.303 cases can make good .410 shotshells, but with the plethora of good hulls available for cheap like Winchester HD's, not much point.
senior, the problem with trying to swag down a .45-70 case to .45LC diameter would be twofold, the much larger rim would have to be turned down, and you'd end up with a case head bulge that might not chamber as the case head is much larger in diameter than the .410 or .45LC.
