Phil,
+1 on 22brguy response, unless you do offer a goodly number of 400+ shots which seem not to be the case, and the 223AI ammo is cheeper - your son, as my 2 sons, will likely shoot more and in the process learn more -we tend to shoot less as we have become patient inour shooting as we have gotten older.
Thus the potential of higher volume shooting, i would suggest the 223AI as you have the longer distances well covered.
if still confused -- undecieded- will you adopt me?
