Noticed there are lots of Rossi owners on this forum and I have been thinking about getting one. Does anyone have a 454 Casull and shoot 45 Colt thru it? Does this cause leading in the chamber throat? Do the 45 colt rounds shoot as accurately as the Casull rounds? It looks like Rossi gives a lot more finish options in 45 Colt. I have been shooting some pretty stout loads thru my Ruger Blackhawk, is there any thing to be gained shooting the casull in a rifle? It would need to be a substantial difference to justify tooling up and buying brass for a new caliber. I already have 45-70s and 444 Marlins and 45 Colt in Ruger Blackhawks.
