I have read a lot on here about bullet traps and I reload in my basement. When I make a test load, mostly for handguns, I can walk out my basement door and shoot. What I want is a small bullet trap that I can leave outside all the time.Has anyone used a heavy hanging gong plate inside a tapered top and side metal trap to slow the bullet down before trapping it? The maximum distance will about 50 ft. Will be mostly bp and plinking loads. Thanks
