Im haveing the same problem with my browning gold hunter 12ga. So what exactly is pb blaster. I have soaked the end of the barrel in oil for days and still couldnt get it even to show a sign of budgeing. I have broke about two or three choke tube renches trying to remove this thing.
PBblaster is a deeppenetrating oil like the other guys said. I took the barrel off and and soakedthe choke endin aboutfive inches of PB blasterin a cup overnight. I think a big thing that helped free it was hitting/tapping my wrench with a hammer while trying first to tighten and then while unscrewing. I think this would be alot easier with two people if you can get help. good luck.
