I thought you passed on the 25-20 because you knew a bottle necked, rimmed cartridge, are hideously hard to load when you are facing a deadly charge from a terror which you are facing in the rascally rabbits in Wisconsin. Should be fun working up a few loads to get the maximum performance out of that rifle. And shooting even a few hundred rounds to do so should not give you either a headache or flinch like I got years ago with a .458. Fun project and nice outcome.
