Yup, I used to shoot this one. It was called BLACKLIGHT INSTINCTIVE SHOOTING. All stock, no dot sights, no glow in the dark sights. Basically all iron sight. They used four silohette targets at different distances, with the targets ooutlined in marker that glowed under blacklight. One was outlined the left half of target spit down middle, one outlined right side split same way then one outlined bottom half, split across center, the last was top half split at center. The part of the target that was outlined was for + points, if you hit the other half of target it was - minus points. And it was timed, with reloads. You got on the firing line got ready and on command the lights were shut off, and the Blacklights were put on. It was shooting in total darkness, wit the objective being proficient at point shooting in the dark. Fastest time with most points was the winner. It was a lot of fun, dont know if they still do it though.....P.S. It ws shot indoor range.....
