Can anyone suggest a source for 10 gauge, 2-7/8 inch low pressure loads? I'm looking to start handloading for my Darne and my Hollis hammer gun. If possible, I would like to find something in the 1-1/8 ounce range for the Darne (weighs under 7-1/4 pounds, fluid steel barrels) and up to a 1-3/8 ounce load for the Hollis (weighs 8-1/4 pounds, Damascus barrels). I'd like something I could use for waterfowling (ducks with the Darne, geese with the Hollis) as well as for pheasant (Darne) and turkey (Hollis), so safe non-toxic loads would be greatly appreciated as well.

Thanks very much.
