We cut these AR 500 Steel Shooting Targets for a local shooting range.  This is a good example of how Waterjet cutting outperforms laser cutting.

With a laser cut part, the edges are affected by the heat of the laser. Heat causes distortion on the edges, so bullets can roll if they hit a distorted zone. With waterjet cutting there is no heat distortion, because there is no heat. Without heat affected zones on the edges, the bullets have less roll over on the edges. So if a bullets hits the edge, it’s a hit instead of a roll off.
