I don't care for the ballistic tips either as they can and do go to pieces prematurely on bone at under 100yards.Seen several large bodied deer with a busted shoulder resulting in little more than a surface wound.My buddy even quit using them on antelope 100gr/25-06 due to excessive meat damage.Exit wounds in the ribs you could stick your arm in.The earlier Nosler solid base was even worse.If you collect fur don't use these on yotes either.Bullet expansion relies on 3 things ,velocity,what is struck and jacket thickness[bullet integrity]....................The reason people like them initially is that they are scary accurate.On the other hand I have 2 early Barnes x 130gr .270 one that could be reloaded and fired again and another picture perfect expansion recovered from a 6x7 mulie buck.This is a case of too hard.............Harold If they are working for you that's fine but I now use Hornady interlocks for everything antelope -grizzly with no failures todate.20+years
