My regular grouse load in 16 gauge is RST papers and I like them a lot. I don't reload any 16 gauge, but the RST papers seem to have a thin wall (as compared with Federal 12 gauge papers) and I wouldn't be surprised to learn they split easily if reloaded. The difference in wall stiffness may be easily felt with a fingernail. Actually the RST paper hulls remind me of Fiocchi 12 gauge paper hulls that have a thin wall and won't stand up to repeated reloading.
Just for info - I load tons of Federal papers in 12 gauge on a MEC 9000 progressive press. That's with a 6 point crimp. With moderate pressure loads I'll get 4 reloads without burnthroughs just above the base. Higher pressure loads will last for 3 reloads. The wad guide fingers on the MEC allow the plastic wad column to enter without fraying or damaging the mouth of the hull. What I've written here applies to the newer Federal paper hulls. I had a batch from once fired shells that I bought in 2006 and they often split after 2-3 loadings. I've also loaded a lot of Federal "Champion" paper hulls from the days of yore and they will last for 4 moderate reloads. Thus the newer Federal 12 ga papers seem to be on par with the Champions.
