RE: Powerbelts
I haven't used the 223, but have used the 245 in areo tip and killed a decent eight pointer this year with it. It was broadside at about 40 yards I hit it a little high, and the bullet went in between the ribs on the foreside and exited on the far side after hiting a rib. The exit hole was about twice the size of the entrance. He ran about 45 yards and piled up.
