Killing Yourself For Points
From M2K2: Metroid Prime 2 Wiki

In the Shooting Gallery level, get a power bomb, then hurry to the turret. Kill your opponent, then get out, power bomb, and get back in. The turret is destroyed and you get a point for killing yourself!

Be careful, because the game counts deaths as well as kills.
