I guess it would depend on your taste or maybe if you have a lever action rifle in either 45Colt, 454 Casull or a 45-70. If you want a double action then the 460 is your only choice between the two. If you want to shoot more than one caliber from your revolver than the 460 is your only choice between the two, as it will shoot 45Colt and the 454 Casull. If you like shooting heavy bullets with low pressure than the 45/70 will be the better choice – shooting a heavy bullet with 60,000psi then the 460 would get the nod. The S&W X-frame and the BFR are both big revolvers and I think you would be happy with either one. I’ve heard the BFR 45-70 is one ugly, heavy, long cylinder puppy but is extremely accurate and those who have put their money down have nothing but praise for the revolver. I own neither caliber in a handgun.
