I read recently about hollow point bullets.....

a cavity or hollow in the bullet nose (hollow point) to shift the projectile's centre of gravity rearwards....

Holding the bullet and looking at the hollow point under a magnifing glass, you can see the hole isn't level on certain bulllets manufactures, and Berger is looking real good..

I remember seeing a hollow point uniformer.... does a uniformed hollow point help control the center of gravity?
