I will try this exercise and vary he distances aswell. This will be good for reality where in South Africa criminals come in groups of 3 to 8 when entering your house. The surprice are almost always on their side when they operate, so when you go over for self-defence, it has to hapen quick.
So to do this drill on multiple moving targets it is a must to make every shot count.
What is the best firearm?
The one in your hand, when you need one.
