I'm trying to come up with ideas to deaden the sound of my test shots in my basement range. I'm thinking of constructing a really basic box. Something along the lines of an OSB box 24" by 48" and lined with insulation. Maybe the end closed down to 18"x18". Essentially, you put your firearm into it, sight down it to your target, and the insulated box deadens the blast. Or at least that's the idea. It certainly wouldn't silence things but I think it might muffle 22LR-? to a fair degree. Not every gun is suitable for a suppressor and this is just an idea that I thought might help lower the noise a bit.
Has anyone else thought of or tried something like this? Or is this just a waste of time?
