I have read that during the War Between the States, it was pretty common for soldiers in the heat of battle to leave the ram rod in the bore. Black powder is pretty low pressure so the guns probably didn’t blow up every time.
It might even launch the ramrod like a missile.
Still, not a good thing to shoot your ramrod across the field while you’re in the midst of battle.
35 years ago a bunch of us were plinking with our black powder rifles and one guy was using a heavy glass range rod with a T handle to reload his 50 T/C Hawken. He left the rod in and fired it by accident. That brass crescent buttplate gave him a great bruise and the rod went about 300 yards and stuck in the mud flat. We sawed about an inch off the end and glued on another tip and the rod and rifle were good to go.
Have been in many Civil War museums across the country. There is almost always a display of bent and twisted rifle-musket ram rods. These had been shot at the enemy during the heat of battle.
It has also been documented that a number of soldiers would never fire but just load and load and load... have to see if I can find the references.
