yesterday i cleaned my bore with some super concentrated lead remover a friend gave me,unfortunately could not read the name, only takes 3 drops and 1 oz. will clean 80 guns and my 100 yard groups went from 12-18 inches to 2-3 inches. AMAZEING, i am very happy. 80 gr. FFG goex. 4-6 inches low. how often should a flintlock be cleaned like this?, and what are some STRONG cleaners as i dont believe HOT soapy water is the only necessary cleaner anymore, at least with my gun anyway. I did not even know my bore was dirty or fouled as my cleaning patches came out clean after 3-4 patches were used.
