Make small slits in the mesh just large enough to allow your gun barrel to stick out and blast away , if the muzzle is at leat 8"-10" past the mesh/wall fabric you'll be ok . When I hunt from mine , which doesn't have mesh , I just zip the windows up to "murder slits" and poke the muzzle out when the deer show . This also helps with scent containment and keeps game from seeing me move . It also solves that pesky "black hole" problem .
