Have the BPI reloading book, but none of the recipes seem like low enough pressure.

I want to reload for a 1929 Fox HE (2 3/4" gun), and an 1899 fluid steel-barreled LC Smith with factory-lengthened 3" chambers (NOT going to try 3").

Where can I find some load data to put through them so they can go back out and kill a few ducks?

Thanks for the help...
