I made mine from a heavy duty artificial Christmas tree storage box, 4’x1.5’x14”. The wife sent the Christmas tree to Asia in a balik bayan box, so I got the Christmas tree box.
I wrapped it in leftover laminate flooring sound insulation, then rewrapped it in old exercise mats, cut a 3x5” rectangle hole in each end. I set it slanting on two end tables, my Caldwell tripod sets at one end with the Seneca 25 carbine shooting 58 grain slugs on full power sets with the koi inside the box up to the forearm, the sound reduction is absolutely dramatic. Sounds like a 1/3 force canefou strike on a leather couch cushion, a quiet thump. 10 yards away is a Morrill crossbow target and a 15 lb block of duct seal so no noise on that end either.
