does anyone have anyreal good information onshootng the Ferguson Breechloading flintlock . I have heard the stories about them fouling up after four or five shotes , blow by etc but today I spoke to a man at a company (not the Rifle shoppe or Naragansat arms) that claims everyone has built them wrong and is shooting them wrong.1. He said the orriginal models had a groove on the bottem to axxept a leather washer which helped prevent the blow by on the bottem , he said completly if all else is done correctly . 2. He said the orriginal rifle was shot using a special fine grain German powder. He further said that he has found some special blend of goex that duplicated this but was not really willing to tell me how to do it until my gun was built and shooting , for some odd reason. 3. He said the orriginal guns had 90 grain chambers not the apx 72 you see now and the trick was to only load 60 grains leaving a cavity and also this would help to prevent getting powder in the threads which jams the action until cleaned. Now I realize this would prevent the old idea of cranking it up and pushing the spare powder in the pan but he says they shoot all over the country like this and have no problems done this way for many many many shots.Any ideas or other secrets of shooting these guns. ? I had a beautiful sporter some years ago copied after the Durrs egg model with gold leaves on the barrel and silver face on the lock , never shot it and had to sell it , hoping to one find it again and rebuy it . The action like the other action I just bought was made by Steve Sklaney in the 70's.
