I have used Oregon Trail cast bullets in my 454 Casull, 255gr SWC and they did a very good job. I had very little lead fouling. My hands seem to shake a lot more now than they did so I won't try to tell anyone if they are accurate or not. I was pleased with them. I use RCBS dies, Star brass, CCI 350s and 296 powder. Isn't life grand. I have the Raging Bull with 8 3/8 inch barrel.
