Mossberg Super Bantam Ammo Question

[treefarmer]

My grandson has a new Mossberg Super Bantam 20 Gauge. I bought him a Hevi Shot choke for it. Do any of you have experience or an opinion as to whether Hevi Shot 13 or Hevi Shot Magnum Blend would work (pattern) best for 30 to 40 yard turkey shots with this combination of gun and choke? Thank you.

I Would like to know this my self. But I think Clark may have adressed this already.Check shooting forum.
