Most of my BP's,,,,,
I got from folks real cheap cuase they did leave them loaded and then didnt know what to do later when it wouldnt fire!
The first one took me by surprise, I didnt know it was loaded and loaded it! 3 caps later, it still didnt fire, so I took it to the gun shop, told the guy my predicament, and he took off the nipple, poured in a litle powder, took it out side and touched it off!
side note here, I did try the ball extractor,it pulled right off the ram rod! They are junk! MHO!
Its just easyer to pull off the nipple and pour in a pinch of powder and shoot it. I leave mine loaded for the season, and discharge it after season! Then I can clean it and know its ready for next season!
Just sayin!
