I just run 10 HOT SHOT 223 cases through my press, the primers came out and new primers were seated and cases sized with no problem Primers were not crimped and the flash hole size was no problem. I checked the length and they are 1.757 to 1.759 so I am not going to trim them. I'll recheck the length after I load and fire them. They seem fine to reload, but I will know for sure after reloading and firing them and check the cases again.
Still have no idea who makes these cases.
