Wanted: 348 Cal. bullet 200 or 250 gr.

[Racer Dan]

Does anyone have a source for 348 cal. bullets? Looking for either 200 or 250 gr. for a lever action rifle, flat nose. Maybe 100 or 200, depending on price. Or a mold for them you don't need any more maybe? Or maybe someone who can make me a few? Maybe an old box or two of one of these: Hornady 3410, Hornady 3415, Barnes 30438.
Thanks for any help or leads.
I have a model 71 Winchester I would like to play with some at the range.
