May want to bring a couple sand bags to get a bit more upright and not sure if it would help but I usually use a 10 round magazine when at the range to keep the magazine off the bench when using bags if you would push the gun a bit more forward. Good to get them interested in shooting while young. Was at the range yesterday and someone brought a guy, probably 42 years old that had never even shot a .22lr before but he just inherited one so was out shooting.
