You may laugh, but I'm looking at acquiring a Martini Cadet that has been rechambered to .32-40 (not a typo and I don't mean .32-20). It's not a double gun, but it could fall into the category of other fine gun and there's a lot of knowledge here.

I'd like to find some data for a light cast bullet load, preferably something in the 120-135 grain category. I'm concerned that the heavier bullets won't stabilize in the Cadet barrel without pushing them so hard that I either create a much heavier recoil than is preferable for accurate shooting in such a light rifle. This is going to be a plinker, not a hunting rifle (well, maybe a turkey or a chuck, if I can find a place and the time), so comfort is far more important than maximizing the energy of the cartridge.

Anyone have experience with such a critter or a source for load data?

Thanks.
