I believe that once you reach the performance of the 458 Lott you have reached the point of diminishing returns in .458". This being true regarding performance for recoil. Past Lott performance you should go up in calibre and bullet weight and not just up in .458" velocity, either with 500 or 550gr .458" bullets.

And by the way, those fellows who have used the Lott with 550gr bullets swear by them.

The 500NE, which provides a 570gr bullet 2150fps, delivers more on game performance than the 458 Lott or 470 Capstick, according to a fellow who has used all three on game. (at least the Capstick and 500 for sure, but I think all three)

For what it's worth,
