recieved a call yesterday from a gent who said his son was doing a 4H project to make a duck call whistle and to do that he needed a few empty hulls in 12g hi and low brass. Well they came down from Truro and well we went out and made full hulls empty -LOL needless to say I think they went away happy . So I looked it up on the Internet and sure enough there were the videos on how to make them . They promised to send Pictures or video of how the young fell did. PS The young fella never fired a shotty before ;D lets just say that cherry is broke- ;D
