Re: Conical ball stuck--help!
The breech plug is a force on the charge, to keep it from blowing your cheek off. The charge and projectile go the less resistive path to the muzzle, because the plug is a "wall" or block to it.
A non-removeable plug is "timed", as in it will become snug against the bore inside, when the tang (bar at top) or hook is upright. When first installed, it is put in and taken out, and a small amount filed off the inside end. Continue taking a little at a time, then torque it in, until the tang or hook is upright.
If you take it out, and put it back in a few times after it has been timed/final torqued in place, the threads will loosen up or distort, and the next tightening will go past upright. Now the tang/hook is not in place where it should be. Which will screw up the barrel fit to the wood channel.
Or if you align them to being "timed" (upright), it might not be snug enough because of the thread distortion, and powder can get to the thread area between plug face and bore. Rust will form in there because a patch cant get to it.
And a loose/untorqued plug is a danger to the shooter.
Hope it doesn't sound too confusing! I tried to explain it with a tang for non-removable, or a hook for a removable barrel.
