Don't judge a bullet by only one kill...It takes 6-8 to really make a fair judgement...I've killed about 90 with a CoreLokt, but it was out of a .243...It's not unusual for a lung shot deer to make it 100 yards, depending upon what it hits when it gets there...

If you want a bullet that opens up faster than a CoreLokt in an '06, try the Winchester SilverTips in 150, they are about as cheap as a CoreLokt and when my hunting partner was shooting an '06 he did well with them...
