Rick,

<br>Go with the 458, it is a very versitile round, can be loaded down to 45-70 levels, or up to most impressive levels! I won't get into the bad press issues, but I think of more importance is Winchester really messed up by not loading it for NA, launch a 350 gr @ 2500 fps, recoil is the same as a 375 H&H, and it hits with authority!
<br>
<br>Conversion is straight forward, just a barrel swap.
