One thing you are forgetting Jack is, the man is shooting an in-line muzzleloader. Not a CF rifle. I don't care how good you can lock up your position, your front sight is still going to move some while aiming. You have to get your timing down with THAT PARTICULAR RIFLE AND LOAD because of the slower fire time. All your other suggestions are spot on but shooting a ML is a whole other animal because of the varying lock times and fire expulsion times. You have to be intimately familiar with a particular rifle and load in the ML world. Much more so than with any CF rifle.
