I was testing almost a dozen different types of .22 ammo a few weeks ago with a buddy using our CZ's and Ruger 10/22's. We came across the
CCI Quik Shok's which do wonders on gophers and turned into our ammo of choice for getting explosive results
It's a high velocity segmented hollowpoint, quite literally shreds gophers. Try them out, you won't bother with Stingers again.
