Pick whatever shoots best
My old man and I spent many years picking off woodchucks in our hayfields with a .22.
Groundhogs are tough. You're going to need to go for head shots, or you'll just end up wounding the critter, even with Stingers or other higher-power .22 rounds.
So pick whatever your gun shoots most accurately. Expansion and velocity don't matter a whole lot when you're destroying brain tissue.
On the other hand, it's my experience that no amount of expansion or knockdown power from a .22 round is going to make much of a difference if you hit a groundhog anywhere else.
