Some say it's better to be lucky than good. I would agree. I have taken two grouse, both while deer hunting. One was at about 20 yards with a full-rifled scoped 870 12 gauge and the other was with a 35 Remington at about 15 yards. Both times I put the cross-hairs on top of the birds head, figuring I would take the head off or miss clean. I know I'm not that good a shot, but I got lucky both times. Both birds looked like they came out of the Tyson or Purdue wrapper after cleaning. Nice to not have lead in your mouth!! Aim small and the .22 will do fine.
