While Mule Deer's article in the Oct/Nov 2019 Handloader, ".270 Winchester - Testing New Bullets and Powders" probably doesn't really address the OP's quest for light recoil loads for his young hunter, it does match perfectly to the title of this thread, so I mention it here for those who click on this thread because of its title. It's a very informative article (of course!)
Cheers,
