I've taken three elk and four deer with 30/06 Hornady light magnum 180 grains and have had exelent luck with them. I have not had a single one come apart yet. The worst bullet I have ever seen for exploding was the old Federal rounds before they started using the Noslers. I saw a friends deer with one entrance wound and exit holes in all four quarters, no kidding, shot to pieces with a single shot.
