Heavy rifle depends on which side of the pond you are on. Here, anything over a 375h&h is a heavy rifle. In Africa, heavy rifles start @ 458winmag & go up. I used to load for the 458lott, sold it, too much gun for me. I have been loading & hunting w/ a 404jeffery now for about 3yrs, love it. Full power 45-70 too.
