I make 2" .410s for my grandad's Peiper combination gun by cutting down once fired .444 Marlins. 3/8ths of an oz. of fine shot is OK for sitting pest birds, cottontails, and cottonmouths, but not much else. I only load black powder, tho, and use homemade paper wads. You don't have to cut the case back much, about .2 as I recall.
Only a cheap solution if you have a buddy with a .444 who doesn't reload, or find some cases at a range, as I did (Does being a brass hound necessarily make me a "brasshole," an apparently negative term I've heard at CA ranges? Heck, I thought being a "brass hound" was an HONORABLE thing, like being a "cheapskate" or a "gun nut".....maybe that's just me).
