will spend $2000 on a match-grade rifle and then dumpster dive for brass..."
If in doubt, throw it out. Cost of new brass is much less than living with a serious injury due to case head separation or the like.
