yesterday at our club shoot my buddy dry balled his shenandoah rilfe. its a .50 caliber. he tried pulling the ball with a large t/c style ball puller and it yanked out the center of the ball. in the process of trying top seat the ball screw he pushed the ball further down the barrel into the powder chamber. there was no way to get the ball out aside from pulling the breech plug. i know pulling the breech is a last ditch no other way choice and this was it. he pulled the drum first and found out the breech screws in past the drum and the drum passes thru both the breech plug and barrel wall. once it was out the ball had formed a doughnut of sorts smashed down into the powder chamber. i know where he went wrong, aside from no powder, and it was using the wrong sized ball puller and pushing it down too hard. if you ever, and im saying in absolute bad need, have to pull the breech on a traditions barrel be sure to pull the drum or vent liner first or the breech wont come out and you may break something. once he got it out i can see why these rifles have had some ignition problems. theres a small pocket there that the ball smahed into that makes a fine crud depository. he threaded his drum into his plug and did some work to the powder chamber and it should fire better now.
