I think I heard it say 300yds at some point.It sure looks safe enough to me. Wondering how long the range is, didn't hear anything on the video regarding that. Noticed one younger guy shooting what looked like my K31!
That is a very cool range. The video did a bad job of explaining how and why it is safe but I figured it out around 2 min in. Or maybe it is obvious and I'm dumber than a bag of hammers.
