As jdkerkstetter said, ONLY with the cock fully down or from the full cock position. It is completely safe to do it that way but NEVER in the half cock position. Dry firing of a flintlock, unlike a caplock, in the fully cocked position is okay, too. No harm is done other than to wear down your flint. Do not dry fire a flintlock from the fully cocked position with no flint in the jaws of the cock. This can possibly cause damage to the cock. If you want to save your flints while dryfiring your flintlock in the full cock position, you can put a piece of wood in the jaws of the cock. So, in summary, it is safe to dryfire a flintlock so long as the cock is in any position other than half cock and if you dry fire in the full cock position, you will need something in the jaws of the cock. If you dryfire with the cock all the way down, you will harm nothing and may feel free to do it as much you wish :hatsoff:
