A 223 AR-15 with a good brake has no real recoil. But the bolt is slamming around. How this translates to impulses to your shoulder I don't know. I would describe it as 'no real recoil". Can you try a braked AR? There are guys around you that have one.
A 223 target rifle will shoot accurately to 1000 yards (with 80 gr bullets) I have done it. It weighs 12 pounds and has no real recoil, either.
