That is great that she could shoot like that! Congrats to her and to you, for taking the time to teach her, as well.
I never shot at things close enough to do one hole groups with my 342 or Sheridan Blue Streak. But we were out at 1000 Acres, now a park with signs prohibiting the use of airguns but allowing shotguns, one day shooting balloons tied to sticks on a lake that was over a hundred yards wide. One of the four inch balloons got away and the wind pushed it to near the far end of the lake. I took four shots at it holding over more each time as my shots all fell short. Then my youngest daughter, about nine years old, wanted a turn. So, I set her up with a log for a rest and pumped the old 342 up for her. She settled in and I told her to hold over about six feet, She carefully sighted in and squeezed the shot off. Some time later the four inch balloon went pop. She had the same grin, of job well done, as your daughter. In her forties now and still remembers the day and shot.
Kids require the time we spend with them to have a good image of themselves. More is usually better. This is extremely important when trying to raise a decent caring human being.
Thanks for sharing
