+1. IMHO the 45-70 comes into its own with big, flatnose cast bullets at trapdoor velocities. My personal favorite is a 405 grain flatnose bullet (air cooled wheel weights) at a bit over 1300 fps. My two cents.Also, do you cast your own bullets? If you do it will make your rifle much more practical. Those factory bullets you mentioned have a lot of promise, but they are pricey for plinking. A whole lot of really big critters have fallen to that caliber with lead bullets..
