I just picked up a used Browning Buckmark today, its my first gun. Seeing it was a little dirty I purchased a boresnake after reading about them online. Well, I just tried using it, and it gets to the first set of brushes then jams in the barrel. I could not pull it through anymore and it nearly broke my hand pulling it back out. Tried twice, no luck. Please help a noob, what am I doing wrong? Thanks!
