My point was that the matches are supervised and controlled. It is way too easy for someone who is alone to slip/trip/fall and let a shot ot of the range or worse shoot themselves and that could be tragic. In Cowboy action we move with loaded gns, but are not firing. I can see someone trying to shoot and run at a target and whoooppppsss.....
I definitely agree that things like Simunition are MUCH better for move-and-shoot training. Risking the use of lethal force for training should be left to very advanced, very supervised training.
