Man, if I didn't get excited and my heart didn't race before I decided to take a shot, I would probably be dead.
It is hunting and not shopping, you have to assume everything that can go wrong will. The last elk I killed with my flintlock last December after spending more than half an hour sneaking in on the bedded cow. I finally spotted her 70 yards away; I dropped to a kneeling position behind the juniper. I inched my way to where I had a lane. I put my rifle up, but I had to take it down and reassess the elk as a target and where the best place to aim would be. By the time I figured out the shot I was calm and was able to squeeze of the shot.
New fowler, I don't use a self-contained cartridge. I use loose powder and the ball block. The ball block pictured is the one I use for trail walks. I have a smaller one that holds five balls for hunting.
All the elk I have killed with muzzleloaders have been in the junipers. The moment you fire a shot the elk are going to take off. If you are in the junipers, you will be hard pressed to see them, but you will be able to hear them. I can reload pretty fast with my set up and I am a good tracker.
