I guess I'm what you'd call the assistant match director for my club's outlaw 2-gun match.  The new MD and I are looking to spice things up.

One of our ideas, if we can get the club to fund it, is to construct a modular shoothouse in one of the bays that we can change out both interior and exterior walls on.  I'm thinking of using a large carport as the basic framework and using PVC-framed snow fencing walls.  Exterior walls would be lashed to the framing, and interior walls would be suspended from an overhead wire or rope grid, then anchored at the base.  This way the entire interior and exterior layout of the house could be changed match-to-match, or the whole thing could be left blank, and a standard stage could be setup with minimal interference from the house's frame.

With this setup we could potentially have targets set up both inside and outside of the house, as long as we periodically replace the snow fencing.  All fire would be oriented forward of the 180, obviously, since the walls of the house would not be bulletproof.

I'm curious if any other clubs out there have done something like this, or if any of you have any better ideas on how to build such a thing.  Google isn't really producing anything.
