22-250 all the way.
not that a 308 wouldn't work,but a 62 tsx at 3500 will work better .
Better than what? Any 308 load? Certain 308 loads? Work better for a kid?
Ive shot a few with a 308 and never felt "under"gunned. Ive shot a few with a 22-250 also. Most factory 22-250's are still 1:14 arent they? The 62tsx is probably not going to work in most guns the OP would buy anyway so the case would have to be made for the 53gr.
Also, no one asked if the OP handloads... If not, it throws the ball back in the 308's court.
I gave my kids 243's and wouldnt change a thing except had them rebarreled to 1:8 from the start.
