Yes, he IS and, a good Shot, too. Last year, at 12 y/o, he got, a 4 x 3 at, 268 yards with, same,. gun / Bullet ( Prone over, a Pack ).
We take him out to the rolling Desert hill country, outside of Town to, practice Sitting with Stix and Prone shots to, 300 yards on 10" Steel plates.
A .243 Win with, the "Right" Bullet, is an awesome, Women / Kid's Cart. choice,.. IF, you know it's, "Limitations" and Practice with, it.
He's, a "Lefty" too, due to having, a Left master Eye, so we taught him to shoot, left handed.
Myself, having Shot Deer with everything from, a .22-250 Rem to, a .338 Win Mag ( they ALL "Work" some, just a TAD "better" than, others ! ).
I used to use, a .270 Weatherby Mag. on, Deer / Antelope and IT, killed,. very, "Well" and YUP,.. T'was,.. PRE- Range Finder, Days !
