As far as expandables go, I've never shot them through the mesh. They aren't legal to hunt with in Washington, so I've never had the desire to test them out. I would assume, because of how thin the mesh is that expandables wouldn't be a problem though.Fixed blades are no problem at all, they go right through.

The mesh on the Ameristep blinds isvery thin, so much so that you could easily push your finger through it and create a hole. I don't know about Double Bull or any other company's blinds, but I'm fairly confident in saying that they would have the same results.
