I have done it in my earlier days and it does work. I also didnt have any problem with the barrel afterwards. If I said how expensive the gun was that I did it on some people would come kick my a$$. I am not recomending it but I just pulled a bullet with pliers and loaded a case with just powder into the chamber and shot it.
