Advice Needed on a Youth 20 Gauge Turkey Setup

[IA Born]

My daughter shoots the Mossberg Bantam 20 gauge with a HS Strut Understaker ported turkey choke. I'm a big fan of the knock down power of the Heavy Shot, so I have her shooting the Heavy Shot Magnum Blend (5,6,7 shot). It patterns great to 40 yards. I always tell kids to aim at the waddles or just above because its a big easy point to fix on, but center neck is the norm. Good luck!
