Call me stupid but I had to do it. A local gunshop had one of the Nepalese P1837 Brunswick Rifles for sale in really good condition and its was only $350. Well now I have found out that every rifle is different and the mould must be made specific to your rifle. That being said I contacted Jeff Tanner of Round Ball Moulds in the UK and he said I must slug my bore. Apparently this has something to do with pouring molten lead down into your bore and then mailing it to him so he can make a belted ball mould. My question is how would this be done without getting the lead stuck inside of your rifle ? Has anyone ever done something like this before here on the forum ? Thanks to all replies, im sure the answer is simple Im jusy kinda slow lol.
