The way to avoid dry balling is to have a system and stick to it. I have had a couple that work for me. The best was one that a friend in Indiana taught me. I got a 1/4 inch dowel rod and cut three 6 inch pieces. Then I got three different colored plastic jugs. One was an empty milk jug, one was an empty Tide detergent jug and the other was some kind of garden stuff jug. I don't remember what was in the garden jug. I cut one 2 X 3 inch flag from each colored jug. The milk jug gave me a white flag, the Tide detergent gave me an orange flag and the garden stuff gave me a green flag. I taped one flag to each of the pieces of dowel rod. When I was shooting, I kept the three flags in my range box. Then when I wiped the bore, if I was interrupted at this point, I would just grab the white flag and stick it in my bore and attend to whatever was the source of the interruption. When I returned to loading, the flag let me know exactly where I was in my loading process. The green flag let me know that I had added powder and the orange flag let me know that I had seated the ball and the gun was ready to fire. When I faithfully used this system, I never dry balled my rifle. Unfortunately, one day I went off and left my flags laying on the loading bench and do not have them now. I need to make some more. I hope whomever found them knows what they are for and is using them properly. My present system is if I am interrupted when wiping between shots, I stop and leave the range rod in my bore with the patch still on it. If I have added powder, I leave my powder measure in the bore (it is the kind with the little funnel attached. The funnel fits nicely in all of my rifle bores). If I have seated the ball and the gun is ready to fire, I leave my range rod in the bore. You notice that there are two times that I leave the range rod in the bore to let me know where I am in the loading process. In the first case, the patch on the end of the rod lets me know that I stopped during the wiping process. In the second case, if I withdraw my rod and there is no patch on it, I know that I have seated the ball and am ready to fire.
Of course, no system is foolproof, let alone idiot proof, so we just do the best that we can to be sure that we have some kind of system to let us know at what point in our loading process we were interrupted.
When, in spite of our system, we manage to dry ball our rifle, all we have to do is work a tiny bit of powder in behind the ball, fire the rifle in a safe direction and then check to be sure the the ball came out. If the ball is still in the barrel, work a bit more powder in behind the ball, re-seat it on the powder (a very important step) and then fire it out of the bore in a safe direction. If you are not around people who are muzzleloading rifle shooters, just act as if this is a normal part of the loading process and only you will know the truth. :grin:
