The 25-06 Rem 7600 will shoot better if you son's cheek is touching the stock, not moving back and away when he pulls the trigger.
Worst flinch I ever saw. The kid moved like a boxer avoiding a punch, then slapped the trigger.
Dad's head was stuck in the spotting scope and adjusting the sights with every shot.
"Oops now it's low and left"
I witnessed a similar event at a public site in day at a private range. Guy had his 600 yard elk gun a 7mm mag and was trying to site it in. Seemed to be having problems. I watched him carefully and with each trigger pull (literally) he would close his eyes and move his face off the stock. After firing almost 20 rounds he hit a 3" bull and called it sited in. The rest formed about an 18" pattern with non close to one another.
