Non-tox load for 28

I have a son I am ready to introduce to duck hunting. He is already doing well on dove with 28 gaugeand is not ready to shoot a 12 gauge. Anyone have any tips for reloading a 28 gauge non-tox shell. The only guides I have found for non-tox are for 12 gauge.

To those of you who view this posting. I found some good info thru Ballistic Products, Inc and will be trying the loads for ITX shot for the 28.
