I use Hunter in my 270. With 140 SST. 3030-3050 fps max load of 55gr was luckily the sweet spot for accuracy and speed..
Had them 3100 fps but accuracy suffered and it was over max (56 gr. 3108-3122 fps)

I think I’m down to last 100 or so of the sst. Bought 500 of Sierra game changers trying to get better hunting bullet as I hear lots of horror stories on sst.
55 gr of hunter, CCI primers, 2.665” base to ogive

130 ttsx with 56 gr of hunter 3100 +/- fps.
BTO 2.670

Obviously you want to or can make reduced loads for the kid.
Probably stick with 130s at closer to min/start?
I have some 150gr Ballistic tips at 2800fps and have more of push vs snap

All of them do something better than the 30-06, but none of them do everything as well.
