I'm considering using a factory Tupperware stock for a walking hunter build. What have you done to stiffen these stocks up and make them useable ? Has anyone filled in the hollow portions of the forearm with epoxy or fiberglass resin or something else? I've read of some using an aluminum arrow embedded in the forearm and then epoxied over. What about weight in the butt for balance?
When I get it all ready I will paint the stock.
Ideas? Experience?
