Has anyone heard of or tried this shell deflector before? Last weekend I took the Revere's Riders basic rifle course which was awesome BTW I highly recommend it! There were about 12 of us out of 30 shooting center fire pelting each other with hot casings. This deflector looks like it would prevent my hot casings from hitting my neighbor on the firing line.
