Please take this in the spirit with which it is intended.
You need to find some DR shooters in your region and spend some time shooting with them. The questions in your last post suggest you are going to buy a heavy DG DR, without any experience. Take the time to learn about them. How to shoot them effectively on moving game. Stance, technique, follow through, aiming, reloading after the shot. All of that.
If all hell breaks loose, I want you to put 2 in the brain on reflex.
Take the time to do this right. Find a club. Join DRSS.
Nothing personal.
