Re: 454 Casull Anybody?
There is NOTHING wrong with Starline brass.
If you shoot ANY kind of brass at the top pressure the 454 Casull can operate at (i.e., 60,000 psi) and the chamber of the gun it's originally shot in is larger than the chamber of the gun it's reloaded for, you can get sticking of the cases. Also, with the 454 Casull you need to full length size the case.
Also keep in mind that originally, the 454 Casull was only available in Freedom Arms revolvers. Being a single action revolver, only one case is ejected at a time. Also, in case you've never seen a Freedom Arms revolver in person, the chambers are very precise and highly polished which assists in ejection. If you're shooting a double action revolver, you'll be ejecting 5 cases at once which makes ejection more difficult. Add a dirty or not so polished chamber and the problem is worsened. For brass used in a double action revolver, it might be necessary to lower the load a bit to avoid hard ejection.
