One of the pistoleers I compete with has the CZ 762 x 39 and loves it. Should be good to 175 yds. or so and has enough power in case of a less than perfect shot whereas the 357 may be marginal past 100 yds. Just my opinion.Lots of affordable entry level rifles out there. Don't forget lots of 243 and 7mm08 in youth guns. Maybe have him hunt a yr with your 357 and if he grows enough he'll fit into some of the other entry level youth guns.afish4570
