CDR is right. If you don't plan to reload - 20 or so factory rounds offset any "great" purchase price difference.

I have reloaded 45 Colt, 44 Mag, 454 Casull, 460 S&W, 50AE (for years) and now reload S&W 500 (last couple of weeks). A must do, IMO, for the big bores.

Will you reload? How many rounds per week/month will you shoot?
