I can't speak to that cartridge in that gun but I had a BFR in 45-70 and it was a very well built and accurate gun. I had the 7.5" barrel and with a scope on it the gun balanced ok but that version is just a very heavy, large gun, the 454 has the smaller cylinder and frame I believe so it should balance much better. The price is avg for a new one from a store and is reasonable but if you keep looking you can probably knock one to two hundred dollars off that price, especially if you go used.
