+1 on what mortimer says. My bps has a bead and I practice on stationary clay pigeons. They are perfect as they are about the size of a human heart, or even a head. At any range that would be reasonable in my house I can hit them almost every time, and I'm a noob to shotguns. It also helps in that it is easier to transition between multiple targets. I normally position my targets about 5ft away from each other so it is somewhat realistic.If it ain't broke don't fix it.
