I have no idea how you could read spacebacon's comment and conclude that he believes
damn near half a meter of plywood would be insufficient to stop a 9mm bullet. That's so absurd it should have stopped you in your tracks and had you reevaluate what it was spacebacon was saying. How can you seriously believe he was claiming to have experience shooting at
half a meter of plywood? The very premise is absurd.
Either spacebacon is completely insane, or he was talking about nilered's video. You chose the 'he's insane' interpretation. I say you're obviously wrong.
