My son is 6 year old. I was looking at the ruger mkII compact .308 for his because it is short. To reduce the recoil I was going to use Remington managed recoil loads and a simms recoil pad, it will be a gun that will stay with him as he grows. If the products listed does what the advertise, this should be the recoil down to at least a .243 caliber recoil. Is this still to much gun? Should I stay with a .223 caliber? Any help would be appreciated. He loves to hunt and fish!!!
