RE: Model 92 Lever Action .454 Casull!!
I agree eldeguello. Maybe some of the early Winchester made M-92's if converted, may have a slight chance of some kind of failure if converted to the 454 Casull. The metallurgy and the hardening of the steels used in firearms today are much better, precise, and stronger, than those made 50-100 years ago. I am sure that Legacy/Rossi did extensive pressure testing to absolutely sure that the pressures generated by the 454 Casull could be safely handled by their M-92 Puma. I would feel completely comfortable shooting a Legacy M-92 Puma, but I don't think I would feel comfortable at all shooting a converted 1920's circa Win. M-92.
