430man, each animal is a biological example of one and they all do not give up the ghost at the same rate. If you have had trouble putting game down with a 45-70 then that is your experience and that is it. I have consistently put game down faster with a 338 win than a 375 H&H and that is my expereince, others had a different than I and my experience proves nothing other than it was my experience.

The 45 Colt has always killed considerably better for me than the 44 mag and the faster 454 has also killed extremely well for me
