In March, we took part in an interesting training session devoted to medium-range shooting. It was conducted by Jarosław Walczuk from TeamGrey Accuracy. The details of the training are described in this article. The participants used AR-15 rifles at ranges from 50m to 290m, and at the end they found out that even hitting a 10cm wide gong from a distance of almost 300m was not a problem.
Have a look at the video from the training we included below.
