I started my son with a 270 and 100 grainers loaded 'soft'. As he became accustomed to those and was shooting well, I switched to 140s, again loaded soft. When it came time to hunt, I gave him mid-to-full loaded 140 A-Frames and he had no trouble bagging his first moose. He had just turned 10.

I would bet that you could load those same 130s up another 400-600 fps and he won't even notice the difference with 'hair' in the scope.

Sometimes, the air you 'let in'matters less than the air you 'let out'.
