  Building on previous work by the same authors, we show that certain ideals
defining Gorenstein rings have expected resurgence, and thus satisfy the stable
Harbourne Conjecture. In prime characteristic, we can take any radical ideal
defining a Gorenstein ring in a regular ring, provided its symbolic powers are
given by saturations with the maximal ideal. While this property is not
suitable for reduction to characteristic $p$, we show that a similar result
holds in equicharacteristic $0$ under the additional hypothesis that the
symbolic Rees algebra of $I$ is noetherian.
