If loading to mag length with a jump to the lands, any efforts taken to help the bullet leave the case central to the bore can't do any harm?

With hunting ammunition, and the range that most shots are taken at, the difference is probably negligible, but if you don't do it the niggling doubt that you haven't fully prepped your brass will always be there.
yup agreed, still worth doing if your punching paper might even turn that .40 group into a .35 and sorting your flash holes might turn that .35 into a .30 and so on. depends what your into.
