I would use, as I do for most hunting with my .22, CCI's Velocitor. A 40g hollow point (large hollow) traveling some 200fps faster than normal .22lr rounds, still has a bit more than 100ft/lbs energy at 100yds, and much more accurate than Stingers, and about as accurate as any other round I've ever used with success.
