@Glenda: If you "pull" the mixture from your jacket, then it would be Coincidental. This is really close to the prior attempt to change gunpowder to sand. The difference is that it isn't possible to get sand into the bullets, but it is possible that you came prepared. This is a small difference and I recognize that this may be entirely subjective - hell, I may be wrong. For comparison, if the gunpowder in the bullets were transformed into 'stale' gunpowder, or contaminated gunpowder, something that could have occurred at the bullet factory, a bad batch, then it would have been Coincidental.
