I have a 20 gauge over 25-35 combo rifle that I acquired last year. I just came back from the gunsmith shop where it has been residing the past 6 months (much to my consternation). He is fixing some stock related things that were not done properly by his apprentice last fall. It is looking good though!
Anyway, I have a bunch of information on the 25-35, old reloading data and magazine articles that were sent to me by a fellow campfire member. I used this information to work up a load using Hornady's newer 100 FTX bullet and CFE-223 rifle powder. Works great! I did have the gunsmith lengthen the chamber and forcing cone on the 20 gauge barrel last fall as I didn't want to source 2-1/2" shells exclusively. I did shoot some AA 2-3/4" rounds through it before the work and nothing bad happened
