I reload the HS shells for my 410, and I really like them. I am only on my 3rd or 4th reload and they seem fine. A lot of folks are getting 10-12 reloads out of them in the 410.
I have been told that the HS shells are only good for the 410 and 28 guage. I heard that the 12 ga. HS shells weren't that great, but I have no personal experience with them in 12 ga.
