No the steel shot will pass through the turkey without any
knock down power.
And the turkey would fly off then die and be lost.
You would be better off to use copper plated lead or some of
The other shot that takes place of lead.

This is how it was told to me.

Like I talked to a duck hunter and he used steel shot.
He would shoot ducks and they would fly a long way,
Before dropping and he couldn't get them.
His buddys was useing bisthmuth ( Not spelled right. )
And they dropped on the spot.

So I wouldn't try to use steel shot on turkeys.

JMHO
