I’ve seen both of the ones you posted, and others, at trade shows, but have never tested them. Bullet Trap USA is the only one I’ve personally shot on the inside of a structure, and it was a pole building, not a basement. There’s also a problem with air filtration and outside noise for the neighbors, with large rimfire calibers.
My best advice: shoot the .17cal inside, and go to an indoor range. Let them bear the cost of the range, noise, ricochets and filtration.
Since I moved to McLean ranges are now an hour + away with all the bad traffic here in DC.
I have to break in my new Kel-Tec P32 and you have to run 200 rounds through it before it’s reliable they say.
Guess I’ll have to suck it up and hit the road.
