I have loaded a lot of 16 ga in the Fiocchi and 28 ga. My 16s have been loaded several times. The Fiocchi 28s were mostly black powder and usually only do them twice from new hulls. The nitro 28s seemed to be ok. I only load to 1200 fps. in as low pressure as I can find. The hotter loads might be hard on the hulls. I had some ignition problems with some magtech brass 28s. Not sure of the reason but they sat the the shelf for awhile. I guess I like the plastic if you have a good roll crimper.
