I've mostly been using 130 and 140 grain Accubonds in my 6.5 CM, but I'm thinking about trying the 143 grain ELD-X since it offers the benefits of a high BC.

I would probably be using it for deer and antelope but I imagine it gets used for elk too. Looks like it's a conventional cup and core design with the interlock ring. The reviews I've read vary quite a bit with some saying they get consistent performance and good penetration while others say they sometimes don't get good penetration.

What are your experiences with the performance of this bullet on game?
