Can I shoot the Firebird in a Clay Pigeon from any angle?

For the Firebird to function, the pellet (or shot) must first penetrate through the red lid and then compress the pyrotechnic composition inside against the back wall of the metal container. The most effective way of achieving this is by using the Clay Pigeon as either a driven bird or a crossing bird.

It will be far harder to detonate the Firebird if used, for instance, as a going away bird. In fact, the Firebird is not likely to detonate if struck through the metal container first.
