I picked up a 243 for my 11yr old and 14yr old daughters last fall. They went from the 22lr to the 243. They handle the recoil without issue. Hearing protection is important also. The big boom noise can be intimidating. You never want to scare a young shooter with too much recoil and noise. That’s a recipe for disaster. It happened to me when I was very young. Dads old 30/30 Winchester walloped my shoulder blade and and scared me. I was just too young.
