I was loading some fiocchi 28 ga and was having the Winchester 209 primers fall out.  I got a primer pocket swage from Ballistic Products and now they hold the ww's no problem.  I may have to do the same with some .410 Fiocchi hulls I got from bp as well.

Another approach may be to use Cheddite primers.  I understand that they are just a hair oversized like the Fiocchi.  Reloading wise, I heard that the Cheddite and the Winchester 209 are about as interchangeable as can be done, but I have not seen this from a reliable source.
