Having owned both and shot both I'll vote for the 7MM-08 only because IMHO felt recoil seems to be less in the 7MM-08. When I've had rifles that are about 99% identical I always thought the 08 just didn't seem to kick as much or felt that way. The CM seemed more snappy if that makes sense?? But since you said for a young hunter it may make a difference??
+1
I also have owned both, just checked ammoseek and there is plenty of 7mm-08 ammo starting at $19.75 a box.
