I set up my shotgun practice area to replicate the my house, specifically the sleeping quarter/likely 'bad guy path' interface. With a cylinder choke on the bird shot side and a laser, you might be surprised how easy it is to land pellets on the face/neck portion of an 11x20 silhouette gong even when out of breath and rushing the course in different scenarios. The follow-up tap to the body with a laser-equipped DP12 is far easier than with conventional shotties. I've also seen first hand what 00 does to steel lathe and plaster walls. In the ranges I'd be dealing with, bird shot first makes sense on the first shot. I wouldn't use slugs. YMMV
