You could search on youtube there has got to be somebody who shot up some test drywall out there. Or if you have access to some open range/farmland and don't mind the mess, rig up a wall with 2x6 construction and add the insulation just for kicks. then shoot it with various loads and see what goes through. you will then know for sure if the rounds will go through a wall or not. Do the shooting from 5 feet away and closer then you will get a feel for what they do or not do. It's the only way to know for sure if you have to know.
