Situation:

I have a son who is 11yrs old and growing fast. I want to buy a FLAT shooting round for long distance...out to 500yds but with the lightest recoil possible for him. Once he outgrows the gun the wife will be using it. It will be primarily for Deer. I shoot the time tested .06. Can anyone give me a comparison of the felt recoil for the above calibers. Again, I can only compare to what I shoot the 30.06. So when giving me your opinion, please keep that in mind. Example: Would you say the .260 is half that of an 30.06? I shoot 165grn's and reload. My son does not like the recoil of my 30.06. I can understand, it's not that fun to sit down and shoot 75-100rnds. Thanks for the help.
