10m home range project.

You'll have a very hard and reflective interior and with top and bottom parallel and sides parallel. This all leans towards a potential noise problem, IMHO. It would be prudent to allow access to the inside once it's assembled; if nothing else put something down the tube that breaks up the continuous flat surfaces.

Our plastic barrel tube mentioned above had five 45 gallon steel drums joined end to end and with the tops and bottoms removed to form the entry part where the shooter was positioned. We soon had to stick some old carpet on the inside of the oil drums.

As you say, it will be a bit loud as is. The out side lagging will take care of the top and sides. The floor will have some thin white carpet on it on the inside. Don't worry, it's designed in my head. I may even put a very small extractor fan at the back on the bottom for a little through ventilation.

I used to lag duct work in building to kill the noise (not as loud as an airgun shooting through it mind you)

we used glass wool that had a ali foil on the outside .

Anything soft will soak up sound. Carpet, foam, old duvet etc.

Ensure you have enough room to swing the rifle from above and from the side. Depending on your level think about how much room you'll need to put the rifle on a stand between shots and a mirror. A target whizzer would save you loads of time. Lighting that works with scatt etc.

Make the range usable and you'll use it more. 10m at home is a really nice thing to have.
