Even though I've seen alot of elk taken with the core lokt Elkamp is right. Elk are alot tougher than deer and can absorb alot of bullets at times. I've actually seen an elk absorb (11) 7mm weatherby rounds before the hunter hit it where it was suppose to be in the first place. But in my mind I'm not a bone shooter I go straight for the lungs. But some have the mentality of shooting for shoulders and on elk size animals this can be distrastrous on elk. The only elk we have never recovered was from low shoulder shots. Even if it breaks the bone it can turn the bullet away from the heart and lungs. For the average hunter maybe a tougher bullet is in need. For the hunters that practice and wait for the perfect shots core lokts will preform just fine.

I use speer spizter boattails and these bullets are not bonded or partition style bullet. They are more of a match style bullet but made for big game. Never had one blow up or not go completely through an elk even at long ranges. Shot a trotting bull this year in the shoulders and went through both shoulders. It wasn't what I meant to do but I overlead the bull just a bit. But the bull only made it another 20yds so I guess the bullets I use are adequate.

I think at the wrong angles or hitting a mass of 2 1/2 inches of solid bone most bullets out there would turn off target.
