I cant even find one round of ammo.......and you want a whole box.
I did make copies of 8mm Lebel revolver box. The ammo that I have in the loops of the holster are actually cut down .303 British cases and civil war .44 cal pistol bullets I found in the back yard. They look good but that is all.
I did fit a few .303 cases with round lead balls and some black powder, just to have it go boom. Not bad accuracy at 20 feet.
