BP,
Good advice from the boys, but I must be missing something. I clean three of my own made flinters by taking the barrel out, and no hooked breech. I use keys on two and just pins on one. No problem. I like to remove the wedges, and tang screw, and then hold the rifle upsidedown over a padded bench with the barrel on the pad. Then I pull the stock up so I don't break the thin wood next to the barrel flats. Put back is in reverse order.
Flintlocks Forever,
Lar :thumbsup:
