Admit it MLKeith, you did that on purpose to make a bigger entry hole.. Out of curiosity, how far did that keyhole bullet travel inside the animal and what kind of damage did it do,

A while back I was shooting Shockwaves of all things and on the target got a perfect keyhole with the bullet. I was actually shocked to see it, but the out line through the paper was unmistakable.

It was a .50 cal. 348gr. Powerbelt plated aerotip. It was only being driven by 80gr. of the Clear Shot (I think that is the old Goex one). It passed completely through a large cow elk (estimated 875lb walking - I got 375lbs. of deboned meat). It went completely through the heart and lodged in the far side ribcage. Distance was 80 yards. The plastic tip was still in the bullet and there was only a small dent on one side. I suspect I could have been reloaded and probably shot again. The cow walked slowly about 30 yards and fell over. Apparently the secret to keeping the Powerbelts together is to shoot them sideways. I have since decided to try to shoot pure lead conicals if I can get them to print OK. I have shot some .295gr. Powerbelts and had them go completely through the ribcage also. I have shot some other 300gr. bullets and am starting to believe that to drop an elk fast you need to have heavier bullets as none of mine have fallen down on the bullet impact like some of the outdoor shows indicate. I put two 300gr. bullets completely through another cow elk and she went at least 1/4 mile after and was still standing when I caught up with her. Both lungs were hit as well as a portion of the liver.
