The majority of grouse I've shot in the last 15-20 years have been with either a .22 pistol ,currently a S&W 422 , or more typically an old Benjamin .177 pump pistol, head shots.
It's nice and quiet , no , you can't have it!
I did get a couple this year with the bow and small game heads though.
Being quiet and not spoiling "bigger" plans is key.

"Camping places fix themselves in your mind as if you had spent long periods of your life in them.
You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
