Need some idea on how to sound proof a storage shed. Im moving into a house that will allow me to shoot on the property; however I would like to do it as quiet as possible. I know I can just purchase additional suppressors however I shoot with a Bullseye team and putting a suppressor on the end of my target 1911 is out of the question. So my thoughts/plans are to purchase an 8x12 shed from Lowes and use that as my shooting house, actually shoot out of it through the window. So other than the standard pink insulation what else is there that will cut down on the noise? Thanks for the help.
