I agree with sevens on the plated bullets being a real heck of a chore to get out. It was not an easy task to the get the squib out of my 4 inch Mod. 67, and it was not all that far in the barrel either. It took a while, and 2 wooden dowels to get it out. The dowels that will normaly push a lead bullet through slugging a well oiled bore will flatten out, splinter, and break trying to hammer out a plated round. I know I had to do it twice this weekend.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
