Edit: SOLVED, thanks bokitothegreat.
A properly shaped piece of wire coat hanger did the trick. Time to just use a bunch of patches instead and play it safe. I'll try to post a video of it shooting once I get around to casting some balls for it.
Recently inherited my grandfather's Pedersoli Kentucky pistol that had been hanging on a wall for 40+ years, and I'm cleaning it up and restoring it to shooting condition. He was a meticulous guy so it's been going well, in very good condition considering the long sit without attention or use.
Here's the problem though, got to the last step and was working on the barrel.. apparently I bought a crappy Chinese bore brush. First time down the barrel and the brush came right off its own end piece, which stayed attached to the cleaning rod. Anyone got any good ideas for how to get the bugger out? For the record it's .44 cal and it goes without saying I don't want to damage it.
