Aaahh, now we're talking... The 444 is the best... Better penetration (265gr) flatter shooting, less recoil.. I had both at the same time, I finaly sold the 45-70 .. To make it perform on par with the 444 had to load it up, then that lever action stock design beats you up.. Did these side by side comparisons while culling wild pigs over a two year span.. Have not used the 450, but can only think of it as a hot 45-70
