In the early 80's, I got called to the Office of the RTE Shop and there stood a Stafford Country Deputy Sheriff with a reproduction Walker. A crook had loaded it with SMOKELESS POWDER and a Modern Conical bullet and shot at the Deputy ONE time with it. AFter I found that out, I asked what happened to the crook AFTER he pulled the trigger the first itme. The Officer started laughing because the pistol recoiled so hard and hit the guy in the head, it ALMOST knocked him out. He saw the crook drop like a sack of potatoes and let the pistol fall as he fell. He covered the guy for a little bit before he realized the crook was hurt and then walked up and cuffed him without difficulty while the crook was moaning. I could not believe the cylinder had not let go.
The Deputy had brought it into us because his department did not know how to unload it and it still had the percussion caps in place. I checked with him as to what kind of evidence procdures they used and then pulled the cylinder out and handed the Deputy the rest of the pistol and asked him to come back the end of the week. I cut the top off a soda can and filled it about 1/3 with penetrating oil and then carefully put the cylinder in it and then filled the can over the top of the cylinder. Took the caps off two days later and pulled the bullets and powder the day after that. I saved each bullet with the oil soaked powder and cap from each chamber separately. When the Deputy picked it up, I told him I would testify about what I had done if they needed it for the prosecution. The crook's lawyer wisely talked the crook into pleading guilty and got a smewhat lighter sentence for it, so they didn't need it for the prosecution.
