Model 92 Rossi in a 454 Casull(spelling). That would be a doozie(spelling again). Is the 460 S&W legal??? 45 long Colt in 1894 Marlin would also be a great choice. I have an 1894 Marlin in 44Mag. I cast a 240 grain bullet for it. Very effective to 200 yards. Be careful with large for caliber bullets in a Marlin. 240's in a 44Mag, and 250's in a45 Long Colt work great. A long barreled Encore would also be great with a slow burning powder. The H&R Buffalo Classic in 45 Long Colt would also be a classic-the longer barrel should give up great velocity. Doa search-I believe some one posted about having one. Tom.
