Your gun can not be presumed to be safe with ANY load until you are able to answer Dean's question - what is the end-of-chamber, forcing cone, 9", and minimum wall thickness and where?
And are the barrels fluid steel or Damascus?

Titanic steel. It went to Briey for chambers being lengthened so I know it's safe to shoot because they check that there. I found a man in Bay City Tx that specializes in old guns and he is going give me all the answers y'all are looking for when I bring it back with me next week. Hopefully then I can figure out what it can take. In the meantime I'm on the hunt for some loose bismuth for reloading.
Thank you for your help.

Precision Reloading sells bismuth shot but they are out of #4s .
I suppose you could try a duplex load of #6s and #2s .

Parker service load and proof pressures are listed in TPS, see barrels chapter. TPS contains the answers to most Parker questions.

This is what I have used for over 20 years with fluid steel 2 frame Parker 12’s when I’m after pheasants or ducks.

I too like the Classic Doubles ammo in my Parkers for ducks.
