My grand daughter shot up like a weed the last two years. When she was a puny 10 yr old she shot 85 grain pills from a 243. This fall I had her shoot some of my 140 grain 260 Rem from a nearly identical rifle. After her first group I told her she could go back to the other rifle if she wanted to. She said "What other rifle?". She Hadn't even noticed she was shooting the 260
It's not rocket surgery, for crying outside!
