Everyone has given their opinion and some have given a lot of research and great information. The whole thing still comes down to that no one has answered his original question. So Mark I will give you mine. Your gun has 2 1/2" chambers and you are reloading low pressure-low velocity loads in 2 1/2". I would say that 7,000 psi loads and up to 1100 fps would be fine.
I don't know why with all the available shell sizes out there now and the low pressure-low velocity selection why anyone would want to shoot shells that were not made for their gun. Years ago ingnorace was bliss, but not today with all the information out there.

In gettng back to Sherman Bells article on "Finding Out For Myself" I believe he fired one proof round in each barrel and that was it. Since no one knows what modern shells actually produce in shorter chambers and you will be firing more than one why take a chance.
Just my opinion.
